ChatExport AI - Gemini・Claude・ChatGPTをPDFなどに書き出し

ChatGPT、Claude、Gemini、DeepSeekなど10以上のAIプラットフォームの会話を、PDF、Wordをはじめ全11形式でエクスポート。

Your best AI work shouldn't be trapped in a chat window. ChatExport AI is the only Chrome extension that exports conversations from ChatGPT, Claude, and Gemini — all three major AI platforms, in a single tool, with one click. OTHER TOOLS COVER ONE PLATFORM. WE COVER ALL THREE. Most AI export tools are built for ChatGPT and ignore the rest. ChatExport AI works natively on all three major AI assistants and detects which platform you're on automatically. No switching tools, no configuration, ever. • ChatGPT (chatgpt.com) — all models, full message history, code blocks, tables, images • Claude (claude.ai) — including long research threads, analyses, and AI-generated artifacts • Gemini (gemini.google.com) — including rich responses with images and embedded media 10 EXPORT FORMATS — MORE THAN ANY OTHER AI EXPORTER Choose the format that fits your workflow: • Plain Text (.txt) — paste anywhere, universal compatibility • Markdown (.md) — drops straight into Obsidian, Notion, Bear, or GitHub. Syntax perfectly preserved. • JSON (.json) — structured data, developer-ready, pipeline-friendly • CSV (.csv) — import directly into spreadsheets or data tools • HTML (.html) — a styled, self-contained, shareable webpage • PDF (.pdf) — professional, print-ready documents • Word (.docx) — edit in Microsoft Word or Google Docs • Excel (.xlsx) — tabular data for analysis and reporting • Screenshot (.png) — a pixel-perfect visual snapshot of your conversation • ZIP Archive (.zip) — the full conversation bundled with every attachment and file EXPORT ENTIRE AI PROJECTS (PRO EXCLUSIVE) ChatGPT and Claude let you organise your work into Projects. No other exporter on the Chrome Web Store can touch them. ChatExport AI Pro fetches every conversation in a project, downloads every attachment and AI-generated artifact (code, documents, files), and packages everything into one clean, labelled ZIP archive — automatically, in one click. CHERRY-PICK EXACTLY WHAT YOU EXPORT Long conversations have noise. ChatExport AI adds a checkbox to every message so you can pick exactly which ones to include — the final answer, a specific exchange, or just the parts worth keeping. Select all, deselect a few, or hand-pick precisely what matters. Then export only that. No other AI export extension gives you this level of per-message control. BUILT FOR PRIVACY — ZERO COMPROMISE Your conversation content never leaves your browser. Every export — PDF, Word, Markdown, Screenshot — is generated entirely within your browser using bundled libraries. Nothing is uploaded or processed remotely. Not even temporarily. • No analytics. No telemetry. No crash reporting. • No cookies. No cross-site tracking. • Zero conversation data sent to any server, ever. • The only external request is Pro license validation, which sends only an encrypted device fingerprint — never your chat content. FREE PLAN The free plan includes all 10 export formats, works on all three AI platforms, and requires no account. The only limit is 3 exports per day, resetting at midnight.
