Why does the electron transport chain stop without oxygen?
Study less. Remember more.
Flashcards that come back right before you would forget them, AI quizzes built from the material you upload, and decks you share with your group.
Features
Everything you need to keep it in your head.
Write or import your cards, review them at the right moment and let AI turn the slides you upload into practice questions. One place for the whole semester.
How it works
Review less. Remember longer.
Rekuro shows each card again shortly before you would forget it. The better you know a card, the longer it stays away, so your daily session stays short while your memory gets stronger.
Six phases
New cards start in phase 1. Every time you know a card, it moves up a phase and the gap until you see it again gets longer, from less than a day up to several months. Cards you know well rarely come back, so you spend your time on the ones that still need practice.
- Phase 1under 1 day
- Phase 21–3 days
- Phase 33–7 days
- Phase 47–21 days
- Phase 521–60 days
- Phase 6over 60 days
Four answers
When you reveal the answer, you rate how well you knew the card. You have four options: Wrong, Hard, Good and Easy.
AI quizzing
Your slides, turned into a study partner.
Upload a lecture as a PDF, or add your own texts and notes, and get questions in your own words, graded with feedback. Every answer points back to the slide or passage it came from, so you can always check.
Quiz me on this lecture
The AI asks open questions, not multiple choice. You answer freely and get a grade, what was missing and a full answer.
- Free-text answers, graded with feedback
- A full answer after every question
- Slides stay private to your group
Oxygen is the final electron acceptor. Without it, electrons back up and the chain stops.
Better cards, checked by AI
Card check reads your deck and flags cards that are wrong, unclear or try to cover too much. You choose which suggestions to apply.
- Checks correctness, clarity and size
- Splits overloaded cards into focused ones
- Nothing changes without your OK

AI Lecturer
Your lecturer, on call before every exam.
Pick the lectures you want to practise and start a chat. The AI Lecturer asks the questions, checks your answers and shows you where everything is in the slides.
You: How can you help me?
AI Lecturer: I work only with the lecture content you upload or that I’ve been trained with, and I help you get it into your head:
- Quiz you with open questions on whole lectures or single lessons.
- Check your answers in your own words and show what a full answer contains.
I can quiz you on any lecture you have uploaded, for example:
- Financial Accounting
- Business Psychology
- Business Mathematics
- Chinese
- German

Study together, keep it private. Create private study groups where you can share your cards and lectures. Whole semesters or classes can study with cards that only need to be created once, and everyone gets them.

FAQ
-
Rekuro is a flashcard app built for students. You create or import cards, review them with spaced repetition, and let AI quiz you on your lecture slides, so you spend your study time on what you are about to forget.
-
Rekuro schedules your reviews with FSRS, a modern scheduling algorithm. After each card you rate how well you knew it, and Rekuro brings it back shortly before you would forget it. Easy cards come back less often, hard ones more often.
-
Each card sits in one of six phases that show how well you know it. Good or Easy moves the card up one phase, Hard keeps it where it is, and Wrong moves it down exactly one. The higher the phase, the longer the gap until the next review: under a day in phase 1, more than 60 days in phase 6.
-
Yes. You can import cards from a CSV file or from an Anki export. Your cards land in a new deck that you can edit, reorganise and share like any other.
-
Yes. Every card stores both directions, for example word to translation and translation to word. Turn on “Ask in both directions” for a lecture and Rekuro picks the direction at random each time a card comes up. The card keeps one shared progress either way.
-
Upload your slides as a PDF and the AI asks you questions about them. You answer in your own words, it grades your answer, explains what was missing and shows you a full answer. Rekuro does not provide any lecture slides: the AI only works with the content you upload.
-
It reviews your cards for correctness, clarity and size, and suggests improvements, for example splitting a card that asks too much at once. You decide which suggestions to keep.
-
Only you, unless you share a deck with your group. Uploaded slides stay private to the group that uploaded them. Your account and study data are stored in the EU; for AI features, only the text needed is sent to our AI provider in the USA.
-
A mobile app is planned. Until then, Rekuro works in your phone's browser, and review sessions are designed to be comfortable on a small screen.
