Short answer: Lovable works best from one long, complete first message — not a conversation. Describe the whole app in that single prompt: who uses it, every screen, the data it stores, the stack (React + Tailwind + Supabase) and a numbered build order. Lovable is a web builder, so ask for a mobile-first responsive web app, never an App Store binary. If you write it well once, you skip the ten follow-up messages that cost you credits.

What Lovable actually does well
Lovable is a chat-based builder aimed at people who do not code. It generates a real React + Tailwind app, wires up Supabase for database and login, and deploys with one click. The UI it produces is genuinely good-looking out of the box — better than anything you would hand-build in the same afternoon.
Where it struggles is scope: the bigger the idea, the more it guesses. A prompt like "make me an app to find tennis partners" leaves it inventing your screens, your database and your rules — and it invents them differently every time you hit regenerate.
Why most Lovable prompts fail
Because they describe a vibe instead of a specification. Lovable has no memory of your head: it does not know which fields a profile needs, who can edit an event, or that the map screen is the third tab. Every unanswered question becomes a decision it makes for you — and then you spend your credits correcting it.
Each retry is a file rewrite. Ten vague messages in, you have a Frankenstein project: three generations of the same component, two naming conventions, and a database schema you never chose.
The 7 blocks of a Lovable-ready prompt
| Block | What goes in it |
|---|---|
| 1. App in one line | What it is, for whom, and what the user gets. "A web app where neighbours lend tools to each other." |
| 2. Users & roles | Who logs in and what each role can do: visitor, member, admin. Lovable needs this to build authentication correctly. |
| 3. Screens | Every screen, in order, with what is on it. Name them the way you want to see them in the app. |
| 4. Data | The tables and their fields — items(id, title, owner_id, status, photo_url). This is the block everyone skips and the one that costs the most retries. |
| 5. Stack | React + Tailwind + Supabase (Lovable's native stack). Say it explicitly so it does not invent a backend you cannot host. |
| 6. Design | Look and feel: mobile-first, dark or light, one accent colour, big touch targets, empty states. |
| 7. Build order | 1) scaffold and layout, 2) auth, 3) main screen, 4) the rest, 5) polish. Lovable follows an explicit order better than an implied one. |
Make an app for lending tools between neighbours. It should look nice and have a map.Prompt that ships
Build a mobile-first web app called ToolShare where neighbours lend tools to each other. React + Tailwind for the UI, Supabase for database and auth. Dark theme, single accent colour, big touch targets, one column on mobile. Users and roles: - Visitor: can browse items but must log in to request one. - Member: can list their own items, approve or reject requests, see their lending history. - Admin: can remove reported listings. Screens (in this order): 1. Login / signup (email + magic link) 2. Browse: grid of items with photo, title, distance and status 3. Item detail: photo, description, owner, "Request to borrow" button 4. My items: list with status (available / lent / pending) 5. Add item: form with photo upload, title, description, category 6. Requests: incoming requests with Approve / Reject 7. Profile: name, area, reviews received Data model (create these tables with row level security): - profiles(id uuid, name, area, avatar_url) - items(id uuid, owner_id, title, description, category, photo_url, status, created_at) - requests(id uuid, item_id, requester_id, owner_id, status, message, created_at) - reviews(id uuid, item_id, from_id, to_id, rating, comment) Rules: - Only an item's owner can edit or delete it. - A request can be created only by a logged-in user who is not the owner. - Items with status "lent" cannot receive new requests. Build order: 1) layout and navigation, 2) Supabase auth, 3) items table and browse screen, 4) add item with photo upload, 5) requests flow, 6) profile and reviews, 7) empty states and loading skeletons.
Lovable-specific rules
- One message, the whole app. Lovable is at its best with a single detailed prompt. Splitting your vision into ten messages produces ten half-built features.
- Name the tables and the policies. If you do not, you will get a schema of its invention plus security rules you cannot audit.
- Ask for web, not native. Lovable ships web apps; a "mobile app" request ends in a confusing PWA conversation.
- Say "mobile-first, responsive". Its default desktop layout is fine but your users are on phones.
- Keep it inside its stack. React, Tailwind, Supabase — no custom servers, no native modules, no exotic database.
- Finish with the build order. It turns a wall of requirements into a sequence, and it is the single easiest quality upgrade you can make.
Checklist before you press send
- Can a stranger read your prompt and build the app without asking anything?
- Does every screen have a name and a purpose?
- Does every table have its fields and its access rules?
- Is the stack named?
- Is there a numbered build order?
- Have you said what happens when there is no data yet?
Six "yes" answers and you are ahead of 95% of Lovable prompts. Any "no" is a retry you are about to pay for.
Or let Inputo write it for you
Inputo is a free wizard that asks you the seven questions above — one screen at a time, in plain language, no jargon — and hands you back the complete master prompt, tuned for the exact tool you are going to use. Lovable gets one long, structured message instead of a vague idea.
It takes about three minutes. The first steps are free, and the full prompt is €5/month (or €5 once for 7 days if you would rather not subscribe — you are building a project, not running a company).

Frequently asked questions
How long should a Lovable prompt be?
Long enough to answer every question Lovable would otherwise guess: roles, screens, data, stack and build order. In practice that is 300 to 700 words. A one-line prompt is not shorter work — it is just work moved into ten paid retries.
Can Lovable build a mobile app?
It builds responsive web apps. You can install those on a phone home screen as a PWA, but Lovable does not produce an iOS or Android binary for the App Store. If you need a store app, that is a different tool.
Should I use Lovable's own "prompt enhance" button?
It helps with wording, not with thinking. It cannot invent the decisions you have not made — which screens exist, what a member can do, which fields your table needs. Decide those first, then let any tool improve the phrasing.
Do I need to know how to code?
No. But you do need to know what you want built. That is the part Inputo exists for: it turns "an app for lending tools" into the specification Lovable needs.
