Cursor: the AI-first code editor, explained for working developers

What makes it different

Cursor is a fork of VS Code with AI woven through it rather than bolted on: chat that can see your codebase, edits that span multiple files from a single instruction, and autocomplete that anticipates the next change, not just the next token.

Because it's VS Code underneath, your extensions, keybindings and settings largely carry over — the switching cost is lower than "new editor" suggests.

The features that change habits

Multi-file edit is the headline: describe a change ("rename this prop everywhere and update the tests") and Cursor proposes a diff across files for you to review. It shifts your role from typist to reviewer.

Codebase-aware chat answers questions like "where is authentication handled?" with references to your actual files — faster than grepping when you're new to a project.

Staying effective with it

Review diffs hunks at a time and reject freely. The tool's speed makes it tempting to accept wholesale, and that's how subtle breakage ships. The developers who thrive with Cursor are the ones who got better at reading code, not worse.

Keep your tests close. AI-assisted changes deserve an immediate test run, every time.

Trying it safely

Install it alongside VS Code, import your settings, and use it on a side project for a week before judging. Pricing includes a free tier with limits and paid plans for heavier use — check the current page, as AI tool pricing moves quickly.
