ChatGPT Thread Toolkit

ChatGPT Thread Toolkit is a focused Chrome extension for long ChatGPT conversations. It adds a small floating action menu inside supported ChatGPT threads so you can: - compact older heavy turns while keeping recent context visible, - enable per-chat auto-collapse for specific conversation URLs, - export the full current conversation as Markdown, - export the same conversation as JSONL with only `role` and `text`. The extension is intentionally lightweight. It does not add a second complex UI layer on top of ChatGPT. The toolbar popup only confirms whether the current tab is supported and points the user back to the in-page floating menu. All processing stays local in the browser. No chat content is uploaded anywhere, and the extension does not include analytics, telemetry, or third-party services.
