How do I write a good Lovable prompt?

Describe one concrete outcome, give real content and constraints, and say what NOT to touch. Plan first for anything non-trivial, then build in small steps.

How do I get Lovable to follow my design properly?

Give Lovable concrete references — a screenshot, a site to draw from, exact colours and fonts — and store them in Project knowledge so every prompt is checked against the same design rules.

How do I give Lovable a website to use as inspiration?

Paste the site's URL in your prompt and describe which parts to borrow — layout, spacing, tone — Lovable can't literally browse and clone it, so be specific about what you want copied.

How do I get Lovable to copy a design style without copying the website?

Ask for the underlying pattern — layout, spacing, type scale — in your own words and colours, not the site's actual assets, text or exact visual identity.

How do I upload images to Lovable?

Attach images directly in the chat message box — Lovable can use them as design references or as assets to place in your app (e.g. a logo or product photo).

How do I get Lovable to use my logo?

Attach your logo file in chat and tell Lovable exactly where to place it (header, favicon, footer) — it won't guess sizing or position from the file alone.

How do I give Lovable my brand colours?

Give exact hex codes in your prompt or Project knowledge, name which role each colour plays (primary, accent, background), and ask Lovable to apply them via the Tailwind/shadcn theme, not one-off styles.

How do I get Lovable to use a specific font?

Name the exact font (e.g. from Google Fonts) and tell Lovable to load it and apply it across the theme, not just the current page.

How do I stop Lovable changing things I didn't ask it to change?

State explicitly what must stay unchanged in the same prompt, keep requests narrow, and check the diff/preview after each change so unintended edits are caught immediately.

How do I get Lovable to review existing code before making changes?

Ask Lovable directly, ideally in Plan mode, to look at the relevant files or feature first and summarise how it currently works before proposing any changes.

How do I make Lovable ask me questions before building?

Use Plan mode and explicitly ask Lovable to raise questions or ambiguities before building — it's designed to clarify requirements first rather than guess.

How do I get better results from Lovable prompts?

Be specific and concrete, use real content, plan before building complex features, work in small steps, and review each result in Preview before prompting again.

Why does Lovable misunderstand my prompts?

Usually the prompt is ambiguous, references something that doesn't exist yet, or bundles too many changes at once — narrow it, add references, and split it up.

Should I use screenshots when prompting Lovable?

Yes, for layout and visual matching — a screenshot removes ambiguity that words leave open, especially for spacing, alignment and component styling.

How do I make Lovable match a screenshot?

Attach the screenshot, say precisely what to match (layout, spacing, colours, all of it), and iterate with follow-up prompts comparing Preview against the image side by side.

How do I undo a bad Lovable change?

Open Version history and revert to the version saved right before the bad change — every change Lovable makes is auto-saved as a version, so you can step back without losing later unrelated work.

How do I safely make large changes to a Lovable project?

Plan the change first, bookmark a known-good version before starting, break it into small ordered steps, and check Preview between each step so you can revert cleanly if one goes wrong.

How do I make Lovable build one feature at a time?

Short answer

Ask for one clearly-scoped feature per prompt and confirm it works in Preview before moving on — bundling several features into one message makes failures harder to isolate and revert.

Scope each prompt to one testable unit

A "feature" that's safe to build in one prompt is something you can check in a minute or two: a form, a page, a filter, a button's behaviour. If your request needs "and then" more than once, split it:

Add a contact form on /contact with name, email, message fields, and a submit button that shows a success message. (One message.)

Then, separately once that works:

Now send the contact form submissions to my email using Resend. (Second message.)

Confirm before stacking

Check the Preview after each step. If it works, move to the next feature. If a later step breaks something, you know exactly which prompt caused it, and Version history lets you revert to the version right before it.

Use Plan mode for anything with several moving parts

If a feature genuinely needs multiple connected pieces (e.g. auth + roles + a protected dashboard), use Plan mode first to get Lovable to break it into an ordered sequence of steps, then approve and build them one at a time — see /questions/how-do-i-get-lovable-to-plan-a-feature-before-building-it.

What usually goes wrong

One prompt asks for five unrelated things. If it half-works, you can't tell which part failed, and undoing it undoes everything.
Features that depend on each other are built out of order. E.g. asking for "a dashboard that shows user data" before authentication and roles exist. Sequence dependencies first: auth → roles → protected routes → feature.
Skipping the check-in step. Building three features back-to-back without previewing between them means errors compound and get harder to trace.
Confusing "small" with "trivial". A one-field form is small; "add payments" is not one feature, it's several (checkout UI, Stripe connection, webhook handling, confirmation email) and should be planned and split accordingly.
