This tool helps you manage large amounts of data for your AI models. It packs your files into a format that Claude Opus 4.8, Fable 5, and Mythos 5 understand. By doing this, you fit more information into the context window of these models. This lets the AI perform better on complex tasks without losing track of your project details.
You use this tool to remove extra data that clutters your work. It organizes your code dependencies so the AI spends less time reading junk and more time thinking about your requests.
Your computer needs to meet these basic standards to run the software.
- Windows 10 or Windows 11.
- At least 4GB of free memory space.
- An active internet connection for model communication.
- Sufficient disk space to hold your project files.
You can get the application from the project page. Visit the link below to reach the latest version.

- Once the bar reaches the end, the tool saves the optimized file to your desktop.
The tool organizes your project files into a single, clean text block. It removes characters that serve no purpose for the AI. It also maps out your dependency tree, which is a list of how your code parts relate to one another. By listing these relations first, the AI learns the structure of your project before it tries to solve problems. This saves memory and prevents the AI from becoming confused by large input sizes.
- Keep your file names clear and simple.
- Avoid packing very large image files or binary assets.
- Run the tool every time you make major changes to your project.
- Check the output folder to ensure all relevant files fit within the allowed limit.
What should I do if the tool stops working? Close the application fully and restart your computer. Then, try the process again. If the problem persists, check that you have the latest version installed from the link provided above.
Does the tool send my data to a server? The tool processes your files locally on your computer. It does not upload your project files to the internet during the packing process.
Can I use this for projects other than code? Yes. Although designed for code, it works with most text-based files.
Does this work with my AI account? This tool prepares the text for your AI provider. You still need your own account or API key to interact with Claude, Fable, or Mythos.
How do I clear the cached data? The application clears its temporary workspace automatically when you close the program. You do not need to delete anything manually.
