ChatKeeper 2026.06.001-adventure (Adventure Build)
June 4, 2026
🤕 Heads up as of September 27, 2026
I recommend downloading ChatKeeper 2026.09.011-adventure instead of the version below.
Earlier releases can encounter errors with newer ChatGPT export formats. This Adventure Build includes the compatibility updates and adds a warning when ChatKeeper detects signs of an incomplete export.
Some ChatGPT exports are missing generated images and even entire conversation turns. This release cannot recover content missing from the export, so it would be wise to keep your older exports around. See the release notes for details and how you can help.
And feel free to send me an email for a one-time notification when a new official release is ready!
Already have ChatKeeper and just want your "Forever License"?
ChatGPT’s export format has changed once again. The most recent changes impact the internal structure of the export json, resulting in excessive ChatKeeper warnings about unhandled message types and full-blown errors about a data field that is now null (not set at all) in the import.
There may be other changes in the new format, and I’m still looking into it in detail. But this update will let you keep working in the meantime!
Fixed and Added in This Release:
- Eliminated excessive warnings about unhandled message types
- Fixed an error due to null field in export
Still In Progress
- Fully examining export format changes
Known Issues (working on them now)
- Citation format appears to have changed and may not render correctly.
