Foldif

Your best AI answers are buried in hundreds of chats.

Foldif turns ChatGPT, Claude, and Gemini from a feed you scroll into a library you own: one extension, one system, across all three.

Momentum: Fazier Product of the Day, Product of the Week, and Product of the Month. Product Hunt Top 3%, #28 of 900+ launches.

CAPTURE WHAT MATTERS

This is the part that actually saves you time. Highlight any AI response in 5 colors. It survives reloads, forever, so you stop re-copying answers into a doc you'll forget exists. Attach a private margin note to any highlight, the way you'd scribble in the margin of a real book. Found an explanation worth remembering? Turn it into a spaced-repetition flashcard (SM-2) with one click, so it actually resurfaces later instead of dying in your history.

ORGANIZE

Unlimited nested, color-coded folders, the same tree across ChatGPT, Claude, and Gemini. Pin the messages that matter to a sticky bar so you're not scrolling to find them again. Add a note to an entire conversation, with an optional expiry if it's only relevant for a week. Full-text search across every conversation, note, and prompt you've ever had.

TURN CHATS INTO KNOWLEDGE

Months of highlights, compiled into an actual book, not a folder of screenshots. Book Builder gives you 11 block types, 5 cover themes, drag and drop chapters, and auto-save, exportable as PDF or HTML. Working from research chats? Pull citations (DOI, arXiv, ISBN) and export straight to BibTeX.

NEVER LOSE A TODO

Foldif reads AI responses in 13 languages and auto-detects action items, decisions, and open questions, then drops them onto a kanban board with due dates and priority before they vanish into scroll history you'll never revisit.

WORK ACROSS AIs

Hand a conversation off from ChatGPT to Claude or Gemini with full context attached. Re-ask the same question on a different AI in one click. Fork a chat at any message and see every branch you've taken. Keep work and personal separate with 9 isolated profile workspaces.

PRIVACY-FIRST

Everything lives in your browser: local-first storage, zero conversation tracking. Smart redaction masks emails, phone numbers, and card numbers before they ever reach the AI. Privacy blur (Alt+Shift+B) for cafés and screen shares. Want sync across devices? Optional end-to-end encryption (AES-256-GCM).

No API key. No signup wall to try it. Free to start, built by a solo developer who got tired of re-asking questions he'd already solved somewhere in his own chat history.
