Backsight.app's answer
My parents are getting older, and somewhere along the way I became the one who keeps an eye on them — close enough to notice when something's a little off and say it out loud: you've mentioned
that twice now, you seem more tired lately. Then it hit me that nobody plays that role for me, or for my girlfriend. Nobody watches your own life closely enough, for long enough, to catch the
thing you can't see from the inside.
And everyone already keeps notes — a journal, voice memos, a line typed at 2am — we just never do anything with them, so the patterns stay invisible. Because you're bad at statistics about
yourself. You don't notice you've been low on 11 of the last 14 Sundays, or that your sleep tanks every week you skip the gym.
So Backsight turns your notes into honest stats — repetition, spikes, changes, correlations. Your notes become stats. Privately. Three bets make it different:
- A mirror, not a coach — it shows you what's in your data; it never diagnoses or tells you what to do. You draw the conclusion, the way I do for my parents.
- Private by default — on-device, end-to-end encrypted, accountless. I literally can't read your notes.
- Yours to keep — CSV import/export is always free, no lock-in. The optional subscription is just convenience: cross-device sync and a self-hosted MCP server to point your own AI agent at your
