+    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
+    HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display,
+     communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+     likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+     subject to the limitations in paragraph 4(a), below;
+  v. rights protecting the extraction, dissemination, use and reuse of data
+     in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+     European Parliament and of the Council of 11 March 1996 on the legal
+     protection of databases, and under any national implementation
+     thereof, including any amended or successor version of such
+     directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+     world based on applicable law or treaty, and any national
+     implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.

+
+* Introduction
+
+The *Älyverkko CLI* application is a user-friendly tool developed in
+Java, specifically tailored to streamline the utilization of expansive
+language models through CPU-based computation in batch processing
+mode.
+
+To illustrate its capabilities: Imagine harnessing the power of a vast
+language model, boasting approximately 100 billion parameters, solely
+relying on CPU computations and leveraging the open-source software
+*llama.cpp*. This setup requires a modern consumer-grade CPU and
+approximately 128 GB of RAM. To put this into perspective, 128 GB of
+RAM is financially comparable to purchasing a high-quality smartphone,
+making it an economical option for many users.
+
+In contrast, executing the same model on an Nvidia GPU could result in
+costs that are significantly higher, potentially at least by an order
+of magnitude.
+
+However, there is a trade-off: CPU-based processing for such extensive
+models is inherently slow. This means real-time interaction, like
+chatting with the AI, wouldn't be practical or enjoyable due to the
+lag in response times. Nevertheless, when deployed in a
+non-interactive batch mode, this "slow but smart" AI can complete
+numerous valuable tasks within a 24-hour window. For instance, it
+could generate a substantial amount of code, potentially exceeding
+what you could thoroughly review in the same timeframe. Additionally,
+it could process more documents than most individuals would be
+inclined to read manually.
+
+The primary objective of the *Älyverkko CLI* project is to identify
+and enable applications where this "slow but smart" AI can excel. By
+utilizing *llama.cpp* as its inference engine, the project aims to
+unlock a variety of uses where batch processing is more advantageous
+than real-time interaction.
+
+Here are some practical examples of tasks suited for the
+*Älyverkko CLI* application:

+- [[id:f38360ad-54f6-4f24-b299-f73a9faacabd][Domain: Content Creation]]
+
+In summary, the *Älyverkko CLI* application opens up a realm of
+possibilities for leveraging powerful AI in scenarios where immediate
+responses are not critical, but high-quality batch processing output
+is highly beneficial.
+
+Note: project is still in early stage.

+*Problem Statement:*
+
+Analyze a set of customer reviews to determine overall sentiment and
+extract key features that customers appreciate or dislike about a
+product.
+
+*Usage Procedure:*
+1. User collects customer reviews in plain text format within the
+   configured mail directory. Lets say, about 150 kilobytes of reviews
+   per input file (this is dictated by AI model available context
+   size).
+2. Each review file is prefixed with "TOCOMPUTE:".
+3. The Älyverkko CLI application processes these files, generating
+   sentiment analysis results and feature extraction insights.
+4. Results are appended to the original files in org-mode syntax,
+   indicating AI responses.

+
+*Problem Statement:*
+
+Generate code snippets for a new software module based on detailed
+specifications provided by the developer.
+
+*Usage Procedure:*
+
+1. Developer writes specifications in a text file within the mail
+   directory, prefixed with "TOCOMPUTE:". Text file also contains
+   relevant parts of the program source code and
+   documentation. Älyverkko CLI *joinfiles* subcommand can be used to
+   facilitate such text file preparation.
+
+2. The Älyverkko CLI application processes this file and generates the
+   corresponding code snippets. The generated code is appended to the
+   original specifications file, organized using org-mode syntax.
+
+3. Developer can review proposed changes and then integrate them back
+   into original program source code.
+
+Note: Most of the [[https://www3.svjatoslav.eu/projects/alyverkko-cli/][Älyverkko CLI]] program code is written in such a way
+by AI. [[https://www2.svjatoslav.eu/gitweb/?p=alyverkko-cli.git;a=blob;f=tools/implement+idea;h=02b0ceb260693a6c9733f221e52a0e6c5fce0a36;hb=HEAD][This script]] is used to facilitate the process.

+*Problem Statement:*
+
+Draft an outline for a book on science fiction and improve its plot.
+
+*Usage Procedure:*
+
+1. The book author writes a brief describing the outline of the plot
+   and his book main idea for the novel.
+
+2. *Älyverkko CLI* processes this description and generates an outline
+   with suggested headings and suggests possible improvements to the
+   plot.

