Show HN: I lost 3 years of ChatGPT history overnight, so I built a backup tool

One month ago, OpenAI deactivated my ChatGPT account without warning. 3+ years of conversations—gone.

I tried everything. Emailed every OpenAI address I could find. Their response? "Use our data export tool." The catch? You need an active account to export your data.

Classic.

So I built a browser extension that lets me save any conversation from ChatGPT, Claude, or Gemini with one click. Markdown format, stored in one place.

Turns out it solved another problem I didn't expect: I often ask the same question to all three AIs, then forget which one gave me the best answer. Now they're all in one place.

It's been my personal tool for now. Nothing fancy—just scratching my own itch. If there's interest, I'll consider publishing it. Could easily extend to other AI assistants too.

Anyone else paranoid about their AI chat history now?
