Paste or upload code and the AI explains it, generates quiz questions about its logic and output, and tests your understanding line by line.
Paste a function, a class, or an entire file — the AI breaks down what it does and then tests whether you really follow it.
Upload code and the AI walks through control flow, data structures, and edge cases in plain language, grounded in the exact source you provided.
It generates questions about a snippet's logic and output — including 'what does this print?' and 'what breaks if this line changes?' — to expose gaps before an exam does.
Drill Big-O, sorting, recursion, and data-structure trade-offs with flashcards and diagrams generated from your lecture notes and readings.
See how language features, patterns, and systems concepts connect across a course, with clickable nodes that link back to cards and explanations.
Paste a snippet, upload a file, or point the platform at lecture slides and problem sets. It ingests source code and prose alike.
The AI annotates the logic, names the patterns, and traces execution so you understand the why, not just the syntax.
Auto-generated quizzes and FastFire drills test recall of behavior, output, and complexity — turning passive reading into active mastery.
Generate flashcards, quizzes, and audio from your own notes — then study with an AI tutor that knows exactly where you're stuck.
