Photo in, explanation out. Within a minute.
Point your camera at an exercise. Retrieva reads it, shows you what it saw, and explains it with the why included. Or it works out the whole sheet in one go.
Scan it. Get it. Ace it.
Take a photo of your homework, a worksheet or an old test. You get explanations that stick, and practice questions that come back until you know it.
- No payment details needed
- Stops on its own
- No ads
What you got wrong comes back. Until you know it.
You type your own answer first, and only then do you see the options. What you got wrong comes back sooner, what you already know comes back later. That way your time goes where it is needed.

How it works
From photo to explanation, in four steps.
Homework, a worksheet or an old test: point your camera at it. You can also upload Word, PowerPoint and PDF.
Take a photo
Straight from the app, with your camera. Several pages are fine, and you can pick a file too.
Check the recognised text
Retrieva first shows you what is on your sheet. Something not right? Then take a new photo.
Choose what you need
Everything worked out in one go, or an explanation per exercise with the why included. Don’t get a step? Then you ask a follow-up question.
Practise until you know it
It turns the same sheet into practice questions. What you got wrong comes back, what you already know only comes back later.

Why it works
Recognising is easy. Recalling is learning.
Three choices set it apart from an ordinary quiz app. All three are less comfortable than the alternative. That is exactly the point.
Yourself first, then the options
For every question you first type what you think. When you see the right answer, you think “yes, that one”. But in the test you have to come up with it yourself, and then it turns out not to be there. This is where you close that gap.
The confidence button
Before you see the answer, you say how sure you are. Sure and wrong is the dangerous box: that is not a gap in your knowledge but a misconception, and those questions get priority.
The review pile
You don’t have to schedule anything. Practise whenever it suits you: you get what you don’t know yet first, and what already went well moves to the back and comes round again later.
Ordinary quizzing
- You see the options straight away and recognise the answer
- Only right or wrong; how sure you were doesn’t count
- Everything comes back equally often, even what you already know
With Retrieva
- You recall the answer yourself first, just like in the test
- Misconceptions (sure and wrong) get priority
- Your time goes to what you don’t know yet
What’s inside
Everything for a subject in one place.
No separate apps for quizzing, planning and notes that know nothing about each other.

SummaryPracticeFlashcards
Progress that tracks itself
Every question you answer counts, even if you save nothing. Per subject and per topic you see where you get stuck, and with one button you get a summary, practice questions or flashcards built on your mistakes.
Timed test mode
Your dress rehearsal: the clock is running, no explanations in between, everything at the end. Type a topic and you quickly have a test, with different questions every time.
Flashcards, definition first
You get the explanation and have to name the term. That is harder than the other way round, and exactly what a test asks.
A planner that thinks ahead
Put your test in the calendar and Retrieva suggests study sessions in the days before: spread out, and heavier as the test gets closer.
Notes that do something
Write in Markdown. Done? One button and your note becomes a set of practice questions or flashcards.
A study timer that counts honestly
Only the time you actually let run counts. Per subject and per week you see how much time went into it.
Import an old test
Put in a photo or PDF of an old test. Retrieva pulls out the questions and makes a new one on the same material. Same difficulty, easier or one level up.
Everything together in your library
Worked solutions, tests, flashcards, summaries and notes are grouped per subject, newest first. Nothing gets lost in a chat history.

What we deliberately left out
No points, badges or streaks. They work for two weeks, and after that you stop as soon as the streak breaks. There is also no chat window for asking just anything: you ask about the exercise in front of you. And you mark your open questions yourself, because comparing honestly teaches you more than a model that approves everything.
Five levels
Not just whether you know it, but whether you can use it.
Every question sits at one of five levels, from bare facts to a reasoned judgement. You see the scale everywhere as five small bars, and your progress shows where you get stuck: on remembering, or on applying.
KnowingRecognising facts and concepts
UnderstandingExplaining in your own words

How it works: click a plan, create an account, pay with iDEAL or card. The first 7 days are always free; if you pay right away, your subscription only starts after that.
Class or school
One licence per pupil and one invoice for the school. For schools we are happy to prepare a tailored quote.
All amounts are in euros and include VAT. You pay with iDEAL or card. A monthly subscription renews automatically; you get an email three days before, and you can always cancel for free in the app. A yearly subscription is paid in one go and does not renew automatically: you get an email before it ends, and then you decide whether to renew. Every payment comes with an invoice by email.
Questions
What you want to know before you start.
Question not listed? Email us and we will reply within 2 working days.
Who is Retrieva for?
For anyone who has to know something by a date that is already set. From the first year of secondary school to university, and just as much your driving theory, a professional exam or a course alongside your job. You create your own subjects, so the app imposes no curriculum and no age on you.
Does Retrieva do my homework for me?
It can, but that is not what it is built for. You can have the whole sheet worked out in one go when you are stuck and it has to be finished. If you go exercise by exercise, Retrieva explains the steps along with the why, only gives the final answer once the way there is clear, and finishes with a check question.
Which files can I upload?
Photos (straight from the app, with your camera), PDF, Word (.docx), PowerPoint (.pptx) and text files. Up to six files at once, so several pages of a worksheet are no problem.
Do I need my own AI key or a ChatGPT subscription?
No. AI usage is included in your subscription. You create an account and it works. There is a generous fair-use limit that normal studying never comes near; if you do reach it (more than 120 AI actions in a day), only the AI pauses until the next day. Practising with what you already have keeps working.
Is everything the AI makes correct?
No, and we say so honestly. That is why Retrieva first shows what it read from a photo, and every set of questions goes to a review screen before you practise. Where the model is unsure, it tries to say so. Always check important answers against your course material.
A question without an explanation is rejected, even if the model produces it. An answer you can see but don’t understand teaches you nothing.
How do cancelling and renewing work?
A monthly subscription renews automatically, and you cancel whenever you like: with one click in the app, free of charge. You get an email three days before each renewal. After cancelling you keep access until the end of the month you have paid for.
A yearly subscription is paid in one go for the whole year; stopping partway with a refund is not possible. It also does not renew automatically, so there is nothing to cancel. A month, a week and a day before it ends you get an email, and then you decide whether to renew.
As a consumer you also have a 14-day right of withdrawal; see the terms of service.
What happens to my work if I stop?
Before you stop you can export everything: subjects, questions, tests, progress, planning and notes, as Word, PDF, CSV, Markdown, JSON or ICS. If your subscription ends, your data is kept so you can come back. If you do not use Retrieva for 24 months, we delete your account; you get an email about it a month beforehand. You can always delete it sooner yourself.
I’m under 16. Can I have an account?
Yes, with permission from a parent or guardian. That is what privacy law requires. When you sign up we ask you to confirm that you are 16 or older, or that a parent or guardian gives permission; that parent or guardian is then responsible for it. On the Family plan the parent is the one who pays and manages the accounts.
What happens to my data?
Your subjects, questions and progress are in your own protected account. We sell nothing on, show no ads and do not use your material to train models.
To create questions, we send the text you enter to the AI model Retrieva works with. The privacy statement sets out exactly which company that is, where it happens and how long what is kept.
Does it work on my phone?
Yes. Retrieva runs in the browser and adapts to your screen. There is nothing to install. You use the camera straight away to photograph an exercise or an old test. Everything is stored on the server, so you start on your laptop and carry on on the train.
Can our school or class get a licence?
Yes. Per pupil, with one invoice for the school. For schools we are happy to prepare a tailored quote: email us with the number of pupils and the subjects.
