ChatGPT, Claude and Gemini all let you download your conversations, but the files are built for machines: deeply nested JSON, split archives, activity logs. This tool turns them back into readable conversations and into formats you can keep.
Everything runs locally in your browser. The export is read in a background thread, images are pulled from the ZIP only when you open a chat, and nothing is sent anywhere.
Supported exports
- ChatGPT: the data export ZIP (
conversations.jsonor splitconversations-000.jsonfiles), orchat.htmlon its own. - Claude: the single-ZIP export and the newer manifest + multi-ZIP export.
- Gemini: Google Takeout My Activity in JSON format (experimental).
