Your flashcards. Finally in rhythm.
merkbar pulls your handwritten cards out of GoodNotes and makes sure exactly the right ones come back until they really stick. Classic, multiple choice, or as an AI exam.
Ready in minutes. No credit card required.
From handwriting to knowledge that sticks
Three steps, then your studying runs on its own at the right pace.
Import from GoodNotes
Upload your GoodNotes file or a PDF. merkbar detects the question and answer on each card and turns them into your deck.
Pick a mode
Practice classic with flip, quiz yourself with multiple choice, or face the AI exam with a free answer and honest feedback.
Stay in the Leitner rhythm
Every card moves through five boxes. What sticks comes back less often. What wobbles comes back more. You see exactly what is due each day.
The right mode for every mind
Switch any time. Same cards, three ways to test yourself.
Classic
Read the card, flip it, rate yourself honestly. Four levels from Again to Easy decide when the card returns.
Multiple choice
Four answers, one is right. Quick quizzing for in between, with instant reveal and explanation.
AI exam
Answer freely in your own words. An AI grades like an oral exam, gives you a score and tells you what is still missing. You set the strictness yourself.
Everything to make knowledge stay
GoodNotes import
Handwritten cards are detected automatically and split into question and answer. You review everything in a preview before the deck is created.
Spaced repetition with Leitner
The proven five-box system schedules every review at the best moment. You study less and remember more.
Honest AI grading
The AI exam takes your free answer seriously, recognizes key terms and gives you concrete feedback in a friendly tone.
Progress at a glance
Streak, learning history, success rate per deck and your Leitner boxes. You see clearly how much already sticks.
Staying on track made easy
Daily goals and a growing streak keep you in rhythm, without pressure and without a wagging finger.
With you everywhere
merkbar runs on phone and desktop, installs as an app and is always there when you have a free minute.
Good to know
How do my cards get from GoodNotes into the app?
You export your notes as a GoodNotes file or PDF and upload it. merkbar reads the pages, detects question and answer and shows you all cards in a preview before the deck is created.
What exactly is the AI exam?
You answer a question freely in your own words. An AI grades your answer like a fair examiner in an oral exam, gives a score from 0 to 100 and explains what was good and what is missing. You set the strictness yourself: lenient, balanced or strict.
What is the Leitner system?
A spaced repetition method with five boxes. Cards you know well move to the back and return less often. Cards that still wobble stay up front and return more often. So you review at exactly the right time.
Does merkbar cost anything?
You can start for free and use the core features. Additional offerings are planned for later. The focus stays the same: a tool that actually helps you learn.
Does it work on my phone?
Yes. merkbar is built for phone and desktop and can be added to your home screen as an app. So you study on the train just as comfortably as at your desk.
