The AI code editor built around Claude and GPT.
Cursor is a fork of VS Code that bakes AI deeply into the editor. Tab-complete is multi-line and aware of your whole repo. Cmd-K rewrites code in place. Composer agents make multi-file changes.
Choose Cursor when you want AI to feel like a pair programmer rather than a sidebar chat. The free tier is generous; the paid tier removes rate limits on the best models.
Real outcomes, not feature names.
Setup → first result → confident user. Get a certificate when you finish.
Copy-runnable. Tested. With expected output.
Explain the following code to a junior developer who knows the language but not this codebase.
For each significant block:
1. What it does — one short sentence
2. Why it does it that way — the non-obvious reason
3. What would break if it changed
Skip explanations that are obvious from reading. Don't lecture on language basics.

```Refactor the component below.
Goals (in priority order):
1. {{primary_goal}}
2. {{secondary_goal}}
Constraints:
- Don't change the public API
- Don't add new dependencies
- Keep behavior identical — every prop, every state transition, every effect
- If you find a bug, call it out separately — DO NOT silently fix it
Output:
- The refactored code in one block
- A short bullet list of what changed and why (not what stayed the same)
- A separate "Bugs noticed" section if applicable
```
