One extension. Three AIs. Endless possibilities.
Foldif connects ChatGPT, Claude, and Gemini — letting them work together, not just side by side. Below is every feature, explained.
Features no other extension has.
These features require orchestrating multiple AI platforms simultaneously. No other tool does any of them.

- ✓5 colors — yellow, blue, red, green, purple
- ✓Press H to highlight your selection instantly
- ✓Persistent across page reloads and DOM rerenders
- ✓Feeds into Margin Notes and Book Builder
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.
- ✓Per-highlight private annotations
- ✓500 character notes, Ctrl+Enter to save

Your AI conversations are yours.
We built Foldif with a simple rule: we never touch your conversations.
Local-First Storage
All your data — folders, prompts, pins, notes — lives on your device. Nothing is uploaded without your explicit action. Fast, private, works offline. Pro users can enable optional E2E-encrypted cloud sync for cross-device access.
Zero Conversation Tracking
We never read, log, analyze, or sell your AI conversations. Foldif is a UI layer — your chats stay between you and the AI.
No API Key Required
Foldif works with your existing ChatGPT, Claude, and Gemini accounts. No new credentials, no billing, no API limits.
Auto Dark / Light Mode
Foldif matches each platform's theme automatically — dark when ChatGPT is dark, light when Claude is light.
Encrypted Cloud Sync
Pro users can opt in to cross-device sync. All synced data is end-to-end encrypted (AES-256-GCM) before it leaves your device — the server only ever sees ciphertext. Full chat content and API keys are never uploaded.
All of this. One extension.
