March 22, 2026

By downloading ChatKeeper, you are agreeing to its Terms of Service and EULA. It’s a quick read and (I believe) a reasonable policy, but it’s important that we start on the same page.

You can try ChatKeeper for free without providing your name, email, credit card, or anything else. If you don’t have a license, there will be some limitations as described here.

Already have ChatKeeper and just want your "Forever License"?

This is the first production ChatKeeper release with signed installers for Windows and macOS users. Signed installers help ensure that you’re installing exactly what you think you’re installing. This means a quicker, easier, and much smoother path from downloading to actually using the software and owning your conversations.

ChatKeeper’s new GUI is installed alongside the same Command Line Interface (CLI) that you’re familiar with. The GUI can can do everything the CLI can do, and the CLI remains included and fully supported.

Key Features

• Full Desktop GUI using the same proven sync engine as the CLI
• Signed desktop installers for Windows and macOS
• RPM and DEB packages for Linux
• Drag-and-drop support for ChatGPT export ZIP files
• Guided syncing workflow with clear, step-by-step options
• Support for ChatGPT’s new (February 2026) export format
  • Handles new conversations-000.json, conversations-001.json, etc.
  • Original conversations.json still supported.
• Automatic PATH integration so chatkeeper works from any terminal

Known Issues

Update as of June 9, 2026: OpenAI recently changed the ChatGPT export format, which can cause errors in this and in earlier releases. The current Adventure Build includes support for this change.
