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 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.

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 get Lovable to use my logo?

Short answer

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.

Upload, then instruct precisely

Attach the logo image to a chat message and specify every placement you want:

Attached is our logo (SVG). Replace the text logo in the header with this image, height 32px, linking to "/" on click. Also use it as the favicon.

Without a placement instruction, Lovable may only use the logo in the first place it seems relevant, missing the footer, favicon, or loading screen.

Use SVG where you can

SVG scales cleanly at any size and works well for logos used at multiple sizes (header vs favicon vs footer). If you only have a PNG, provide the largest version you have — Lovable can resize down but not add detail back in if it has to scale up.

Common logo spots to cover in one prompt

Header/nav
Favicon (browser tab icon)
Footer
Loading/splash screen if the app has one
Email templates, if you're sending transactional email via Resend or similar

List the ones that matter to you; Lovable won't automatically propagate a logo to every spot in one pass.

What usually goes wrong

Only the header gets updated, and the favicon still shows the default Lovable icon — ask for the favicon explicitly, it's a separate asset from the header logo.
Logo looks blurry because a small or low-resolution source file was scaled up — supply a higher-resolution or vector source.
Logo colour clashes with a dark header — if you have a light and dark version of your logo, upload both and say which goes where.
Aspect ratio distorted — always give a target height (or width) rather than both, so Lovable scales proportionally.

Once placed, check the Preview on both desktop and mobile widths — a logo that fits the desktop header often needs a smaller size or icon-only mark on mobile.
