Your diary, your notes, your personal knowledge base — and AI — all on your phone.
Innermost is a private AI diary and knowledge notebook. Write freely, keep
notes and build your personal knowledge base, and talk to your past self.
Everything runs on your device, so your words never leave your phone.
Write freely
A simple, beautiful diary with mood tracking, plus a notebook for ideas
and knowledge — your personal knowledge base grows as you write.
See your patterns
Insights surface the patterns behind your moods: what tends to trigger
stress, how your emotions change over the week, and gentle reminders of
how you coped before.
Chat with your past self
Ask questions and get answers grounded in your own history. "Three
months ago I felt the same way about work — how did I get through it?"
Innermost recalls relevant past entries, so every answer comes from
your own experience.
Ask your notes & knowledge base
Keep notes, ideas and things you learn, then ask questions about them —
answers come with sources, even offline.
