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.
Private, in-browser text and code diff checker with word-level highlighting
Read changes in two columns side by side, or switch to a single-column unified diff in the same format as git diff and patch files.
Darker highlights mark the exact words and characters that changed inside a modified line, not just the lines that differ.
The comparison runs entirely in your browser, so confidential code, contracts and config files never leave your device.
Ignore whitespace, indentation and capitalisation differences, and control how much unchanged context is shown around each change.
