Cursor does not need a pretty prompt: it needs context
Cursor is an AI editor working on a real repository. Unlike a browser builder such as Lovable or Bolt, the value is not generating an app from scratch — it is changing existing code without breaking what already works. For that, context matters more than wording.
Spend the first message of a session describing the project: what the application is, who uses it, the stack, how folders are organised, the conventions (naming, styling, interface language) and what must not be touched. Everything that follows in the session inherits that context.
The three prompt levels in Cursor
- Project level. The opening message. Stack, structure, conventions, limits. It does not request changes: it prepares the session.
- Change level. One request per thing. "In src/pages/Invoice.tsx, when VAT is 0 the total shows NaN; it should show the subtotal."
- Criteria level. What done means and what is forbidden. "No new libraries", "do not change the database schema", "all copy in English".
A template for asking Cursor for a change
Notice it is three sentences: situation, change, limit. That structure produces the smallest diffs and the fewest undo cycles.
Mistakes that cost an afternoon
- Three requests in one message. Cursor edits files as it goes: if you dislike the result you cannot tell which part to reject.
- Not naming the file. "Fix the login" across 200 files is an invitation to edit the wrong one.
- No do-not-touch list. Without limits the model "cleans up" things that were working.
- Accepting diffs unread. Ten seconds of reading saves an afternoon of debugging.
- Starting a project without a spec. Cursor accelerates people who already know what they are building; it does not decide the product for you.
Cursor when you do not write code
It is possible, with realistic expectations: installing the editor, opening a folder and describing changes is manageable. What does not disappear is needing to understand what you are changing — folders, a terminal and reading code are still there. If the goal is shipping an idea this week without touching code, start with Lovable or Bolt.new, and move to Cursor when the project demands more control.

Frequently asked questions
How do you write a good prompt for Cursor?
At three levels: a project message when the session starts (stack, structure, conventions), one request per change naming the file and expected behaviour, and an explicit limit on what must not be touched.
What is the best way to prompt Cursor for small changes?
One change per message, naming the file and describing before and after. Small requests produce small diffs, and a small diff can be reviewed or rejected without dragging the codebase along.
Is Cursor useful if I cannot code?
It is, but it does not remove the fact that you work on code: folders, a terminal and files worth reading are still there. As a first tool a browser builder is faster; Cursor is a better second tool.
What is the difference between Cursor and Lovable for building an app?
Lovable generates the whole app in the browser with Supabase and hosting; Cursor is an AI editor over code that already exists. Lovable to reach something showable sooner, Cursor to maintain and extend it.
How do I stop Cursor changing code that already works?
Say so in the message: do not touch X. And read the diff before accepting. Adding project conventions to the session context also reduces unnecessary edits.
Is this Cursor prompt generator free?
Yes — free, no signup, with a limit of 8 prompts per hour per IP. No account or card needed.
