ankify

Capture LeetCode problems and submissions in one click, then review them with spaced repetition and AI quizzes.

ankify helps you remember the LeetCode problems you've already solved: the trick that made it click, the edge case that broke your first attempt, and the complexity argument. CAPTURE IN ONE CLICK Open any LeetCode problem and click Capture. ankify saves the statement, tags, and every accepted and failed submission, including the failing test case with expected and actual output. No copy-paste. REVIEW IN THE SIDE PANEL The side panel shows today's due queue and the problem in your current tab. Take a quiz, flip flashcards, write notes, and rate your recall without leaving LeetCode. QUIZZES BUILT FROM YOUR OWN MISTAKES Each review generates five multiple-choice questions from the problem statement, your failed submissions, your notes, and your saved cards. Every batch covers at least four different angles and always includes a complexity question. SPACED REPETITION THAT SCHEDULES WHOLE PROBLEMS FSRS-6 schedules each problem, not a pile of disconnected cards, and brings it back shortly before you would forget it. Set a daily limit and review by urgency. STUDY COACH ON THE WEB The ankify web app adds a Study Coach that can read your submissions and explain why an attempt failed, plus a memory dashboard that shows which problems are about to slip. BRING YOUR OWN AI KEY Use your own Anthropic, OpenAI, or DeepSeek key. Keys are encrypted before they are stored. The extension signs in with the same Google session as the web app, so there is no token to paste. YOUR DATA Export everything as NDJSON or delete your account from Settings.
