Second Brain is a calm place for everything on your mind. Capture it in seconds by voice or text, check what Smart fill made of it, and ask your notes when you need it back, with sources you can open and check.
Just say it.
Voice capture starts listening the moment it opens, in eight languages. Every task, plan and idea is caught as you speak, and the original is kept.
One sentence. Three things done.
Smart fill turns what you said into tasks, events and notes with dates and times filled in. You check every field before anything is created.
Ask anything.
Answers come only from what you saved, with the sources listed so you can open and check them.
Your day, and your week.
What's due and what's next on one calm screen, with your Apple Calendar beside your tasks, reminders and an optional morning summary.
Nothing is lost.
Your original words stay next to everything made from them. Any organizing can be undone, and you can export your whole library at any time.
Private by default.
On-device AI first and no ads in the app. Cloud sync and cloud AI each wait for your yes, and any capture can stay on this iPhone only. How that works.
