Auto-track submissions, organize by patterns, and get AI-powered notes — your smart LeetCode notebook. 🚀 LeetBook — Your AI-Powered LeetCode Companion Stop losing track of your LeetCode progress. LeetBook automatically captures every accepted submission and builds a personal knowledge base — so you can focus on solving, not note-taking. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✅ AUTO-TRACK SUBMISSIONS Every accepted solution is captured instantly — code, language, runtime, memory, and timestamp. No copy-pasting. No manual logging. Just solve and go. Solving on another site? Add problems manually from Codeforces, HackerRank, GeeksforGeeks, or anywhere else. 🤖 AI-POWERED STUDY NOTES Get instant AI analysis on every submission: • Key algorithm patterns identified • Step-by-step dry-run walkthrough • Time & space complexity breakdown • Notes you can review anytime Powered by Groq or Google Gemini (bring your own API key — stored locally, never on our servers). 📝 RICH-TEXT NOTES Write your own notes in a clean editor — no markdown to learn. Paste from LeetCode and headings, lists, tables, and code blocks keep their formatting. Type # to link one of your submissions, like linking a work item; click the link to jump to it, or Ctrl/Cmd+click to open it on LeetCode. 🏷️ PATTERNS, TOPICS & TAGS Organize problems by 50+ algorithm patterns — Two Pointers, Sliding Window, Dynamic Programming, BFS/DFS, and more — plus your own topics and tags. See which patterns you've mastered and where you need practice. 🔍 SEARCH, SORT & EXPORT Query your problem library like a pro: • Filter by difficulty, pattern, topic, and tags • AND/OR logic with operators like "in", "not in", "contains", "is empty" • Save and reload your favorite views • Sort by last accepted, last modified, date created, title, or difficulty — your choice is remembered • Export exactly what you're viewing to CSV, ready for Excel or Google Sheets 📊 STATS & INSIGHTS Track your momentum — total solved, problems solved in the last 7 and 30 days, current and best streaks, difficulty mix, and your top patterns. 🌗 DARK & LIGHT MODE Beautiful Google Material design with full dark mode support. Follows your system preference or set it manually. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 PRIVACY FIRST • API keys are stored locally on your device — never transmitted to our servers • CSV exports are created in your browser and saved straight to your device • Sign in with Google — your data is yours • No ads, no tracking, no data selling 📖 HOW IT WORKS 1.
