Hi HN, I’m rock, the creator of this extension. I frequently use Claude and ChatGPT for coding and research, but always found it painful to clean, save, or share these chats with colleagues without cluttering. So I built this to render clean documents.

Unlike online PDF converters, it does not send your chats to any backend server. Everything is rendered 100% locally in your browser to preserve privacy.

It’s built with Vanilla JS. One challenge was handling the custom markdown formats of different AI platforms (e.g., math blocks in ChatGPT, nested code structures in Claude). I had to write custom parsers for each AI platforms.

Let me know what you think.
