# Insights

> What Cymo infers from the three core signals over time.

## Signals become insights

Signals describe a moment. Insights describe a pattern: a night of sleep, a stressful afternoon, a week of slower walking. Cymatics computes them on the server, so you get the result without processing raw readings yourself.

## Analyses, windows and revisions

Insights arrive as analyses: each has a `kind`, the `track_id` and, once identity is established, the `person_id` it describes, a time window and the model that produced it. Sleep is split into sessions automatically, and a score appears once the session ends. When late data improves an analysis, it keeps its ID and its `revision` goes up.

## Insights and plans

Each insight is a capability your plan can include. Operations that serve one, such as vitals, stress and sleep, need a plan that includes it, or the API answers `403 feature_not_entitled`. Other operations only need the right scope. The simulator has test data for every capability.
