PROMPT GUIDE
Lovable is powerful — but only as good as the prompt you give it. Most people describe their idea in one sentence, get an app that is almost right, and spend hours fixing what a better prompt would have prevented. This guide shows you how to write Lovable prompts that work on the first try, and gives you a free generator that engineers them for you.

Lovable builds React + Tailwind on a Supabase backend. Tell it what users should see and be able to do — not which components or libraries to use. It knows its stack better than you do.
Lovable is strongest at single-feature changes. "Add a login screen" in one prompt, "add a settings page" in the next. Bundle five features and it will half-build all of them.
For auth and database work, ask it to use the Lovable Knowledge Base for Supabase patterns instead of inventing its own. That single line prevents most broken login flows.
End every prompt with "do not modify unrelated code." Without it, Lovable sometimes refactors working screens while adding your new one.
For database changes, name the table and fields precisely. "Add a streak_count integer field to the members table" — never "restructure the backend."
Add [FEATURE] to my app. What it should do: [describe the user-visible outcome in plain words]. Details: - [Concrete requirement 1] - [Concrete requirement 2] - Include the empty, loading, and error states. - Match the existing app's style and layout. For auth/database changes, use the Lovable Knowledge Base for Supabase patterns. Do not modify unrelated code.
Almost always because the prompt bundles several features or buries requirements in a paragraph. Lovable follows focused, single-feature prompts far more faithfully — one ask per prompt, with the requirements listed plainly.
A clear outcome, concrete requirements, the states most people forget (empty, loading, error), and a closing line protecting unrelated code. Our free generator writes all of that for you from a plain description.
Yes — with a free VibePilot account you can attach a design or app screenshot, and the generated prompt rebuilds what is visible: layout, components, styling, and content.
