ChatKeeper 2026.10.002

October 11, 2026

TL/DR: The recent ChatGPT export compatibility updates and incomplete-export warnings are now in a full release.

This full release includes all compatibility work from recent Adventure Builds, which helps ChatKeeper handle ChatGPT’s changing export format. It also includes the warning introduced in September when an export looks incomplete, plus a new warning before resyncing all conversations from one of those exports.

What I mean by “incomplete export”

I’ve been having an issue with my ChatGPT exports for several months, and I’m not the only one.

My export files suddenly became much smaller (as in, hundreds of MB smaller). The reason is that they are missing a lot of information they used to contain, including things like generated images and even entire conversation turns.

Searching online has shown that others are experiencing it too. And, for some reason, it may not affect everybody. But in my case at least, it seems to be consistent: once my exports started dropping information, they continued to do so.

I’ve tried contacting OpenAI support multiple times about this. A few conversations and support tickets have started out encouragingly, but so far none have led anywhere. I’m still pursuing it; if you know someone at OpenAI who might be able to help me dig into this or put me in contact with someone who can, please point them my way!

In the meantime, ChatKeeper can detect signs of this issue and warn you before processing your export. You can choose to process it anyway.

Note that this release cannot recover content missing from the export. I recommend you keep your older exports around in case you need them later.

I’m very interested to hear what ChatKeeper reports to you. Whether you get the warning or not, please let me know with a quick message. As you might know, I don’t build any telemetry into my software. That’s really important to me for your privacy, but it also means I need to ask for help in situations like this.

I’m also looking into ways for ChatKeeper to safely preserve information from earlier exports when newer exports are missing it. That will require some fairly significant changes behind the scenes, but they should also make ChatKeeper’s internal handling of exports more robust in general.

Included since the previous full release

Added compatibility updates for newer ChatGPT exports, including canvases, web search results, generated images, citations, research status, and memory updates when that information is present in the export.
Added detection of signs of incomplete ChatGPT exports, with a warning in both the GUI and CLI.
Added a CLI option, --allow-incomplete, to explicitly bypass the warning and continue when running chatkeeper keep.
Added a warning to the GUI when “Resync All Conversations” is selected for an export file that may be missing information, because resyncing may remove information from previously exported conversations. This warning is new since the September Adventure Build.

Still in progress

Continuing to pursue the missing-data issue with OpenAI.
Developing a safe way to preserve previously exported information when later exports are incomplete.
