ChatVault — Export ChatGPT & Claude Chats

ChatVault saves your ChatGPT and Claude conversations as real files on your computer — in one click. Copy-paste mangles formatting. "Save page as HTML" captures a fragment, because these sites only render the messages currently scrolled into view. ChatVault reads the conversation the same way the web app itself does, so you get the whole thing: every message, in order, with formatting intact. ━━━━━━━━━━━━━━━━━━━━ WHAT IT DOES ━━━━━━━━━━━━━━━━━━━━ • Export the conversation you're reading, in one click • Bulk export your entire chat history to a single .zip • Four formats: Markdown (.md), HTML (.html), JSON (.json), plain text (.txt) • Optionally include reasoning / thinking blocks • Optionally include tool calls and their results • Keeps code blocks, bold and lists intact • Artifacts are exported as proper code blocks • Claude attachments are included as filename plus extracted text (not the original file). ChatGPT attachments and images are not exported — images appear as a placeholder. • Files are named by date and title, so they sort sensibly ━━━━━━━━━━━━━━━━━━━━ WORKS WITH ━━━━━━━━━━━━━━━━━━━━ • Claude — claude.ai • ChatGPT — chatgpt.com ━━━━━━━━━━━━━━━━━━━━ WANT A PDF? ━━━━━━━━━━━━━━━━━━━━ Export as HTML and open the file, then print to PDF (Cmd/Ctrl + P). The HTML is styled for printing, works offline forever, and needs no internet connection — it's a single self-contained file with no external fonts, scripts or images. ━━━━━━━━━━━━━━━━━━━━ PRIVACY — THE SHORT VERSION ━━━━━━━━━━━━━━━━━━━━ Your conversations never leave your computer. • No servers. ChatVault has no backend of its own. • No account, no sign-up, no licence key. • No analytics, no telemetry, no tracking, no ads. • No third-party libraries and no remote code. To export a conversation, ChatVault necessarily reads that conversation — your messages, and the session token the site itself uses to authenticate you. Chrome classifies that as handling personal communications, authentication information and website content, and we disclose it rather than pretend otherwise. All of it stays on your machine: the only servers contacted are claude.ai and chatgpt.com, the same ones your browser already talks to, and the export is written straight to your disk. The extension talks to exactly two places: claude.ai and chatgpt.com — the sites you are already signed in to. It reads your own conversations using your own existing session, converts them in the browser, and hands the file to Chrome's downloader. That is the entire data path. Permissions requested: • "downloads" — to save the exported file • "storage" — to remember which format you picked • access to claude.ai and chatgpt.com — to read the conversations you ask it to export. No other site is accessible to this extension. ━━━━━━━━━━━━━━━━━━━━ GOOD FOR ━━━━━━━━━━━━━━━━━━━━ • Archiving research and long problem-solving threads • Getting chats into Obsidian, Notion, Logseq or a git repo • Keeping a record before you delete a chat or close an account • Sharing a clean transcript with a colleague or client • Backing up everything before you switch plans or providers Free, with no paid tier and no upsell.
