Feroとは
Move chats from ChatGPT, Claude, Gemini or Copilot to another AI in 2 clicks. Usage tracker + code-aware summaries to save tokens. Move a conversation from one AI to another in two clicks. Fero captures your current chat with ChatGPT, Claude, Gemini, or Copilot and sends it straight into a different assistant — cleanly formatted, so you never lose context when you switch.
Send to any AI:
- One click opens the destination AI and places your chat in its message box — you review it and press send yourself.
- Large chats are attached automatically as a file, so nothing lags or freezes.
- Hit a usage limit or the conversation length wall? Continue in a fresh chat or a different AI without losing context.
Three ways to copy your chat:
- Transcript — the whole conversation, word for word.
- Condensed — shorter, but keeps all the context.
- Smart — a short summary of the main points, generated on-device by Chrome's built-in AI (Gemini Nano).
- Made for code-heavy chats: Code mode extracts and dedupes pasted code, so summaries stay small and save tokens.
Built for privacy:

- 100% local — everything runs in your browser; nothing is uploaded, tracked, or sent to any server.
- On-device AI — Condensed and Smart use Chrome's built-in Gemini Nano, so your conversation never leaves your machine.
- Secret-safe — Fero automatically hides API keys, tokens, and passwords behind placeholders before your chat goes anywhere. Reveal them only when you choose.
- Condensed and Smart mode only work in the Chrome browser.
Also: a fit meter shows how big the copy is (token size) for the destination, a usage card shows how much of your Claude/Gemini limit is left, export any chat as a Markdown file, and your capture history is stored locally.
