Interactive math, coding and AI tutoring you learn by doing
Learn math, science, CS and AI through short, visual exercises that build intuition step by step rather than passive video watching.
A visual, interactive tutor that works on a shared canvas, asks guiding questions and gives hints without simply revealing the answer.
Quizzes and reviews adapt to your level, tracking what you have mastered and resurfacing topics that still need work.
Write and run real code to learn programming logic, algorithms, data structures and debugging skills relevant to the AI era.
Desktop and mobile AI copilot that feeds live answers during coding and system design interviews
The desktop app is designed to remain hidden from Zoom and browser-based screen recording, with moveable overlays and no visible taskbar presence.
Capture any window containing a coding problem and receive a complete solution with syntax highlighting, approach notes and complexity analysis.
Transcribes both your voice and the interviewer's audio so spoken system design and behavioral questions can be answered in the moment.
Pair the desktop app with a phone for remote screenshots, prompts and answers, or use the browser-based mobile mode with no installation.
