Chat Archive Viewer

Your old chats, back in one list. Chat Archive Viewer opens the data export you download from ChatGPT or Claude and turns it into a fast, private archive you can browse by month, search, and save. Works with ChatGPT and Claude data exports. Not affiliated with, endorsed by, or sponsored by OpenAI or Anthropic. WHY - Browse every chat by month, newest first, with a jump-to-month menu. No more scrolling a sidebar or guessing search words. - Search the full text of every message, not just titles. - Save any chat as Markdown or print it to PDF. The print layout includes the whole conversation, start to finish. - Huge exports are fine. The file is read in small pieces in the background, so an 850 MB export does not freeze or crash the tab. - Edited prompts and regenerated replies are handled: you see the version you kept, like in the app. - Code blocks keep their language and have a copy button. Tool calls, file attachments and image prompts are shown, not dropped. PRIVATE BY DESIGN - Nothing leaves your device. The extension has no access to any website and asks for no site permissions. - It never reads chatgpt.com or claude.ai and never logs in anywhere. It only reads the export file you choose. - Your archive is stored in this browser only. "Clear archive" removes it, and uninstalling removes it too. HOW TO GET YOUR EXPORT - ChatGPT: Settings > Data controls > Export data. OpenAI emails a download link. - Claude: Settings > Privacy > Export data. Anthropic emails a download link. - Open the ZIP here (no need to unzip). conversations.json works too. FREE AND PRO - Free: open, search and save your newest 100 chats. No account needed. - Pro, $12 one-time: every chat, search across everything, export your whole archive as Markdown files, and export an Obsidian vault with front matter and a month index. - Payments are handled by ExtensionPay and Stripe. Payment status is the only thing the extension ever checks online. ChatGPT is a trademark of OpenAI. Claude is a trademark of Anthropic. They are named here only to say which export files this tool can open.
