Foldif adds a knowledge layer on top of ChatGPT, Claude, and Gemini — so the good answers don't vanish into endless scroll.
Highlight any passage in an AI response (5 colors, Kindle-style), attach margin notes with your own thinking, auto-detect TODOs from answers and drop them into a kanban, and compile your highlights into a clean, shareable book with the Book Builder. Everything is searchable across every chat, and organized into nested folders.
Built for people who use AI daily for real work — developers, researchers, founders — and keep losing the answers they already paid attention to.
Privacy-first: your highlights and notes sync end-to-end encrypted with your own passphrase. No signup wall — install and use, with a 5-day Pro trial that activates automatically, no credit card.