+Here is [[https://www.svjatoslav.eu/writing/Whispers%20in%20the%20Stream%20of%20Time.html][example sci-fi book]] that was written with the help of

+
+* Getting started
+
+When you first encounter Älyverkko CLI, the setup process might seem
+involved compared to cloud-based AI services. That's completely
+understandable! Let me walk you through why each step exists and how
+it ultimately creates a powerful, private, and cost-effective AI
+assistant that works /for you/.
+
+** Why Bother With This Setup? (The Big Picture)
+
+Before diving into steps, let's address the elephant in the room: *Why
+go through this setup when ChatGPT is just a click away?*
+
+Because Älyverkko CLI solves a fundamentally different problem:
+
+- ✨ *Privacy by design*: All processing happens on your machine - no
+  data ever leaves your computer
+- 💰 *Cost efficiency*: Run 70B+ parameter models without paying per
+  token (128GB RAM ≈ cost of a smartphone)
+- ⚙️ *Full control*: Tweak every parameter to match your specific needs
+- 📦 *Offline capability*: Works without internet connection
+- 🕒 *Batch processing*: Perfect for "set it and forget it" workflows
+  while you sleep
+
+This isn't designed for real-time chatting (CPU inference is slow),
+but for substantial tasks where quality matters more than speed: code
+generation, document analysis, content creation, etc.
+
+** Your Setup Journey - What to Expect
+
+Here's what you'll be doing, explained simply with /why/ each step
+matters:
+
+*** 1. Installing Java & Maven (The Foundation)
+
+- *What*: Install JDK 21+ and Apache Maven
+- *Why*: Älyverkko CLI is written in Java - these tools let you build
+  and run the application.
+  - *Don't worry*: On Debian/Ubuntu, it's just
+     : sudo apt install openjdk-21-jdk maven
+
+*Key insight*: Java was chosen because it's cross-platform,
+memory-safe, and perfect for long-running background processes like
+our AI task processor.
+
+*** 2. Building llama.cpp (Your AI Engine)
+
+- *What*: Download and compile the llama.cpp project from GitHub.
+- *Why*: This is the actual "brain" that runs large language models on
+  *your CPU*. We build from source (rather than using prebuilt
+  binaries) so it can optimize for /your specific CPU/ - squeezing out
+  *maximum performance from your hardware.
+
+*** 3. Adding AI Models (The Brains)
+- *What*: Download GGUF format model files (typically 4-30GB each)
+- *Where*: From Hugging Face Hub ([[https://huggingface.co/models?search=gguf][search "GGUF"]]).
+- *Why*: These contain the actual neural networks that power the AI.
+- *Don't worry*: Start with one model (like Mistral 7B) - you can add
+  more later.
+- *Key insight*: GGUF format was created specifically for CPU
+  inference.
+
+#+begin_quote
+❓ Why not smaller models? Larger models (even running slowly on CPU)
+produce significantly better results for complex tasks - it's worth
+the wait.
+#+end_quote
+
+*** 4. Running the Interactive Wizard (=alyverkko-cli wizard=)
+- *What*: Launch the configuration wizard that asks simple questions.
+- *Why*: To connect all the pieces without you needing to edit complex
+  YAML files.
+- *Don't worry*: It's interactive! You'll answer questions like "Where did
+ you put your AI models?" with easy prompts.
+- *Key insight*: This creates your personal
+  =~/.config/alyverkko-cli.yaml= file.
+
+#+begin_quote
+🌟 Pro tip: The wizard automatically detects your models and suggests
+reasonable defaults - you're not starting from scratch.
+#+end_quote
+
+*** 5. Setting Up "Skills" (Your Custom Instructions)
+
+- *What*: Create simple YAML files defining how the AI should behave
+  for different tasks.
+- *Why*: So you don't have to rewrite instructions every time ("be a
+  coding assistant" vs "be a writing editor").
+- *Don't worry*: Sample skills come pre-configured - you can modify
+  them gradually.
+- *Key insight*: Skills let you create specialized AI personas without
+  changing models.
+
+#+begin_quote
+Example: Your =writer.yaml= skill might instruct the AI to "always
+provide well-reasoned responses in academic tone"
+#+end_quote
+
+*** 6. Preparing Your First Task (The Magic Moment)
+- *What*: Create a text file with your request, prefixed with
+  *TOCOMPUTE:*
+- *Why*: This triggers the background processing system
+- *Key insight*: File-based interaction isn't primitive - it's
+  intentional design for batch processing.
+
+** Why Files Instead of a Fancy UI?
+
+You might wonder: /Why deal with text files when everything has
+beautiful interfaces these days?/
+
+Because *this is designed for productivity, not conversation*:
+
+1. *No waiting around*: With CPU inference, responses take
+   minutes/hours. File-based workflow lets you queue tasks and get
+   back to work.
+2. *Natural integration*: Works with your existing text editor (VS
+   Code, Emacs, etc.) rather than forcing a new interface.
+3. *Version control friendly*: You can track changes to
+   prompts/responses with Git.
+4. *Resource efficient*: No heavy GUI consuming precious RAM needed
+   for AI models.
+5. *Scriptable*: Easily integrate with other tools in your workflow.
+
+Think of it like email versus phone calls - sometimes asynchronous
+communication is actually /more/ productive.
+
+** The Light at the End of the Tunnel
+
+After initial setup (which typically takes 30-60 minutes), here's what
+you get:
+
+- ✅ A silent background process that automatically processes tasks
+- ✅ Complete privacy - no data ever leaves your machine
+- ✅ The ability to run state-of-the-art models without expensive
+  hardware.
+- ✅ A system that keeps working while you sleep - queue up 10 tasks
+  before bed, get results in the morning.
+
+You fill find that after the first few processed tasks, the initial
+setup effort feels worthwhile. You're not just getting another
+chatbot - you're building a personal AI workstation tailored to your
+specific needs. The initial investment pays dividends every time you
+need serious AI power without compromise.
+
+* Installation
+** Requirements
+*Operating System:*
+
+Älyverkko CLI is developed and tested on Debian 12 "Bookworm". It
+should work on any modern Linux distribution with minimal adjustments
+to the installation process.
+
+*Dependencies:*
+- Java Development Kit (JDK) 17 or higher
+- Apache Maven for building the project
+
+*Hardware Requirements:*
+- Modern multi-core CPU.
+- The more RAM you have, the smarter AI model you can use. For
+  example, at least 64 GB of RAM is needed to run decent AI models
+  with sufficiently large context.
+- Sufficient disk space to store large language models and
+  input/output data.

