AI Chat Archive: Export Claude & ChatGPT Chats to PDF, Markdown

Save any Claude or ChatGPT conversation as a PDF, Markdown, HTML, JSON, or plain-text file. One extension covers both assistants, and single-chat exports are free and unlimited in every format. The PDF is rendered by your own browser, so there is no daily quota and nothing is uploaded to a conversion service. The extension reads the conversation from the claude.ai or chatgpt.com session you are already signed in to. For PDF it opens your browser's print dialog with the export laid out and ready — you pick "Save as PDF" and choose where it goes. Markdown, HTML, JSON, and TXT download like any other file, wherever your browser puts downloads. ━━━━━━━━━━ FREE — CLAUDE AND CHATGPT ━━━━━━━━━━ • Unlimited single-chat PDF, generated locally — no daily cap, no server • The same conversation as Markdown, HTML, JSON, or TXT • Obsidian-ready Markdown: real lists, real code blocks, optional YAML front matter • Images embedded in HTML and PDF — the ones you uploaded and the ones the AI generated • CJK fonts render correctly in PDF out of the box • Covers ChatGPT chats inside Projects and custom GPTs, and Claude Cowork tasks • Export from the toolbar popup, or from the floating "Export" button on the page ━━━━━━━━ PAID ━━━━━━━━ • Claude project export — one ZIP with the project's Instructions, knowledge files, and every conversation inside it • Batch export — your whole Claude or ChatGPT chat history as a single ZIP • Attachment bundling — files you uploaded and files the AI produced, packed into the ZIP • No branding footer on exported files Project and batch ZIPs use Markdown, HTML, JSON, or TXT; PDF is for single conversations.

For chat access and license validation: • Claude and ChatGPT — the extension reads your own conversations through your existing session, using the same APIs their web apps use, and downloads your attachments and AI-generated files from the file storage those services point it to • Polar (api.polar.sh) — validates your paid license key without receiving any conversation content Using the extension involves no analytics, no telemetry, and no separate AI Chat Archive account to sign in to. Your settings are kept in browser extension storage, and your license key is stored so that it can travel between your browsers through your browser's own sync feature.
