Knowledge Pills & Smart Reminders: Katav's AI Study Tools
Discover how Katav's new Knowledge Pills and Smart Exam Reminders use spaced repetition and active recall to help students retain information, ace exams, and eliminate last-minute cramming.

You took great notes in class. You even highlighted the important parts. Then two weeks later, the exam arrives — and most of it feels brand new.
That's not a discipline problem. It's the forgetting curve doing exactly what it always does: without review, we lose the majority of new information within days. The usual fix is a panicked all-nighter before the test, which is stressful, exhausting, and — research is clear on this — one of the least effective ways to actually learn.
This week, Katav shipped two new features built to break that cycle: Knowledge Pills and Smart Exam & Assignment Reminders. Both turn the notes you already take in Katav into an active study system that works in the background, so remembering what you learned stops being a last-minute scramble.
Meet Knowledge Pills: Spaced Repetition on Autopilot
A Knowledge Pill is a small, AI-generated dose of review delivered straight to your inbox — built automatically from your own class notes.
The idea is simple. The two study techniques with the strongest research backing are spaced repetition (reviewing material at increasing intervals) and active recall (forcing your brain to retrieve an answer instead of re-reading it). Both work brilliantly. Both are also annoying to schedule and maintain by hand. Knowledge Pills do the scheduling for you.
How Knowledge Pills Work
When you finish a class, you add it to your Knowledge Jar with a single tap. From there, Katav handles the rest:
The Recap (2 days later). A short, clear summary of the class lands in your inbox. It's a quick re-read at the exact moment your memory of the lecture is starting to fade — just enough to lock the key ideas back in.
The Recall (4 days later). A second email arrives, but this one doesn't hand you the answers. Instead, Katav's AI generates three active-recall questions drawn directly from your notes, with the answers tucked below in smaller text. You try to answer first, then check.
Every pill is generated from your notes — not a generic textbook — so the review always matches what your professor actually taught. Both emails are produced in your own language and delivered automatically. There's nothing to configure after that first tap.
Why Knowledge Pills Work
The timing isn't random. The Recap hits while the material is still fresh enough to consolidate, and the Recall arrives later — when retrieving the answer is genuinely a little hard. That small struggle is the point: effortful recall is what moves knowledge into long-term memory. Re-reading feels productive but barely moves the needle; being quizzed does.
In other words, Knowledge Pills give you the proven results of spaced repetition and flashcards without the work of building and maintaining a deck. Two emails, a few minutes each, and the lecture sticks.
Smart Exam & Assignment Reminders: Never Miss a Deadline
The second feature tackles the other half of the problem: deadlines you see coming but still aren't ready for.
A calendar alert tells you an exam exists. It doesn't help you prepare for it. Katav's Smart Reminders do both.
How Exam Reminders Work
When you mark a class as a test or exam and give it a date, Katav builds a personalized 7-day study series — one email per day for the week leading up to the exam.
Day 1 is orientation. It frames what's coming and how to approach the week.
Days 2 through 7 are focused deep-dives. Each email is AI-generated from the notes of the classes your exam actually covers, and includes recall questions, "watch out for this" tips, and memory hooks to make tricky concepts stick.
Crucially, the series is designed as one coherent plan, not seven disconnected emails. It paces your revision across the whole week so the material is genuinely spaced out — the opposite of cramming. You wake up each day already knowing what to study, and it's all drawn from your real coursework.
How Assignment Reminders Work
For assignments and projects, you don't need a full study plan — you need to not forget. So Katav keeps it lean: mark a class as a piece of work with a due date, and you'll get two reminders — one a week ahead, giving you real runway to start, and one on the due day itself, so nothing slips through.
Why This Beats a Standard Calendar Alert
A generic notification creates anxiety without offering a path forward. Katav's reminders replace that "I should be studying" dread with a concrete, manageable step for the day. Preparation becomes a series of small, scheduled actions instead of one overwhelming weekend — and that's what protects both your grades and your sleep.
Available on Katav Paid Plans
Knowledge Pills and Smart Exam & Assignment Reminders are premium features, available exclusively on Katav's paid plans.
Both rely on AI to read your notes and generate genuinely personalized study material — and that quality is what makes them worth opening. If you're on the free plan and you want your notes to keep working for you long after class ends, upgrading unlocks both features instantly. No new habits required: keep taking notes in Katav the way you already do, and let these tools turn them into lasting knowledge.