+Älyverkko CLI application configuration is done by editing YAML
+formatted configuration file.
+
+Configuration file should be placed under current user home directory:
+: ~/.config/alyverkko-cli.yaml
+
+*** Key Parameters Explained
+**** Core Directories
+
+- =mail_directory=: Where task files are placed for processing
+- =models_directory=: Contains GGUF model files
+- =skills_directory=: Contains YAML skill definition files
+- =llama_cli_path=: Path to llama.cpp's executable
+
+**** Generation Parameters
+
+- =default_temperature=: Creativity control (0-3, higher = more
+  creative)
+- =default_top_p=: Nucleus sampling threshold (0.0-1., higher = more
+  diverse)
+- =default_repeat_penalty=: Penalty for repetition (>0.0, 1.0 = no
+  penalty)
+
+**** Performance Tuning
+
+- =thread_count=: Sets the number of threads to be used by the AI
+  during response generation. RAM data transfer speed is usually
+  bottleneck here. When RAM bandwidth is saturated, increasing thread
+  count will no longer increase processing speed, but it will still
+  keep CPU cores unnecessarily busy.
+
+- =batch_thread_count=: Specifies the number of threads to use for
+  input prompt processing. CPU computing power is usually the
+  bottleneck here.
+
+**** Model-Specific Settings
+
+Each model in the =models= list can have:
+
+- =alias=: Short model alias. Model with alias "default" would be used
+  by default.
+
+- =filesystem_path=: File name of the model as located within
+  *models_directory*
+
+- =context_size_tokens=: Context size in tokens that model was trained
+  on.
+
+- =end_of_text_marker=: Some models produce certain markers to
+  indicate end of their output. If specified here, Älyverkko CLI can
+  identify and remove them so that they don't leak into
+  conversation. Default value is: *null*.
+
+- =temperature=, =top_p=, =repeat_penalty=: Model-specific overrides
+
+*** Configuration file example
+
+The application is configured using a YAML-formatted configuration
+file. Below is an example of how the configuration file might look:
+
+#+begin_src yaml
+  task_directory: "/home/user/AI/tasks"
+  models_directory: "/home/user/AI/models"
+  skills_directory: "/home/user/AI/skills"
+  llama_cli_path: "/home/user/AI/llama.cpp/build/bin/llama-cli"
+
+  # Processing parameters
+  default_temperature: 0.7
+  default_top_p: 0.9
+  default_repeat_penalty: 1.0
+  thread_count: 6
+  batch_thread_count: 10
+
+  # Model definitions
+  models:
+    - alias: "default"
+      filesystem_path: "model.gguf"
+      context_size_tokens: 64000
+      end_of_text_marker: null
+      temperature: 0.8     # Optional model-specific parameter

