Foldif

Folders, highlights & notes for ChatGPT, Claude and Gemini

Visit

Your best AI answers are buried in hundreds of chats. Foldif is a Chrome extension that turns chat history from a feed into a library you own — one extension for ChatGPT, Claude, and Gemini. Organize conversations into folders, highlight what matters, add margin notes, and compile months of insights into a real, exportable book. Local-first and privacy-friendly: your conversations never leave your browser. No API key, no signup wall, free core features.

The local-first privacy approach stands out most AI tools send everything to the cloud by default. The breadth of features is impressive but the real differentiator is keeping conversations in the browser with no signup. Curious whether the book builder works well for technical documentation or mainly narrative content.

Nice work. Good product

The highlighting feature was the first thing that caught my attention. Valuable insights from AI conversations often get buried in hundreds of messages, and being able to highlight key sections and revisit them later feels incredibly useful. For anyone using AI extensively for research, learning, or content creation, this can be a real productivity booster. The Book Builder is also a very compelling idea. Turning conversations into structured, shareable outputs has a lot of potential. One direction I’d love to see is expanding it with templates for different use cases, such as research reports, study notes, project documentation, or content drafts. Features like automatic chapter generation, multiple summary levels, collaborative editing, and integrations with platforms like Notion or Google Docs could make it even more powerful. I just discovered Foldi today, but it already feels like it’s addressing a real problem for heavy AI users. Looking forward to seeing how the product evolves and what new features the team brings next.

The book builder feature is genuinely clever — being able to compile months of AI conversations into an exportable document solves a real pain point. I use Claude daily for research and my history gets buried fast. One question: does Foldif support nested folder structures, or is it flat organization? Nested folders would be a game-changer for managing long-term projects across different topics.

good product and very helpful

This solves a real frustration — I've had dozens of useful AI conversations buried in scroll history with no way to find them again. The folder + highlight approach makes a lot of sense. The margin notes feature is particularly interesting; being able to annotate what was useful about a specific response rather than just saving the whole chat is a meaningful difference. Does it support export to markdown or PDF for offline reference?

good product and very helpful

Interesting, I get that you provide a service that spans multiple GPTs, but I'm not exactly sure what problem you solve. I say this only because I don't really find myself referencing old chats too often unless they were very recent. I may not be the typical user though.

hi everyone, solo dev here 👋 after ~20 years in software this is my first chrome extension — and i built it out of my own frustration. i run everything through chatgpt/claude/gemini, and a few months in i had hundreds of chats with genuinely good answers buried in them. i kept re-asking things i'd already solved. chat history is a feed; i wanted a library. so foldif adds folders, persistent highlights, margin notes and a "book builder" that compiles months of highlights into an exportable pdf/html book. it also auto-catches the TODOs hiding in AI responses before they vanish into scroll history. everything is local-first — your conversations never touch my servers. no api key, no signup wall, free core features. i'm here all day — happy to answer anything, and brutal feedback is genuinely welcome. that's how the product got this far.

Nice work. Good product

useful product. I'll check it out
