You spend more time filing notes than writing them
Every new note means picking a folder, a tag, a tool. You stop to organize before you've finished the thought — and the idea you wanted to capture is already gone.
Notes that organize themselves — and remember everything you've written before.

Your notes are yours. We don't train on them.
How it works
Otto reads each note, files it in the right folder, pulls out your to-dos, and connects it to related notes and topics you've written before.
The problem
The moments every note-taker eventually runs into.
Every new note means picking a folder, a tag, a tool. You stop to organize before you've finished the thought — and the idea you wanted to capture is already gone.
Lecture notes, voice memos, PDFs, whiteboard photos — every kind of capture lives in a different app. When you need it back, you can't remember where you saved it.
Most apps pick a side — text editor or canvas. The ones that do both keep typing and drawing in separate boxes you size and place yourself. No app lets you write, sketch, and annotate freely without managing the layout.
What Otto does
Voice memos, multi-device sync, auto-filing, tasks, connections, instant recall — six jobs Otto does automatically.
Why Otto
Each one gets a piece. Otto puts the pieces together.
