Tassomai vs Cognito: a daily practice routine or a revision library

Tassomai is a daily practice programme used by more than 300,000 students in over 500 schools, and ranked fifth in TIME's World's Top EdTech Companies of 2026. Every pupil gets a Daily Goal in each subject, chosen by an algorithm from their own answers, so practice keeps returning to the topics they are weakest on and the ones they are starting to forget. Teachers and parents see the results.

Schools and parents often compare Tassomai with Cognito, a revision library of notes, video lessons, quizzes, flashcards and exam questions. On Cognito, pupils choose a topic and work through the material.

The difference is who decides what a pupil practises each day. This comparison covers how pupils practise, what happens when they get stuck, what teachers and parents see, the evidence behind Tassomai, subjects and what each costs families.

• Tassomai decides what each pupil practises every day, so they don't have to work out what to revise. On Cognito, pupils choose for themselves.

• Tassomai mixes spaced, interleaved quizzes from across the whole course, so earlier topics keep coming back. Cognito uses spaced repetition in its flashcards.

• When a pupil gets stuck, Tassomai's AI tutor Mai gives step-by-step guidance mapped to UK mark schemes.

• Teachers get the Understanding Grid, the Tree and Group Quiz, and parents get a progress email every Monday.

• In Tassomai's study of over 68,000 exam results, 90% of strong users achieved a strong pass or better, against 68% nationally.

With Tassomai, each pupil gets a Daily Goal in each subject, about 10 to 15 minutes of short quizzes. The algorithm picks the questions from their past answers, including how accurate and how quick they were, so weak topics come up more often and earlier topics come back before they are forgotten. Questions from across the course are mixed together.

This is the retrieval practice and interleaving that cognitive science research supports, and it happens for every pupil every day.

On Cognito, pupils pick a course and a topic, then choose how to revise it: revision notes, a video lesson, a quiz, flashcards, exam-style questions or past papers. They can also build their own quizzes across several topics, and Cognito's flashcards use spaced repetition.

That suits a pupil who already knows what they need to revise. Most don't. Left to choose, many pupils go back to topics they already feel confident about, and topics learned in Year 10 fade by the summer of Year 11.

When a pupil gets a question wrong on Tassomai, Mai, Tassomai's AI tutor, gives step-by-step guidance mapped to UK mark schemes. The topic then comes back in later quizzes, so a mistake turns into extra practice on exactly that point.

On Cognito, a pupil who is stuck can watch the video lesson or read the revision notes for the topic, and gets AI feedback on exam-style questions.

Tassomai is built for the classroom. Daily Goals are set automatically, so teachers don't have to set revision homework every week, and they can see who is keeping up:

• The Understanding Grid shows every pupil's accuracy on every topic, colour-coded, so a teacher can see a class's gaps at a glance.

• The Tree shows how much of the course each pupil has covered.

• Group Quiz turns the class's own data into a ready-made starter on the board, using the questions the class finds hardest.

• Leaders can see usage and Daily Goal completion by class and year group.

One partner school, St John Bosco College, estimated that Tassomai saved each GCSE teacher 2 hours per week per class.

Parents get a dashboard and a progress email every Monday showing the days their child was active, how many questions they answered, their accuracy and their strongest and weakest topics of the week.

Cognito sells school-wide licences that give pupils and teachers Pro access, and its schools page lists a teacher dashboard and progress tracking. Its public pages do not describe reports for parents.

Tassomai publishes the results of its own data studies on its impact page:

• A 2017 study took in over 68,000 exam module results from schools using Tassomai. 90% of strong users achieved a strong pass or better, against 68% nationally, and 50% achieved a top grade.

• A 2018/19 trial followed a randomised sample of 1,500 students. Students of all abilities improved their knowledge recall, the improvement grew with use, and the effect was more marked for students who started with lower attainment.

The more a student uses Tassomai, the better their results, which is why the Daily Goal matters: it makes regular use the default for every pupil.

Tassomai concentrates on the years up to GCSE exams. It covers KS2 maths, English and science, then KS3 and GCSE science, maths, English language and literature, history, geography, computer science and languages. Questions are matched to each pupil's exam board.

Cognito covers KS3, GCSE, A-Level, IB and AP, across 15 subjects and 10 UK and international exam boards.

Tassomai families pay monthly by year group, and every plan starts with a 7-day free trial:

• Years 3 to 6: £8.99 a month

• Years 7 and 8: £29.99 a month

• Years 9 to 11: £44.99 a month

Cognito's revision notes, videos, quizzes and flashcards are free to use, with weekly limits. Cognito Pro removes the limits and covers all subjects for £9.99 a month, or £72 a year billed annually, with a 14-day money-back guarantee.

For GCSE years, Tassomai costs more than Cognito Pro because it does more than open up a library. It plans each pupil's practice every day, brings back what they are forgetting, gives step-by-step help from Mai and sends parents a progress report every week.

A library is useful when a pupil knows exactly what to look up. The harder problem for most pupils is doing a little practice every day, on the right topics, for two years. Tassomai is built for exactly that: it decides what to practise, brings back what is being forgotten, helps when a pupil is stuck and shows teachers and parents whether it is happening.

If your school wants a daily retrieval habit that runs without teachers setting tasks, or you want to know your child is revising the right things, Tassomai is designed for you.
