LeetCode Assistant

Tracks problem solving and provides insights on LeetCode

LeetCode Assistant — learn faster with mentor-style help (without losing the practice) What it is LeetCode Assistant is a companion for leetcode.com problem pages. It adds a small floating panel that gives you structured support while you solve: a mentor-style hinting flow tied to your solving context, plus a compact dashboard that helps you interpret your recent attempts and what to revisit. Who it’s for Developers who want hints that feel like a coach (what to check next, common pitfalls, invariants) rather than immediately jumping to a finished solution. People who solve a lot on LeetCode and want a clearer sense of what’s “good enough” vs “needs another pass” for the current problem. Anyone who benefits from lightweight review signals (revisit vs solid) without leaving the problem page. What you get (features) 1) Mentor-style hints (concept-first) The assistant is designed to steer you with one deeper hint at a time, grounded in your session context (your code, errors, and progress). The goal is practice quality: keep you thinking, reduce “stuck loops,” and highlight the type of misunderstanding that’s causing failure—without turning every click into a spoiler. 2) A practical “this problem” dashboard Open the assistant to see a summary focused on the problem you’re currently on, including a simple verdict-style read like “solid for now” vs “needs revisit”, based on signals from your recent submissions and performance context. This is meant to answer a very practical question fast: should I move on, or should I schedule a second pass? 3) Topic / practice awareness (from your activity) The dashboard can also surface patterns from your recent solving activity so you can notice what you’ve been practicing lately. It’s not a replacement for LeetCode’s full analytics; it’s a lightweight on-page nudge to stay oriented. 4) Revisit workflow support (bookmark list sync) When a problem is flagged as worth revisiting, the extension can help you keep that organized by syncing with your LeetCode bookmark/favorite workflow (so “revisit” becomes an action, not a vague feeling). 5) Built for the page you’re already on Everything is designed to stay inside the LeetCode problem experience—open the panel, get help, close it, keep solving. Why install it (the value in one sentence) Because it turns “I’m stuck” and “am I done?” into actionable next steps and a clearer revisit decision, without forcing you to bounce between tabs and notes. How it works (plain English) You install the extension and open a LeetCode problem. The extension shows a small launcher on the page. When you request help, it sends the necessary context to your hosted backend API to generate structured guidance. The extension may also read LeetCode page/session context (within the permissions you approve) to compute insights like submission health and practice patterns. You see results in the overlay: hints, optional deeper help when appropriate, and dashboard summaries. What this is not It’s not a promise to “solve every problem instantly.” It’s not a replacement for reading problem statements, implementing yourself, and learning from failed cases. It’s not guaranteed to match every LeetCode UI change forever; LeetCode evolves, and extensions may need updates over time. Privacy & permissions (what you should expect) Network access The extension communicates with: leetcode.com (your active learning site) Your configured backend host (for hinting and related features) This is expected for an assistant that combines on-page context with server-side model calls. Account / session Some features rely on you being signed into LeetCode similarly to how normal site features work. Treat your LeetCode session as sensitive; avoid sharing tokens or cookies. Data handling Assume your solving context may be transmitted to your backend to generate guidance. If you publish this publicly, communicate clearly what is stored (if anything), for how long, and who operates the server. Reliability notes (free hosting) If you use a free cloud tier, services can sleep after inactivity. The first request after sleep may take longer. That’s normal for free hosting and doesn’t mean the product is “broken”—it’s just cold starts. Getting the best results (quick tips) Run attempts normally so the assistant can reason from real outcomes, not guesses. Use hints as steering: try a small change, re-run, iterate. If you’re serious about retention, pair the “revisit” signals with your own schedule (same-day review vs next-day review). Support / feedback mindset If something breaks after a LeetCode site update, note the problem URL and what panel action failed; that’s usually enough to reproduce and fix extension-side selectors or flows. Final note If your goal is disciplined practice—understanding why things fail, tightening your approach, and knowing what deserves a second pass—this assistant is meant to reinforce those habits directly where you solve. (This block is intentionally long-form for a 16,000-character field; if you paste it and hit a limit anyway, truncate from the bottom upward—starting with “Reliability notes” and “Getting the best results.”)
