Cursor

Tools Intermediate
Definition

A code editor with an AI agent built in, made by Anysphere, now part of SpaceX. A code editor is the program developers write software in; Cursor is a modified version of the most common free one, Visual Studio Code. Type code yourself or hand the agent a whole feature. It is for people who want to see code.

In plain English

If you never look at code, this one is background: it’s what the developers you hire are probably using. Cursor is the editor programmers already used, with an agent sitting in the side panel. You can type code yourself, ask it to change a line, or hand it a whole feature.1 It’s the “I still want to see the code” option.

In the real world

  • The split screen: code on the left, agent chat on the right.
  • A developer saying “tab, tab, tab” because the autocomplete finishes whole blocks.
  • A rules file in the project folder, which is a system prompt for that project.

When to use it

  • You write or read code and want AI beside you, not in place of you.
  • Reviewing what an agent changed before it lands.

When not to use it

You never want to see code. Then the editor is in the way. Use Claude Code or the agent mode in your chat app and let it handle the files.

Good, bad, ugly

  • Good: nothing to learn if you’ve used VS Code. It is VS Code.2
  • Bad: model pricing and usage tiers change often. Read the plan page twice.
  • Ugly: ownership changed in 2026. SpaceX completed its purchase of Cursor in August, so plans now bundle in products like Grok Bot.23
  • Ugly: “tab, tab, tab” accepts code nobody read. That’s vibe coding with a nicer interface.

Key facts

Made by
Anysphere, founded in 2022. Owned by SpaceX's AI company, SpaceXSI, since August 2026.
Based on
Visual Studio Code, the most common free code editor
The difference
The agent lives inside the editor instead of in a separate terminal or chat

Common questions

Is Cursor an AI model?

No. It's an editor that uses models from OpenAI, Anthropic, and others. You pick the model inside it.

Cursor or Claude Code?

Cursor is an editor you work in with an agent beside you. Claude Code is an agent you hand tasks to. People who want to see and touch the code tend to prefer Cursor.

Is it for non-programmers?

Less so. It assumes you want to look at code. If you don't, a chat-first agent is a gentler start.
