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 make Lovable build one feature at a time?

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.

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 tell Lovable to only edit one section?

Name the exact page, component or element (or select it via the preview toolbar) and explicitly say the rest of the app should stay unchanged.

How do I get Lovable to plan a feature before building it?

Switch to Plan mode and describe the feature there — Lovable will ask questions and lay out a structured plan for you to approve before any code is written.

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.

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.

Should I use screenshots when prompting Lovable?

Short answer

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

Screenshots remove guesswork words leave in

Describing a layout in text ("cards in a row with the image on top and a button at the bottom") leaves spacing, proportions and alignment to interpretation. A screenshot pins those down directly. Attach it with a specific instruction:

Match this screenshot's card layout for our product grid. Use our own product data and colours, not the ones shown.

When a screenshot helps most

Matching a specific existing screen (yours or a reference) exactly
Reporting a visual bug ("this is misaligned — see screenshot")
Showing spacing/sizing that's hard to describe precisely in words
Communicating a design you've been sent by a client or designer

When a screenshot isn't enough alone

It won't convey interactive behaviour (hover states, animations) — describe those in words alongside it.
It can't tell Lovable your actual content — pair it with real copy and data, not the screenshot's own text.
Low-resolution or cropped screenshots limit what detail Lovable can pick up — capture full elements, not partial crops, where possible.

What usually goes wrong

Screenshot given without instructions. An image on its own is a reference, not a command; say explicitly what to copy from it (layout only? colours too? exact spacing?).
Expecting Lovable to lift and reuse the exact assets in the screenshot (someone else's photos, logo, copy) — see /questions/how-do-i-get-lovable-to-copy-a-design-style-without-copying-the-website for the difference between style and content.
One screenshot for a multi-screen flow. If you're describing a whole user journey, either send a screenshot per screen or be clear the screenshot is only for one part of it.

For matching a screenshot precisely, including follow-up correction rounds, see /questions/how-do-i-make-lovable-match-a-screenshot.
