Lovable turns plain-English prompts into full-stack web apps, with a built-in backend, publishing, and an optional connection to your own Supabase project. These prompts use its Build, Chat, and Plan modes, project Knowledge, and security scans.
Copy the prompt, paste it into the tool's chat, and replace everything in [BRACKETS] with your own details.
1 Write Your Project Knowledge
What it's for: Writing the standing instructions Lovable follows in every request.
When to use it: At the start of a project, or when Lovable keeps drifting from your style or goals. Paste the result into Project settings → Knowledge.
Help me write the project Knowledge for my Lovable app. Keep it under 250 words.
App: [APP IDEA]
Who it's for: [TARGET USER]
Look and feel: [e.g. "calm, minimal, lots of white space"]
Rules: [e.g. "every table needs row-level security", "don't change the navigation without asking"]
Format it as short sections: Product, Audience, Design rules, Build rules.
Tips: Update it whenever you make a big decision, so you don't have to repeat yourself in chat.
What it's for: Getting a plan you can edit and approve before any code changes.
When to use it: The change is large or risky (a new data model, payments, user roles). Switch the mode picker to Plan.
I want to add [FEATURE]. Investigate the project and write a plan.
Users should be able to: [WHAT THEY CAN DO]
Data involved: [e.g. "orders linked to each user"]
Include the screens to add or change, any new tables and who can access them, and the build order. Ask me questions if anything is unclear.
Tips: Plan mode never changes your code. Use Chat mode for quick questions, and Build mode once you've approved the plan.
What it's for: Checking that each user can only see their own data, using Lovable's backend and security scan.
When to use it: Before you publish, or when the Quick security scan flags database issues.
Check my app's database security. Don't change anything yet.
Private data in my app: [e.g. "each user's notes and profile"]
Public data: [e.g. "published posts" / "none"]
Please:
1. List every table and whether row-level security is on.
2. For each table, explain in plain English who can read, add, edit, and delete rows today.
3. Flag anything that lets everyone through, or that doesn't match what I described above.
4. Propose fixes one table at a time and wait for my go-ahead.
Tips: The Quick scan runs automatically each time you publish. You can also run a Deep scan to review your app's code. Both help catch common issues but don't replace a full security review.
What it's for: Finding the cause of a bug before Lovable starts changing code.
When to use it: The same error keeps coming back after "fixes". Use Chat or Plan mode, which don't touch your code.
This keeps failing: [ERROR OR WHAT HAPPENS]
It started after: [RECENT CHANGE or "not sure"]
Don't change code yet. Tell me the 3 most likely causes, how to check each one, and which to try first. Then wait.
Tips: If a change made things worse, open version history from the Chat actions menu and restore an earlier version.
What it's for: Publishing your app and connecting a custom domain, with a pre-launch check first.
When to use it: Your app works in preview and you're ready to share it.
I'm ready to publish. First, give me a short pre-launch checklist for this app: anything still using test data, broken links, missing empty or error states, and anything the security scan flagged.
Then help me publish to [SUBDOMAIN].lovable.app and walk me through connecting my domain [DOMAIN].
Tips: Custom domains are available on paid plans and are managed in Project settings → Domains. Lovable shows a confirmation before it buys or connects a domain.
