Tell Onsen your class, your textbook and your test date. Kapi, your capybara study buddy, builds the plan, quizzes you on the right chapters and tracks what you actually know.
For middle school, high school and college.
20 min today: mitosis phases
Built on what you already use
From "I have a test Friday" to walking in calm. No cramming, no guessing what to study.
Search by title or ISBN, or snap the contents page. Onsen maps every chapter so Kapi studies from what your teacher actually assigned.
Pick the chapters and the date. Kapi spreads short sessions across the week so you never cram the night before.
Quizzes, flashcards and explain-it-back sessions move each topic up five levels. You see what's solid and what's slipping.
Pick a date and how much it covers. This is the kind of plan Kapi builds for you.
4 sessions, ready the day before your test.
Example estimate. Your real plan adapts to how each quiz goes.
Every topic in your book moves up as you prove you know it. Not when you open the app, not when you read the answer.
Haven't touched it yet. Kapi's still waking up.
You've seen it. A few flashcards in.
You get most quiz questions right.
You can explain it back in your own words.
Still right days later. It's yours now.
Spaced review brings topics back right before you'd forget them.
Built around how memory works: spaced review, retrieval practice and a tutor that pushes you to think.
Kapi knows your classes, your chapters and the topics you keep missing. Ask anything, snap a worksheet, and get hints that lead you to the answer.
Every topic, colored by how well you know it.
Connect Canvas or Google Classroom. Due dates flow in, and Kapi spots quizzes and tests to plan around. Read-only, always.
Streaks and XP only come from real learning. Earn lanterns, steam and friends for Kapi's spring as your mastery grows.
Copying an answer feels fast until the test, when nothing's there. Onsen only rewards proof that you learned it.
Bite-sized sessions, friendly nudges and a buddy who celebrates the small wins.
Every class in one plan, synced with your assignments, so nothing sneaks up on you.
Load the course textbook, map the syllabus and spread the review across the weeks.
No. For graded work Kapi gives hints that lead you to the answer, one step at a time. You still do the thinking, which is the part that sticks on test day.
Search by title or ISBN, or snap a photo of the contents page. Onsen maps the chapters and topics so your quizzes and plan match what your class is actually covering.
It reads your classes and due dates so Kapi can plan around quizzes and tests. Access is read-only: Onsen never submits, edits or posts anything.
Middle school, high school and college students. Sessions are short for younger students and scale up to full course syllabi for college.
Onsen is coming to iPhone, iPad and the web. Early access opens this fall.
We're building Onsen because studying shouldn't mean copying answers you'll forget by Friday. Most study apps race to do the work for you. We wanted something better: a study buddy that plans around your real classes and textbook, gives you hints instead of answers, and is genuinely happy when you get it.
Kapi only rewards what you actually learned, so every streak and badge means something. That's the deal.
If that sounds like the study app you've been waiting for, early access opens this fall. We'll let you in as soon as Kapi's spring is warm.
