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 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 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 upload images to Lovable?

Q: 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.

Short answer

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).

Attach files in chat

The chat panel accepts file attachments alongside your text prompt. Drop or select an image and tell Lovable what to do with it:

Attached is our logo. Use it in the header, replacing the placeholder text logo. Keep the same height as the current placeholder.

Lovable can use an attached image two ways: as a design reference (a screenshot to match — see /questions/how-do-i-make-lovable-match-a-screenshot) or as an actual asset to be placed in the built app (a logo, product photo, background image).

Say which one you mean

Be explicit, because the same action (attaching a file) can mean either thing:

"Use this as the logo in the header" → asset
"Match this layout" → reference only, don't insert the image itself

Formats and size

Use standard web formats — PNG, JPG, SVG for logos/icons, WebP where you have it. Keep file sizes reasonable; very large images slow down both the chat upload and your app's load time once published. If you need optimisation, you can ask Lovable to add a step for compressing or resizing on upload for user-facing image features.

What usually goes wrong

Uploading a low-resolution or heavily compressed screenshot and expecting a pixel-perfect match — the smaller the source detail, the more guessing Lovable does.
Forgetting to say where the image goes. "Here's an image" with no instruction gets applied inconsistently; name the exact component or section.
Using a placeholder image and forgetting to swap it later. Track any stock/lorem imagery in Project knowledge or a TODO so it doesn't ship live.
Large, unoptimised files bloating the app — ask Lovable to serve images responsively or via a storage bucket (Lovable Cloud storage) rather than baking huge files into the codebase for anything beyond a handful of images.

For a logo specifically, see /questions/how-do-i-get-lovable-to-use-my-logo for placement details.
