Prompt optimization for Lovable
Quick answer
In Lovable, the mode and the size of the change matter more than the length of your prompt. Lovable bills by the work a request causes, so a shorter prompt is not automatically cheaper. Pick the right mode, ask for one focused change with clear acceptance criteria, and use Typo to trim the filler around it.
Chat, Plan or Build
- Chat discusses your project without changing it. Good for questions and ideas.
- Plan investigates and writes a plan without changing code. Good before a bigger change.
- Build makes the change. Good for one focused, testable step.
Why shorter is not the same as cheaper here
Lovable's documentation describes credits that depend on the mode and on the work performed. A build that touches ten files uses more than one that changes a single component, however short the prompt was. A clear, slightly longer prompt that avoids a second build can be the cheaper choice. Typo never turns characters saved into a credit estimate.
What a focused build request contains
- What to change, named exactly: the page, component or file.
- What must stay as it is: data, routes, the design you like.
- How you will check it: “the form shows an error when the email is empty”.
- What not to do: “do not add new packages”.
At level 3 the greeting, “please” and the sign-off go, and every requirement stays. “Basically” is a level 4 filler word, so it stays too. That is the kind of light touch a build request needs.
Which level for Lovable
Use level 3 or lower for build requests. It removes greetings, “please” and “could you” and leaves your scope and criteria untouched. Higher levels are fine for questions in Chat.
How to use Typo in Lovable
Lovable runs in your browser, and from Typo 0.12 lovable.dev is on Typo's Auto list, so the token language wakes up there by itself. You can also write your prompt and press Ctrl+Alt+T on Windows to shorten it in one go. Ctrl+Alt+Z brings the original back.
