I built a free extension to save your AI conversations locally — exports to Markdown, PDF, JSON and more
Ever have a 200-message deep-dive with ChatGPT on a complex topic, then panic about losing it? Copy-pasting doesn't scale, and ChatGPT's built-in export is buried and slow.
I built ChatArchive to fix this. One click and it scrolls through your entire conversation history and saves it as a clean local file — no account, no backend, nothing leaves your browser.
Formats: Markdown, Obsidian Markdown, PDF, HTML, plain text, JSON, CSV
Also works on: Gemini, Claude, Perplexity, Grok, DeepSeek, and 7 more
A few things that make it different from other exporters:
- Each platform has its own adapter, so when a site updates its UI, only that adapter breaks — not everything
- The popup shows you exactly how the extraction worked (source, strategy, confidence, message count)
- Custom filename templates so your exports are actually organized
- Stop & Save shortcut if you need to bail out of a long export early
It's open source on GitHub if you want to poke around or contribute.

Happy to answer questions or take feedback — especially if it breaks on a platform you use.
