lemmarisAnswers you can check
Answers are computed, not guessed by a chatbot. Each step says what checked it, and when something cannot be checked, Lemmaris says so instead of bluffing.
Hard engineering courses, one short lesson at a time.
Chip makes tough engineering ideas easier to explore with guided lessons, live explanations, and answers a solver can check. Lemmaris is for engineering learners everywhere; we’re starting with UT Austin courses.
Lessons you can touch
Chip explains on a live canvas. Change a resistor, step through a circuit, and watch the idea move while he talks.
Stop him and ask
Interrupt at any point. Asking for help never blocks you. You just get a fresh question afterward, so you still prove it yourself.
A little every day
Short lessons, streaks, daily quests and XP keep you coming back between problem sets.
Our starting course catalog
We’re beginning with six UT Austin electrical and computer engineering courses. They open for learners with a verified UT email address; a free sample lesson is open to everyone, and Lemmaris is growing for engineering learners everywhere.
