One honest answer: how should you ride today?

Sapere is a companion for cyclists. It reads your own intervals.icu data and turns it into one clear daily answer — with the reasoning shown, not hidden in a black box.

Your data, read — not hoarded

Sapere reads your activities, training load and planned workouts from your own intervals.icu account. intervals.icu stays the source of truth.

Reasoning you can see

Every readiness answer comes with the “why” — the signals behind it, in plain language, with honest uncertainty instead of false precision.
