Medicine, law, maths, psychology, economics: if it's in your course, Rosko quizzes you on it.

You've reread everything. On exam day, your mind goes blank.

Rereading makes you feel like you know it. Testing yourself shows what you've really retained, and that's also what makes it stick.

Of ten study methods put to the test, only two stand out as highly useful: testing yourself and spacing it out.

Three steps to start revising

01

Upload your course

Rosko reads the whole document and extracts concepts one by one, showing where each comes from.

02

Rosko asks you questions

Open questions or multiple choice, Rosko corrects you right away, with course citations.

03

A plan based on your exam date

Revision intervals shorten as the exam approaches.

Your course, not the internet

Every correction points back to your course.

Rosko starts from your professor's material and cites the passage so you can check it. If an excerpt can't be found word for word in the document, it warns you.

Your questions

Do my courses stay private?

Your courses, notes and answers remain yours. We don't use them to train AI models and we don't sell them. The text needed goes through our AI providers, who are not allowed to use it to train their models. Privacy

What if Rosko gets it wrong?

It can happen, as with any AI. That's why it cites your course: you can check the passage. If in doubt, your material and your professor are right.

Does it work for maths and physics?

Yes. In Flash, Rosko offers practice exercises and corrects them step by step.

Which files can I upload?

PDF, PowerPoint, Word, Markdown and text, or photos of your notebook. A scan or a photo works too: Rosko transcribes it first, which uses a few more credits.

Is there really no commitment?

Yes. Discovery doesn't require a bank card, and you can stop a subscription whenever you want from your account.
