That's not a you problem — it's a tools problem.

Questions we get a lot.
How is this different from Quizlet or Anki?
Quizlet relies on user-uploaded decks with lots of errors. Anki is powerful but has a brutal UX. Cortest combines AI generation, modern UX, and spaced repetition in one place — with Focus Lock built in.
Is the AI accurate?
Every card passes schema validation before it ships, and each one can link back to its source passage. If you spot an error, report it in-app and we'll improve.
What happens to my data?
Your content is yours. We never train on uploaded material without explicit opt-in. Full export and deletion are one click away in settings.
Does Focus Lock actually block apps?
On web, we use the Fullscreen + Visibility APIs to track distraction. On mobile, we integrate with iOS Screen Time and Android Digital Wellbeing for hard blocking.
Can I import from Anki?
Yes — we support .apkg import with full review-history preservation.
Can I cancel anytime?
Two clicks, no dark patterns, no "are you sure you want to leave??" modals.
