Features
One place for what you have to do,
and what you want to remember.
Voice assistant
Say it, it's done.
Talk to t0 like you would to a person. It creates tasks, writes notes, books and moves calendar events, and remembers how you like things — no forms, no menus.
- Natural language, in real time
- Recurring tasks and reminders
- Remembers context across sessions
Notes & tasks
Notes that hold everything.
A block editor built for the messy middle of your day: drop in files and images, record audio and get a transcript, tag and prioritise, and lock anything sensitive.
- Attachments and audio with automatic transcripts
- Tags, priorities and quick filters
- Protected notes behind a passcode
Calendar
Your calendar, connected.
Connect Google Calendar and see your week next to your tasks. Add or reschedule by voice, or just drag things around — changes go straight back to Google.
- Two-way Google Calendar sync
- Week view beside your tasks
- Schedule and reschedule by voice
Everywhere
Web and iOS, always in sync.
The same workspace on the web and in the native iOS app. Capture on your phone, finish at your desk; changes appear instantly on every device.
- Realtime sync, no refresh needed
- Native iOS app with voice built in
- Light and dark themes that follow you
And more
Small things, done properly.
Recurring tasks
Daily, weekly, or “every other Tuesday” — set it once and it keeps coming back.
Priorities & tags
Colour-coded tags and priority levels so the list sorts itself.
Audio transcription
Record a thought inside a note and get the transcript alongside it.
Locked notes
Put a passcode on anything sensitive. Locked content stays hidden until you unlock it.
Memory
Tell the assistant something once — a name, a preference — and it remembers.
Weather & clock
Local weather and the time for your saved places, right on the dashboard.
