Not more hours.
Just the right ones.
Most students spend hours re-reading notes they'll forget by tomorrow. There's a method that actually works — it's been sitting in research papers for decades. We built a platform around it.

of what's studied is forgotten within 24 hours
Re-reading notes feels like learning. Mostly, it isn't. This has been measured and re-measured for over a century.

study techniques earned a “High utility” rating
Ten popular study methods, reviewed across every age group and subject. Practice testing was the only one that held up. The rest — highlighting, re-reading, summarising — rated low or moderate.

61% vs 40%
recalled a week later — tested vs. just re-studied
Same material, same students. One group took a practice test on it, the other re-read it. A week later, the tested group remembered far more. That gap is the entire idea behind Crisp.

Built for everyone around the student
To parents.
You already pay for tuition, apps, workbooks. We're not asking you to add one more thing — we're asking you to put that time and money behind something that's actually been shown to work.
To teachers.
You already know which students are falling behind. Crisp just shows you three weeks earlier — with the exact chapter and the exact question they got wrong.
To schools.
This isn't ed-tech theatre with leaderboards and confetti. It's a practice-testing engine, priced so budget is never the reason to say no.
Every student deserves a study method that's been proven — not just marketed.
We can't do that alone. It takes a parent who checks in, a teacher who assigns the right test, a school that makes room for it. Crisp is the platform. You're the reason it works.
We're not asking you to trust an app. We're asking you to trust research that's held up for decades — and give your student a real shot at using it.
