About

Observer

Features
Read full description

A self-reflection tool for hard weeks. You write about a recent period work, family, what's been on your mind, what hasn't. Don't clean it up. The point is to let it come out the way it actually does, not the way you'd report it to someone. Observer reads what you wrote and returns observations flat, factual, no reassurance. Calibrated for the things autistic and neurodivergent people often miss in themselves: where presentation has gotten more polished under load (a stress signal, not a wellness signal), what's carrying disproportionate cognitive weight, what's conspicuously not in the account at all. It's not a diagnostic tool, a therapy app, or a coach. It doesn't track moods, suggest interventions, or store anything on a server. It's a writing tool that surfaces patterns in your own words for you to interpret. It was built after a hard week. A sick dog needing emergency surgery, family worry, a hard week at work. When reflecting clearly on what was actually loading me up was harder than it should have been. The first thing the app surfaced was something I hadn't connected: a complicated piece of work running quietly in the background was contributing more than I'd given it credit for.
