grip duck — Socratic AI LeetCode interview coach

AI interview coach for LeetCode. Locks the editor until you explain your approach, then debriefs every submission. BYO API key.

grip duck is a Socratic AI coach for LeetCode that makes you a better problem-solver, not a faster cheater. It locks the code editor until you explain your approach in plain English. Then it asks one interviewer-style question at a time, never the answer, never the algorithm. After you submit, you get a structured debrief so you actually learn from the problem instead of moving on to the next one. Built for engineers grinding LeetCode for coding interviews and DSA practice who want to build real problem-solving skill, not just pattern-match their way to a green checkmark. Why it works? The hardest part of a real coding interview isn't writing the code - it's reasoning out loud about a problem you've never seen before, while someone watches. Most LeetCode tools skip straight to hints or solutions, so you never rehearse that. grip duck makes you do it on every single problem: state an approach, defend it under questioning, then review what an interviewer would have pushed back on. That is the rep that transfers to the actual interview room. What you get: • Approach gate - the editor stays dimmed until you write your approach in plain English, so you can't shortcut straight to code (the problem statement stays fully readable) • Socratic nudges - the duck asks one pointed question at a time and never hands you the answer, the way a strong interviewer probes your thinking • Debrief on every submission - a clear Approach / Efficiency / Code Style verdict plus the optimal approach and the one idea to take into the next problem • Runtime + memory "beats" stats surfaced inline, when LeetCode shows them • Works on every LeetCode problem, in every language LeetCode supports Bring your own key: Pick the model you trust: Anthropic Claude (recommended; the prompts are tuned for it), OpenAI GPT, or Google Gemini.
