Our promises

Sapere exists so you leave smarter than you came. These five promises hold no matter how much money breaking them would make.

Sapere never invents a source. If it cannot find one, it tells you.
Your memory is yours. What you keep is never sold, shared, read or trained on.
No ads, ever. Nobody can pay to appear in an answer.
Sapere never pretends to be sure. When experts disagree or nobody knows, it says so.
No pornography. Safe search is always on. There is no switch.

Sapere is Latin for “to know”. Sapere aude: dare to know.

You’re Pro.

Thank you. Ask without limits.

When will you check?

Tie it to something you already do every day. People who plan “after X, I’ll do my check” keep the habit far better than people who just set an alarm.

After…

Around

Evening is best: sleep helps file what you just recalled. Sapere never reminds you during school hours (07:00–15:00) or after 21:00.

Last step: put it in your calendar, so your phone reminds you even when Sapere is closed.

Your exam

Sapere spaces your checks so what you kept is strongest on the day, with one extra check on the latest day that still carries it there.

Deep Answer

A careful researcher’s work in about 2–3 minutes. Sapere splits your question into smaller ones, reads about a dozen web pages, follows claims back to their original source, argues against itself, and checks every sentence before you see it.
