LeetHelp

Progressive hints for LeetCode, Codeforces, HackerRank, AtCoder and CodeChef. Code rating and a 100-pattern DSA reference.

LeetHelp is a browser extension for competitive programming that tries hard not to spoil the problems you're working on. Five progressive hint tiers, from a Socratic nudge to the full solution. You pick the depth. Stop before it gives the game away. WHAT'S INSIDE - Hints in five tiers: Nudge, Concept, Approach, Pseudocode, Full Solution. - Dialogue: chat with the model, grounded on the scraped problem. - Instruments: rate my solution (per-axis grade card), review my code, convert to another language, analyze complexity, generate edge cases, list related patterns. - Reference: a browsable DSA library with about 100 patterns and Python templates. Search + eight-chapter filter. Doubles as retrieval that grounds the hints. - Three themes: warm notebook (default), clean modern, or an IDE-style Codey theme. BRING YOUR OWN KEY Paste an OpenAI, Anthropic, Gemini, Groq, or OpenRouter key in Settings. Keys are stored in chrome.storage.sync and only sent to the provider they belong to.
