Description
Back up ChatGPT, Claude, and Gemini chats to local Markdown, PDF, JSON, or HTML files. Nothing leaves your browser. Prompt Vault saves your AI chat conversations as local files so you own a durable, portable copy — no account, no cloud, no data leaving your browser. On a ChatGPT, Claude, or Gemini conversation page, export buttons appear in the header. One click saves the open conversation to your computer in the format you choose: • Markdown (.md) — clean, portable text with headings and code blocks preserved • PDF (.pdf) — selectable text, with Korean/CJK glyphs and monospace code blocks • JSON (.json) — structured, round-trippable data • HTML (.html) — a self-contained document you can open in any browser Need more than one conversation? Open the bulk-export panel, tick the conversations you want, and save the whole set in one format and one run. On ChatGPT and Claude you can do this from the sidebar, from a project's conversation list, or — on Claude — from the full history page at claude.ai/recents. Key points: • 100% local. The extension makes no network requests and sends nothing to any server. Your conversations never leave your browser. • Least privilege. It runs only on ChatGPT (chatgpt.com), Claude (claude.ai) and Gemini (gemini.google.com), and requests only the minimum permissions needed. • Fails loud, not short. When an export cannot be read, the extension shows an error instead of downloading a half-empty file. • Choose your toolbar. The extension popup lets you show or hide each export format icon and the bulk-export icon. • English and Korean UI follows your browser language. Supported providers: ChatGPT, Claude and Gemini. Bulk export is available on ChatGPT and Claude; Gemini supports single-conversation export.
