The tutor that learns how you learn.
Drop in your lectures, readings and recordings. Coursity turns them into a living course — one that re-teaches, re-plans and re-schedules itself around you.
One tutor. The whole loop.
From raw materials to scheduled mastery — every step watches how you learn, and adjusts.
Ask like a person.
Get taught like one.
Every answer is grounded in your materials — cited to the lecture minute or textbook page — and ends with the question that moves you forward.
- Cited answers — jump straight to the source moment.
- Socratic by default — it asks back until the idea holds.
Same concept.
Your format.
Coursity notices what lands — and rewrites its own teaching. Skim bullets? You get bullets. Learn by story? You get the story. Ace drills? The drills get harder.
- Four registers — concise, visual, story, drill — swapped mid-lesson.
- No settings page — it adapts from how you actually respond.
Entropy, in two lines
- Entropy counts how many microscopic arrangements look the same from outside.
- Systems drift toward high-entropy states because there are simply more of them.
- “Disorder increases” is probability, not preference.
Ordered → disordered
Both are “the same gas” — but almost every arrangement looks like the right box. That ratio is entropy.
The library with no librarian
Imagine a library where every returned book goes on a random shelf. Day one, it's alphabetized — one perfect arrangement. By June, it's chaos, and no one did it on purpose.
There are trillions of “messy” shelf orders and one sorted one. Random returns find mess, not order. That one-way drift — sorted to scrambled, never back — is the second law working on your bookshelf.
Know what you know.
See what you don't.
Every answer updates a live map of your understanding. Weak spots don't hide — they get flagged, queued and re-taught before the exam finds them first.
- Per-concept scores, not course-level averages.
- Decay-aware — mastery fades on the forgetting curve, reviews land first.
Studying that
schedules itself.
Coursity reads your week and plants the right session in the gaps — reviews when mastery is about to fade, drills before the exam, nothing when you're slammed.
- Two-way sync with Google, Apple and Outlook calendars.
- Right-sized blocks — 15-minute drills to 45-minute mock exams.
Your course is one drop away.
