AI Chat Archive：Claude のチャットを PDF、Markdown、HTML で書 作成者: windam

Save your Claude.ai and ChatGPT conversations, and entire Claude projects, as PDF, Markdown, HTML, JSON, or plain text — locally on your device. Single chat with one click, an entire Claude.ai project (Instructions, knowledge files, every conversation inside) packaged as a ZIP, or batch-archive your whole history.

Runs entirely in your browser. Conversations never touch our servers. The extension talks only to claude.ai — and chatgpt.com once you enable it — using your existing session cookie, the same API the web app uses, and writes the result straight to your Downloads folder.

━━━━━━━━━━ WHY USE THIS ━━━━━━━━━━

• Unlimited local PDF — no server, no cap, no quota
• Claude AND ChatGPT — one tool for both assistants, including chats inside ChatGPT Projects and custom GPTs (Gemini on the roadmap)
• Export entire Claude.ai projects — Instructions, knowledge docs (text + binary uploads), and every conversation inside, all in one ZIP
• Export Claude Cowork tasks — the agentic claude.ai/cowork/ surface: full transcript free in every format, with the task's output files bundled into the ZIP on paid plans
• Local-first: zero servers, zero accounts, zero telemetry
• Real Markdown output — lists render as lists, code blocks as code blocks
• PDF with proper CJK font support out of the box
• Multi-format from a single export: same chat, five outputs
• Open-source console scripts available for users who'd rather not install

━━━━━━━━━━ FREE ━━━━━━━━━━

• Single-conversation export in Markdown, JSON, TXT, HTML, or PDF — for both Claude and ChatGPT
• Real Markdown lists, code blocks, proper CJK font support in PDF output
• Unlimited local PDF exports — no daily cap
• Images embedded in HTML and PDF — pictures you uploaded and ones the AI generated
• Export via popup, or via a floating button that appears on every claude.ai and chatgpt.com chat

━━━━━━━━ PAID (one-time or subscription) ━━━━━━━━

• Project export — pack an entire Claude.ai project (Instructions, knowledge files, every chat inside, optional per-chat attachments) as one ZIP
• Batch export — your entire Claude or ChatGPT history as one ZIP
• Attachment bundling — uploaded files, AI-generated docx/xlsx/py, images bundled into the ZIP (Claude and ChatGPT)

━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━

1. Install, open any conversation at claude.ai/chat/… (or a project page at claude.ai/project/…)
2. Click the orange "Export" button in the top-right corner (or the toolbar icon)
3. Pick a format, optionally toggle "Include attachments" if you're on the paid tier, and export

To export from ChatGPT, open the extension popup once and click "Enable on ChatGPT" to grant access to chatgpt.com — the same Export button then appears on your chatgpt.com chats.

Exports land in your Downloads folder. No account needed, no sign-in, no email collected.

━━━━━━━━━━ PRIVACY ━━━━━━━━━━

The extension makes network calls to these hosts only:

• claude.ai — to read your own conversations with your existing session cookie
• chatgpt.com — the same, and only after you opt in via "Enable on ChatGPT"
• api.polar.sh — to validate your license key for paid features (sends only the key, nothing else)

No analytics, no telemetry, no personal data sent to us. All preferences are stored in your browser's local extension storage. Full privacy policy at aichatarchive.app/privacy.

━━━━━━━━━━ COMPATIBILITY ━━━━━━━━━━

Works in Chrome, Edge, Brave, Arc, and other Chromium browsers, exporting both claude.ai and chatgpt.com. Firefox and Safari builds are also available. Gemini support on the roadmap.
