About Ctxport
Ctxport is a free, open-source Chrome extension that copies conversations from ChatGPT, Claude, Gemini, DeepSeek, Grok, Doubao, and GitHub Copilot into clean, structured Markdown with YAML frontmatter. It solves the pain of broken HTML, lost formatting, and manual copying when moving context between AI tools or archiving chats. The extension adds a copy button inside each chat interface and a sidebar list for batch copying without opening conversations. A keyboard shortcut (Alt+Shift+C) provides instant access. All processing happens locally in the browser – no data upload, no account, no telemetry. Export formats include Full (frontmatter + all messages), User Only (user messages), Code Only (fenced code blocks), and Compact (messages without metadata). Code blocks retain language tags and indentation. Installation requires manual sideloading from a ZIP file; there is no Chrome Web Store listing. Ctxport is MIT-licensed on GitHub. For privacy-conscious power users who frequently switch AI platforms, it offers a lightweight alternative to cloud-based conversation managers – everything stays on your machine.
Behind the Verdict
For anyone who regularly copies AI conversations to move context or archive them, Ctxport is a game-changer in the best sense – it just works. We'd reach for this when switching between ChatGPT and Claude mid-project, or when capturing a long debugging session for later reference. When to pass? If you need a mobile app, cloud sync, or team collaboration, this isn't for you. It's also Chrome-only for now, and installation requires developer mode, which may deter less technical users. Compared to alternatives like browser bookmarklets or manual copy-paste, Ctxport wins on speed and consistency. Unlike cloud-based tools that upload your data, it keeps everything local – a strong advantage for privacy-sensitive workflows. Where it bites: the lack of an official store listing means no automatic updates. You'll need to manually download new versions from GitHub. Also, it only copies from supported platforms – not from arbitrary web UIs. In practice, the sidebar copy feature is the standout: grab any past conversation without opening it. For users managing dozens of chats, that alone is worth the install hassle. Verdict: best for solo devs, researchers, and writers who want a free, private, and efficient way to port AI conversations. Teams and mobile users should look elsewhere.
