μάθησις — the act of learning
Mathesis is a free learning platform. It turns real course material into a living curriculum — lessons where you see the data you are talking about, interactive labs, timed exercises and a concept map that follows your mastery — so the next step is always the right one.
Free education, and training worthy of the hardest exams
Knowledge has always been humanity's shared inheritance. Whoever you are, wherever you live and whatever you can afford, you should be able to learn — and to prepare seriously for the exams, competitive entrance exams and certifications that open doors.
Understand, practise, prove it
See the data
Lessons show the tables you are working with — every row, every column explained — before and after each query.
Run and experiment
Every example runs live. Change it, break it, run it again: each run works on your own private copy.
Practise in labs
Write the query yourself. It is graded against the reference result, with hints when you are stuck.
Prove your mastery
Timed evaluations unlock the next concepts on your map. Train as often as you like; pass when you are ready.
AI should open doors, not close them
Mathesis was designed and built together with Claude, an AI model made by Anthropic — the platform, the SQL engine that runs every exercise, and the course itself.
We think this is what artificial intelligence is for: not replacing people, but giving everyone a patient, rigorous place to learn. A tool that helps one more student understand a concept, pass an exam or change careers is a tool doing its job.
Learning is how humanity moves forward. Mathesis exists to help more people do it.
One platform, every subject
Each subject is its own space, with its own courses. Computer science is open today; mathematics, physics and chemistry are being written to the same standard — real material, live practice, exam-grade evaluations. Every course is complete and free.
Databases, programming and algorithms: the languages of the digital world, learned by running real code.
From arithmetic to algebra, analysis and probability — foundations for everyone, rigour for competitive entrance exams.
Mechanics, electricity, waves and thermodynamics, with worked problems at exam level.
Atoms, reactions, equilibria and organic chemistry, explained step by step.
