Your thoughts are yours.
We just help you organize them.
Outlines, todos, mind maps, journals — one tool that adapts to how you think. End-to-end encrypted so not even we can read your notes. Start free.
One tool to think it through
Listetto gives you a space to dump everything in your head, then shape it into something useful. Here's what makes it click.
Depth Without Limits
Nest lists as deep as your thinking goes. Break big ideas into smaller pieces, then break those down further — until everything clicks.
Offline-First
Everything lives on your device first. Work without internet, and changes sync automatically when you reconnect. Your data is always with you.
Instant Search
Find anything in milliseconds. Full-text search across every list, note, and nested item — no matter how deep it lives.
Built-In Sharing
Share individual branches or entire trees with your team. Collaborate in real-time with fine-grained permissions.
Private by Design
End-to-end encryption by default. Zero-knowledge architecture means nobody — not even us — can read your data.
Every Platform
Native apps for iOS, Android, macOS, Windows, and Linux. Plus a fast web app. Real-time sync keeps everything in lockstep.
Great outliners help you think.
We just add a layer of privacy.
Start free with full encryption on one device. Upgrade when you need sync.
