About
Cursor is an AI-first code editor founded in 2022 by a small team of MIT researchers, built as a fork of Visual Studio Code with native large-language-model intelligence woven directly into the editing experience. Its mission is to make software engineers dramatically more productive by embedding AI reasoning into every layer of the IDE — from autocomplete to multi-file edits to natural-language code generation — rather than bolting AI on as an afterthought.\n\nThe platform centers on a VSCode-compatible editor that developers can adopt with zero workflow disruption, layering in features like Tab (predictive multi-line completion), Chat (context-aware in-editor assistant), and Composer (autonomous multi-file refactoring agent). Cursor reads and indexes entire codebases, allowing it to propose changes that span dozens of files coherently. It supports all major languages, integrates with existing extensions, and lets teams configure which underlying model — GPT-4o, Claude, or others — powers suggestions. Fortune 500 engineering teams adopt it alongside individual developers, and it is used by more than half of Fortune 500 companies.\n\nCursor reached $2 billion in annualized recurring revenue by early 2026 and raised at a $29.3 billion valuation, cementing its position as the dominant commercial AI coding tool. The company raised $2.3 billion in total funding and is widely regarded as the category-defining product in agentic IDE software, outpacing GitHub Copilot on developer mindshare metrics in multiple surveys.
