Cursor

Cursor is a fork of VS Code built around AI. Composer mode edits multiple files at once, Tab autocomplete predicts whole functions, and Claude/GPT live inside the editor with full repo context.

How to use it

  1. Install Cursor, sign in, point it at your repo.
  2. Use Composer (Cmd+I) for multi-file changes; ask in plain English.
  3. Use Tab for fast in-line edits — it predicts the next 5-10 lines correctly most of the time.
  4. Add docs as @Docs references so Cursor knows your stack's APIs.

Who it's for

  • Developers maintaining real codebases (not just prototypes).
  • Lovable users who export their app and want to keep iterating.
  • Indie devs doing the work of a team of three.

Benefits

  • Editor-grade AI with full project awareness.
  • Multi-file refactors that actually work.
  • Bring-your-own-key option for power users.

How it fits the stack

Cursor sits one layer below Lovable. Build fast in Lovable, graduate to Cursor when you need surgical control. Both run on the same Claude/GPT brain.

Example use cases

Lovable handoff

Export your Lovable app, open in Cursor, add advanced features the prompt couldn't reach.

Bug squashing

Paste a stack trace; Composer finds the root cause across 4 files and patches it.

Test generation

Highlight a function, ask for tests; Cursor writes them with realistic edge cases.

Learn the whole stack — together.

Cursor is one of five. The Lab teaches you to wire them into one income system.
