If ChatGPT is part of how you think, write, research, or plan, those conversations matter. Models change. Product decisions change. Your habits may change too. ChatKeeper helps you keep the useful work you’ve already done by turning your official ChatGPT export into readable local Markdown files.

Don’t Leave Your Best Conversations Trapped in One App

Some ChatGPT conversations are disposable. Others are not.

They contain research notes, draft writing, explanations that finally clicked, project plans, code experiments, personal insights, and lines of thought you may want to revisit later.

But ChatGPT is still a changing product. Models come and go. Tone shifts. Features move around. You may eventually switch tools, switch accounts, downgrade plans, or simply want a backup you control.

Your conversation history should not depend on any of that.


ChatKeeper Turns Your Export Into Files You Actually Own

ChatKeeper takes the official ChatGPT export from your personal account and converts it into clean, structured Markdown files on your computer.

That gives you a history you can:

No browser extension. No scraping. No third-party cloud service handling your chats. Just your export, converted into files you control.

Because a Raw Export is Not the Same as a Usable Archive

Obsidian view of a conversation explaining how to set up a blog using the Hugo static site generator. Obsidian view of a conversation with a silly birthday image. Obsidian view of a conversation containing a training plan rendered in a table.

Yes, you can export your ChatGPT data.

But the raw export is not a comfortable place to live. It is not designed to be a readable working archive for everyday use.

ChatKeeper makes that export useful by turning it into organized Markdown files that are far easier to browse, revisit, link, and integrate into your own system.

“People need to see how good your chat formatting is, the accurate timestamps, the numbered headers, the note index feature, and also how you elegantly contained any messy output from the tool call like audio, canvas documents, etc” - Actual Customer

How It Works

ChatKeeper works with the official ChatGPT export file from supported personal ChatGPT plans (Free, Personal, and Plus). It’s not a browser plugin and not a scraper. Just a simple, local application on your computer.

  1. Export your data from ChatGPT
  2. Open the export in ChatKeeper
  3. Generate a local archive of structured Markdown files
  4. Keep it, search it, back it up, and use it however you like

Even if ChatGPT Changes, Your Past Conversations Can Still Matter

Maybe you miss an older model. Maybe the tone feels different now. Maybe you are trying other tools. Maybe you just want less dependence on a single interface.

Whatever the reason, preserving your history is still worthwhile.

ChatKeeper does not try to preserve a model itself. It preserves the work you did with it.


Keep Your History While It’s Still Yours to Organize

If ChatGPT has been part of your workflow, your learning, or your thinking, don’t leave that history stranded in a changing product.
