A modern file viewer application for developers to easily navigate, search, and copy code from repositories.
Ideal for pasting into ChatGPT or your LLM of choice. Built with Electron, React, and TypeScript.

PasteMax is a simple desktop app built for developers using AI coding assistants. It makes sharing your code with LLMs easy, thanks to a smart file explorer with token counting, file filtering, quick copy, and a previewer. Select the files you need, skip binaries and junk, and get clean, formatted snippets ready for your LLM.

If you see a warning about the app not being trusted, you can bypass this by clicking "run anyways". This is a common issue with Electron apps, especially since PasteMax is not signed.

If you encounter an "App not responding" message on Mac, it may be due to macOS security settings. You can try the following:

1. Open System Preferences.
2. Go to Security & Privacy.
3. Under the General tab, look for the "Allow apps downloaded from" section.
4. Look for "PasteMax" and click "Open Anyway".

If you encounter other issues, please report them on GitHub.
