Stop losing what AI teaches you.
Highlight any AI response. Add margin notes. Compile into a beautiful book.
From AI conversations to your own knowledge base.
Highlight what matters, jot a margin note, and compile it all into beautiful exportable books — plus the organization tools every AI should have shipped with.
Highlights
Select any text in a ChatGPT, Claude, or Gemini response and color-highlight it. Highlights persist across page reloads and become the raw material for your books and notes.
Margin Notes
Hover any highlight, click the pencil, and write a private note next to it. Like writing in the margin of a book — but on AI conversations.
Book Builder
Turn your highlights into a real, exportable book. 11 block types, 5 cover themes, drag-drop chapters, auto-save, and PDF/HTML export.
TODO System
Foldif reads AI responses in 13 languages and detects action items, decisions, and questions automatically. Quick-add from any selection. Kanban board for triage.
Folders & Projects
Create folders and sub-folders for every AI you use. If you use more than one, the same tree appears everywhere.
Multi-Profile
Separate work and personal AI lives. Nine color-coded profiles, each with their own folders, prompts, and history. Switch instantly.
Context Handoff
Switch AIs mid-conversation with full history. Never start over when changing models.
Cloud Sync
Keep your highlights, notes, and library in sync across devices. End-to-end encrypted (AES-256-GCM), Pro-only, always opt-in.
Share & Export Hub
Export any conversation as Markdown, PNG, PDF, or public link. One click to WhatsApp, Email, Telegram, X, LinkedIn, or Reddit.
Power Actions
Expand, shorten, simplify — or run your own custom prompt — on any AI response in one click. Build a personal action library.
Fork & Branch Tree
Split a conversation at any message and continue in a different AI. See every fork in a visual tree with searchable timeline.
Flashcards
Turn any AI explanation into a spaced-repetition flashcard with one click. SM-2 algorithm, due queue, sourced back to the original conversation.
Highlight. Note.
Book.
AI conversations are full of insight — and impossible to come back to. Foldif gives you the three primitives you need to keep them: highlight what matters, jot a margin note, then assemble it into a real, exportable book.
The three core primitives of knowledge work are: capture, annotate, and synthesize. Each step adds context the next can't recover.
Your AI just
