Cognito vs Tassomai: A full comparison for GCSE and A-Level students

Cognito and Tassomai both help students prepare for exams, but they cover different parts of the picture. Cognito is a full study platform: animated video lessons, exam-board-mapped notes and built-in quizzes, flashcards and exam questions that help you retain what you've learned. Tassomai is an adaptive daily-quiz platform focused on building a short, repeatable revision habit with algorithmic gap-targeting, and it's aimed at GCSE (with a strong sciences pedigree).

Cognito is designed to be an all-in-one platform that supports you from learning the content, to remembering it, to knowing how to apply it in your exams. So when you sign up, you can add all of your subjects to your dashboard, ready to go, as you can see below.

Each subject is broken down into sections and subtopics, all mapped precisely to your specification. That means you only ever learn what you actually need to know for your paper, and you can see at a glance what's left to cover.

Each topic has a short video lesson and/or beautifully designed revision notes, and some have a little cheat sheet that summarises everything on one page. It's good for last-minute revision, or printing out and sticking on the wall.

Once you've learned a topic, you can build your own quiz mixing any set of topics you've covered. Cognito uses spaced repetition and interleaving to decide what to bring back and when, adapting to how you're doing. These are the two study techniques with the strongest evidence base in cognitive science.

And when you're ready for exam-style practice, you can work through real exam questions with typed answers. Then either self-mark against the mark scheme point by point, or use AI marking to check your answer against the examiner's points.

A feature-by-feature summary of how the two platforms compare.

Tassomai is an adaptive quiz-based platform built around short daily quizzes for KS3 and GCSE students, with a strong pedigree in GCSE sciences. Students answer a small batch of multiple-choice questions each day, and the algorithm decides which topics to bring back. It's paired with short explainer videos and an AI tutor called Mai that gives per-question hints. Free tier plus a paid subscription.

Strengths. The daily adaptive quiz habit with algorithmic gap-targeting is a genuine differentiator, and for students who stick with it, that short, repeatable format can be effective. Tassomai has a strong school-market presence in GCSE science with published outcome data.

Where it's less strong. Coverage stops at GCSE, so there's no A-Level, IB, IGCSE or AP. The format is quiz-first with limited video depth, which suits daily practice more than learning a topic from scratch. Home GCSE pricing (£44.99 / month) is on the higher end.

Honestly, the best move is to find what works for you, and it doesn't have to be all or nothing. Plenty of students layer daily quiz apps like Tassomai on top of a teaching platform.

What's great is that Cognito's videos and notes are free across every subject, with weekly caps on flashcards and exam questions. Tassomai has a 7-day free trial before the family subscription kicks in.

Broadly, Cognito will be a better fit if you want teaching, notes and exam practice in one place with a single low monthly price. Tassomai is worth a look if you want a strict daily quiz habit that nudges you every day and don't need standalone teaching content.
