WHY LeetSense? LeetCode's editor is intentionally minimal. LeetSense brings the productivity of a modern IDE directly into your browser without changing the LeetCode experience. • No AI-generated solutions • No code generation • No distractions • Just smarter editing Perfect for developers preparing for coding interviews who want IntelliSense—not answers. SUPPORTED LANGUAGES Support is being added progressively, including: • C++ • Python • JavaScript • TypeScript • And more PRIVACY LeetSense works entirely in your browser. Your code stays on your device and is never sent to our servers. WHAT'S NEW IN 1.1.0 • Faster and more reliable C++ IntelliSense through improved clangd communication. • Reduced C++ startup memory with streaming WebAssembly loading. • Lower idle CPU usage after LeetSense connects to the editor. • Python analysis now starts only when needed and shuts down after inactivity. • More responsive completions, hover information, and signature help. • Improved recovery from temporary extension communication failures.
