What consumes a credit
Credits track AI work, not app size or traffic.
Consumes credits
- Any prompt that changes your project.
- Follow-up messages fixing a failed build.
- Large multi-feature requests, proportionally more.
Free
- Viewing the preview, refreshing it, sharing it.
- Publishing and re-publishing.
- Every visitor to your live site, forever.
Why one prompt costs more than another
The AI must read the relevant files, decide on changes, write them, and check the build. "Rename this button" touches one file. "Add multi-tenant billing with invoices and an admin view" touches dozens, and if it fails you pay again for the repair.
Cost scales with scope and blast radius, so the cheapest way to build a big feature is as a sequence of small, verifiable ones.
The routine that cuts usage most
1. Plan before you prompt. Write your screens and tables in a text file first. Ten minutes of planning routinely saves more credits than any prompting trick.
2. Use chat before build. Ask "what's the best way to model bookings that repeat weekly?" and read the answer before spending a build message on the wrong structure.
3. One change per message. Verify the preview, then continue. Small diffs fail less and are cheap to reverse.
4. Be specific about the target. Name the page, the component, the colour, the number. "Make the hero heading 48px on desktop and 32px on mobile" beats "make the hero nicer" and never needs a second attempt.
5. Never re-prompt a failure the same way. After two failed attempts, stop. Paste the exact error text and ask: what is causing this error, and what are the options? Diagnose, then fix once.
6. Lock what must not change. "Do not change the header, the routing or the database schema" prevents collateral edits you then pay to undo.
7. Reuse instead of recreating. "Build this new page using the same card component as the pricing page" is cheaper and more consistent than a fresh design.
Where beginners lose the most credits
| Habit | Cheaper alternative |
|---|---|
| "Make it look better" | Name the exact spacing, colour and size |
| Rebuilding a broken feature from scratch | Revert to the last good version, then make one small change |
| Styling before the structure is settled | Structure first, style once |
| Asking for five features in one message | Five messages, verified one at a time |
| Guessing at an error three times | Paste the error, ask for a diagnosis |
Use version history as a credit tool
Reverting is far cheaper than repairing. If a change made things worse, roll back to the last working version and retry with a tighter prompt. Builders who revert freely spend noticeably less than builders who keep patching.
Do credits carry over?
Treat monthly allowances as use-it-or-lose-it and daily free limits as a reset. Plan a build session around what you have rather than assuming a bank balance, and always leave a margin for fixes — every project needs some.
The mindset shift
Credits reward clarity. The same finished app can cost wildly different amounts depending on how precisely you asked for it. Write prompts the way you would brief a contractor: what to change, where, what the result should look like, and what must not be touched.
Frequently asked questions
- What is a Lovable credit?
- A unit consumed when you send a message that makes the AI read your project and change code. Bigger requests consume more than small ones.
- Do previews and published visitors use credits?
- No. Previewing, publishing and site traffic are free; only AI messages that change the project consume credits.
- Why did one prompt use so many credits?
- It touched many files, or it failed and needed repair. Multi-feature prompts and blind retries after errors are the two biggest consumers.
- What is the fastest way to reduce credit usage?
- Plan screens and tables first, prompt one specific change at a time, and paste exact error text instead of retrying the same request.
