Download ChatKeeper
By downloading ChatKeeper, you are agreeing to our Terms of Service and EULA. It’s a quick read and (we 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 purchase a license, there will be some limitations as described here.
ChatKeeper is a standalone executable. That means you don’t need to install it - just download and run (although you might want to put it somewhere in your path).
ChatKeeper 1.2.2 - May 19, 2025
Work continues on the GUI version of ChatKeeper, but in the meantime I have an update for you.
Version 1.2.2 now produces markdown for ChatGPT’s “Chain of Thought”. This is the text that you might see flashing by while it’s “Reasoning”, followed by something like “Thought for 15 seconds.”
In your markdown, it might render something like this:
Before this release, any conversations containing Chain of Thought would result in some (harmless) warnings about unhandled message types thoughts and reasoning_recap.
Other Stuff
There are a few other minor tweaks, too:
- The format for “canvas” conversations was updated by OpenAI. ChatKeeper can now handle them properly again.
- Some more unwanted console messages were removed (oops)
- A very strange NullPointerException error that was preventing ChatKeeper from running for one user was hopefully fixed. (I say “hopefully” because I was not able to reproduce the issue and I have not yet heard back whether an early release candidate resolved the problem for them.)
This version continues to build on all the great new features of 1.2.0:
- Exporting Generated Images
- Handling Unzipped Exports (e.g., when Safari “helpfully” unzips downloads automatically)
- Support for Tasks.
- Lots of smaller stuff