+      context_size_tokens: 32768
+      end_of_text_marker: null
+#+end_src
+
+*** Parameter Precedence Hierarchy
+
+For *temperature*, *top_p*, and *repeat_penalty* parameters, values
+are determined using this priority order (highest to lowest):
+
+1. *Skill-specific value* (from skill's YAML file)
+2. *Model-specific value* (from model configuration)
+3. *Global default value* (from main configuration)
+
+This allows fine-grained control where more specific configurations
+override broader ones.
+
+*** Enlisting available models
+Once Älyverkko CLI is installed and properly configured, you can run
+following command at commandline to see what models are available to
+it:
+
+: alyverkko-cli listmodels
+
+Note: Models that reference missing files will be automatically marked
+with "-missing" suffix in their alias by configuration wizard. You can
+manually remove this suffix after fixing the model file path.
+
+*** Self test
+The *selftest* command performs a series of checks to ensure the
+system is configured correctly:
+
+: alyverkko-cli selftest
+
+It verifies:
+- Configuration file integrity.
+- Model directory existence.
+- The presence of the *llama.cpp* executable.
+
+** Skill concept and configuration
+*** Skill File Format
+
+Skills are defined in YAML files stored in the *skills_directory*.
+
+Each skill file contains:

+** Starting process daemon
+
+Älyverkko CLI keeps continuously listening for and processing tasks
+from a specified mail directory.
+
+There are multiple alternative ways to start Älyverkko CLI in mail
+processing mode:
+
+**** Start via command line interface
+
+1. Open your terminal.
+
+2. Run the command:
+   : alyverkko-cli process
+
+3. The application will start monitoring the configured mail directory
+   for incoming messages and process them accordingly in endless loop.
+
+4. To terminate Älyverkko CLI, just hit *CTRL+c* on the keyboard, or
+   close terminal window.
+
+**** Start using your desktop environment application launcher
+
+1. Access the application launcher or application menu on your desktop
+   environment.
+
+2. Search for "Älyverkko CLI".
+
+3. Click on the icon to start the application. It will open its own
+   terminal.
+
+4. If you want to stop Älyverkko CLI, just close terminal window.
+
+**** Start in the background as systemd system service
+
+During Älyverkko CLI [[id:0b705a37-9b84-4cd5-878a-fedc9ab09b12][installation]], installation script will prompt you
+if you want to install *systemd* service. If you chose *Y*, Alyverkko
+CLI would be immediately started in the background as a system
+service. Also it will be automatically started on every system reboot.
+
+To view service status, use:
+: systemctl -l status alyverkko-cli
+
+If you want to stop or disable service, you can do so using systemd
+facilities:
+
+: sudo systemctl stop alyverkko-cli
+: sudo systemctl disable alyverkko-cli
+
+* Usage
+** Task file format
+
+Task files follow a specific structure that begins with a header line:
+
+#+begin_example
+TOCOMPUTE: [parameters]
+[User prompt content]
+#+end_example
+
+*** Task File Header Format
+
+The first line *must* begin with exactly =TOCOMPUTE:= followed by
+space-separated key-value pairs:
+
+#+begin_example
+TOCOMPUTE: skill=default model=mistral priority=10
+#+end_example
+
+Valid parameters in the header:
+- =skill=[name]=: Specifies which skill to use (defaults to "default")
+- =model=[alias]=: Specifies which AI model to use (defaults to "default")
+- =priority=[integer]=: Higher integers mean higher priority (default: 0)
+
+*** Processed File Format
+
+After AI processing completes, a new file is created with:
+1. First line: =DONE: skill=[name] model=[alias] duration=[time]=
+2. =* USER:= section containing original user prompt

+
+The Älyverkko CLI application expects input files for processing in
+the form of plain text files within the specified tasks directory
+(configured in the [[id:0fcdae48-81c5-4ae1-bdb9-64ae74e87c45][YAML configuration file]]).
+
+Suggested usage flow is to prepare AI assignments within the Älyverkko

