About

Composer is Cursor’s custom-built agentic AI model optimized specifically for software engineering tasks and designed to power fast, interactive coding assistance directly within the Cursor IDE, a VS Code-derived editor enhanced with intelligent automation. It is a mixture-of-experts model trained with reinforcement learning (RL) on real-world coding problems across large codebases, so it can produce high-speed, context-aware responses, from code edits and planning to answers that understand project structure, tools, and conventions, with generation speeds roughly four times faster than similar models in benchmarks. Composer is specialized for development workflows, leveraging long-context understanding, semantic search, and limited tool access (like file editing and terminal commands) so it can solve complex engineering requests with efficient and practical outputs.

About

Pencil.dev is an AI-powered design-in-code canvas and creative tool that brings visual interface design directly into development environments like Cursor, VS Code, and other IDEs so designers and engineers can work without handoffs between tools. Built around an agent-driven MCP (Model Context Protocol) canvas and an open design format that lives in your codebase, Pencil lets you draw, iterate, and generate pixel-perfect UI screens with AI assistance while keeping the design files versioned in Git alongside your source code, enabling branches, merges, and rollbacks like regular code. It eliminates the friction of switching between tools by embedding a Figma-like canvas into the IDE, supports importing frames and assets from Figma with vectors and styles intact, and lets you manipulate design elements directly with familiar editing panels, layers, and CSS-like properties, while AI models help generate screens, flows, and components in parallel.
