I found an easier way to transfer my chats between ChatGPT, Claude and Gemini - and it only takes a single Chrome extension

A Chrome extension called ThreadPort lets users transfer full chat transcripts between ChatGPT, Claude, and Gemini, with the developer stating that chats are not stored on their servers. The extension, which preserves conversation context and task, was tested by a Tom's Guide writer in a research session on the video game industry's next console cycle.

A Workflow Problem

As AI assistants become increasingly similar, switching between them often comes down to small differences in speed, integrations, or output quality. One approach is to start a research-themed chat in one tool, move it to another, and then a third, to get multiple perspectives on the same question. Until recently, that meant a lot of copying and pasting.

For some users, the appeal of mixing AI tools lies in their strengths and weaknesses. ChatGPT's response time is fast, and it's good for creative brainstorming, but it is more prone to hallucinations. Claude is strong for lengthy document analysis and its writing reads as more human-like, but its usage limits are tight for free users. Gemini, Google's chatbot, relies on real-time web research that cites up-to-date information and integrates with Google Workspace, yet it too can hallucinate and struggles with complex prompts.

ThreadPort: One Extension to Transfer Chats

A Chrome extension called ThreadPort aims to simplify this workflow. According to a Tom's Guide writer who tested it, ThreadPort moves the full transcript of a conversation between ChatGPT, Claude, and Gemini, rather than summarizing it. The developer stated that transferred chats are never stored on their servers. The extension can handle conversations of any length and retains the chat's defined task.

In a test described by the author, ThreadPort was used during a research session about the video game industry's next console cycle. The extension pasted a specific instruction into the receiving AI: 'You are continuing a conversation that started on ChatGPT. Below is the transcript so far. Absorb it as context and continue the conversation naturally — do not summarize it back to me, just pick up where I left off.'

Claude responded with 'Good context to draw from. Now let me continue the conversation naturally...' Gemini responded with 'The structural cracks in the business model point to a console cycle that could be harsher...'

ThreadPort currently supports ChatGPT, Claude, and Gemini. The author hopes Perplexity and Kimi will be added in the future.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