+
+*** "joinfiles" command
+*Note:* See also alternative solution with similar goal: [[https://github.com/aerugo/prelude][prelude]].
+
+The *joinfiles* command is a utility for aggregating the contents of
+multiple files into a single document, which can then be processed by
+AI. This is particularly useful for preparing comprehensive problem
+statements from various source files, such as software project
+directories or collections of text documents.
+
+**** Usage
+
+To use the *joinfiles* command, specify the source directory
+containing the files you wish to join and a topic name that will be
+used to generate the output file name:
+
+#+begin_example
+alyverkko-cli joinfiles -s /path/to/source/directory -t "my_topic"
+#+end_example
+
+If desired, you can also specify a glob pattern to match only certain files within the directory:
+
+#+begin_example
+alyverkko-cli joinfiles -s /path/to/source/directory -p "*.java" -t "my_topic"
+#+end_example
+
+After joining the files, you can choose to open the resulting document
+in text editor for further editing or review:
+
+#+begin_example
+alyverkko-cli joinfiles -t "my_topic" --edit
+#+end_example
+
+**** Options
+
+- **-s, --src-dir**: Specifies the source directory from which to join
+  files.
+
+- **-p, --pattern**: An optional glob pattern to match specific files
+  within the source directory.
+
+- **-t, --topic**: The topic name that will be used as a basis for the
+  output file name and should reflect the subject matter of the joined
+  content.
+
+- **-e, --edit**: Opens the joined file in text editor after the join
+  operation is complete.
+
+**** Example Use Case
+
+Imagine you have a software project with various source files that you
+want to analyze using AI. You can use the *joinfiles* command to
+create a single document for processing:
+
+#+begin_example
+alyverkko-cli joinfiles -s /path/to/project -p "*.java" -t "software_analysis" --edit
+#+end_example
+
+This will recursively search the project directory for Java source
+files, aggregate their contents into a file named
+*software_analysis.org* (within AI processor input files directory),
+and open text editor on the file, so that you can add your analysis
+instructions or problem statement. Finally you [[id:883d6e7c-60e0-422b-8c00-5cdc9dfec20d][Initiate AI processing]]
+and after some time, you will get results and the end of the file.

+** Initiate AI processing
+:PROPERTIES:
+:ID:       883d6e7c-60e0-422b-8c00-5cdc9dfec20d
+:END:
+
+Once your task file is prepared, you should place *TOCOMPUTE:* marker
+on the first line of that file, so that it will be considered for
+processing.
+
+When the Älyverkko CLI detects a new or modified file in the mail
+directory:
+
+1. It checks if file has "TOCOMPUTE:" on the first line. If no, file
+   is ignored. Otherwise Älyverkko CLI continues processing the file.
+
+2. It reads the content of the file and feeds it as an input for an AI
+   model to generate a response.
+
+4. Once the AI has generated a response, the application appends this
+   response to the original mail contents within the same file, using
+   org-mode syntax to distinguish between the user's query and the
+   assistant's reply. The updated file will contain both the original
+   query (prefixed with: "* USER:*") and the AI's response (prefixed
+   with "* ASSISTANT:"), ensuring a clear and organized conversation
+   thread. "TOCOMPUTE:" is removed from the beginning of the file to
+   avoid processing same file again.
+
+Note: During AI task file preparation, feel free to save intermediary
+states as often as needed because AI engine will keep ignoring the
+file until *TOCOMPUTE:* line appears. Once AI assignment is ready, add
+: TOCOMPUTE:
+to the beginning of the file and save one last time. Älyverkko CLI
+will detect new task approximately within one second after file is
+saved and will start processing it.
+

+Note: GNU Emacs and following Emacs Lisp utilities are not required to

+GNU Emacs users.
+
+*** Easily compose new problem statement for AI from emacs
+
+The Elisp function *ai-new-topic* facilitates the creation and opening
+of a new Org-mode file dedicated to a user-defined topic within a
+specified directory. Now you can use this file within emacs to compose
+you problem statement to AI.
+
+When *ai-new-topic* function triggered, it first prompts the user to
+input a topic name. This name will serve as the basis for the filename
+and the title within the document.
+
+The function then constructs a file path by concatenating the
+pre-defined =alyverkko-topic-files-directory= (which should be set to
+your topics directory), the topic name, and the =.org= extension. If a
+file with this path does not already exist, the function will create a
+new file and open it for editing.

+
+The function =alyverkko-compute= is designed to enhance the workflow
+of users working with the Älyverkko CLI application by automating the
+process of marking text files for computation with a specific AI model
