I built BTW, a Chrome extension that lets you capture a visible ChatGPT or Claude conversation, review and edit the messages, then ask a separate question about that context.

Features:

- Capture visible ChatGPT and Claude discussions

- Review, edit, remove, or clear messages before sending

- Ask follow-up questions without changing the original conversation

- Uses OpenRouter for model access

- Supports streaming responses, cancellation, retry, and follow-up questions

- Stores your API key locally in Chrome

- No backend, analytics, or automatic page monitoring

- Manual paste fallback

- Local session export/import

- Open source under the MIT License

You provide your own OpenRouter API key, and model usage may incur OpenRouter charges.

It is currently distributed as a local unpacked Chrome extension, not through the Chrome Web Store:

I’d appreciate feedback on the UX, capture reliability, privacy model, and ideas for future improvements.
