ChatKeeper 1.2.2
May 19, 2025
🤕 Heads up as of June 22, 2026
You probably don’t want the version below and should download this version instead.
OpenAI recently changed the ChatGPT export format, which can cause errors in the latest official ChatKeeper release. An Adventure Build that eliminates these errors is available now. Additional work is in progress to handle other changes in the format. Stay tuned!
Send me an email for a one-time notification when a new official release is ready.
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
