SILONotesYour notes. Your way
A private notebook for your phone and computer, with AI only when you decide.
Built for people who care who sees their notes
Many notes apps want an account and keep your notes on their servers. SILONotes keeps them on your device, and AI only helps when you ask.
Private from the first note
Your notes stay on your device, and you never make an account. They leave it only when you choose to send them, and we do not track what you do.
Locked where it counts
Pair your phone and computer with six words. They sync through a folder you choose, in archives only your two devices can open. Add a password to lock your backups too.
Easy to pick up
Write, tick off tasks, record a voice note or listen to a book, with or without internet. Pick one of six themes, and it looks and feels the same on your phone and your computer.
AI that shows its work
AI Magic summarizes or polishes a note with one button. Use a provider you trust, run AI on your own computer, or leave it off.
