Calyxa is an AI math tutor that lives in your browser and actually remembers you. Instead of a chatbot that forgets everything between sessions, Calyxa tracks the specific misconceptions you've hit before, adapts each session to what you've mastered and what's fading, and teaches Socratically, guiding you to the answer instead of handing it over. Built on a real adaptive engine, it calibrates difficulty to you in real time. [Currently math-only, in beta. Free to try / Pro tier at $10.]
Personalized, data-driven SAT preparation. Smart weekly study plans, progress analytics, error tracking, and AI-powered adaptive replanning — all in one place. Completely free and accessible to all students.
