ThreadPort

About ThreadPort

ThreadPort is a browser extension for Chrome and Edge that moves an active AI chat between ChatGPT, Claude, and Gemini in one click. It extracts the conversation you're currently in, cleans out UI elements like widgets and buttons, and pastes it into another AI service with context intact. The tool runs entirely in the browser with no servers and no account required.

Review

ThreadPort launched this week and addresses a specific workflow problem for people who switch between multiple AI assistants. Each service has its own strengths and rate limits, but copying conversations manually often loses formatting and context. This extension automates that transfer.

Key Features

• One-click transfer of the active chat to another AI service, preserving the full conversation thread as context
• DOM-based extraction that strips out UI clutter such as buttons, citations, and widgets before pasting
• No server-side processing; all data stays in the browser, which also means it's operational in the EU
• Free tier allows 10 transfers per month with no account or tracking
• Works as a browser extension on both Chrome and Edge

Pricing and Value

The extension is free for 10 transfers per month. The maker has not defined a paid tier or stated pricing beyond that free allocation. There's no subscription or account creation required for the free tier, and the extension doesn't rely on any server infrastructure that could incur ongoing costs for its operation.

Pros

• Removes the friction of manual copy-paste across AI chat interfaces.
• Preserves conversation context, which matters for follow-up questions.
• Runs without servers or accounts, keeping user data in the local browser.
• EU availability where some native AI import tools are unsupported.
• Built with Claude Code, which the maker credits for the extraction strategies and debugging.

Cons

• Depends on page layouts; the maker acknowledges that a site redesign can break the extension until a fix ships.
• The 10-transfer monthly cap may feel restrictive for daily users who bounce between multiple AIs.
• Not for people who use Safari, Firefox, or desktop apps, since the extension targets only Chromium browsers.

ThreadPort suits frequent users of ChatGPT, Claude, or Gemini who need an occasional conversation carried over when switching tools. It's also a parent choice for those in the EU where certain native import options are unavailable. For anyone requiring high-volume transfers or non-Chromium support, it doesn't fit yet, though the maker has stated Firefox is a possible next step.
