Cursor is a code editor built around AI assistance. It can answer questions about a codebase, suggest edits, generate code, and help developers navigate implementation tasks.
In practice
Cursor is popular because it brings AI into the editor workflow. Developers can ask questions with project context and apply AI-generated changes more directly than in a separate chat app.
What to watch
Editor AI can make broad changes quickly. Review generated diffs, understand dependencies, and keep source control clean.
