Prompting best
practices

Five principles that separate great results from frustrating ones.

The difference between people who love Lovable and people who get frustrated usually comes down to one thing: how they prompt. Not how clever their prompts are, but how they think about prompting.

These five principles come from watching thousands of projects succeed (and fail), from our own team's experience, and from community members who've figured out what works. Whether you're building your first project or your fiftieth, these will save you time, save you credits, and get you to a better result.

Principle 1: Know what you're building before you build it

The most common mistake in Lovable isn't a bad prompt. It's prompting too early, before you've really figured out what you want.

This might sound obvious, but it's worth saying: Lovable is incredibly fast at building things. That speed is a superpower, but it can also trick you into skipping the thinking part. And when you skip the thinking, you end up spending ten prompts fixing what one clear prompt could have built right the first time.

You don't need a fifty-page spec. You just need answers to a few questions before you start.

Principle 2: Build one piece at a time

This is the principle that saves the most credits and causes the least frustration. And yet, it's the one people most want to skip.

The temptation is understandable: you have the whole app in your head, you want to get it out. So you write a massive prompt describing every page, every feature, every interaction. Lovable tries its best, but massive prompts overwhelm the model. You end up with something that's half-right in five places and fully right in none of them.

The people who get the best results treat Lovable like building with Lego. A working foundation, then one brick at a time. Each brick does one thing. You check it, you like it, you move on.

Principle 3: Say exactly what you want, and what you don't

If there's one sentence that captures this principle, it's this: tell Lovable what to build, where to build it, and what to leave alone.

That last part, "what to leave alone," is what makes prompting an AI app builder different from prompting ChatGPT. In a regular AI conversation, you only describe what you want. In Lovable, every prompt modifies a living codebase. It will be helpful to be explicit around any parts of the project you do not want the AI to edit.

The fix is simple: be explicit.

Principle 4: Use the right tool for the job

Lovable gives you three distinct ways to interact with your project: Plan mode, Agent mode, and Visual Edits. Each one is designed for a different kind of work. Using the wrong mode for the task is one of the top reasons people burn through credits unnecessarily.

Principle 5: Think in iterations, not in one shot

You are not trying to write the perfect prompt, you are managing a build.

Every prompt you send generates code that becomes the foundation for the next prompt. A shortcut in prompt #3 might cause headaches in prompt #30. A well-structured component in the beginning might save you hours later. This is why the best Lovable users think less like writers crafting a sentence and more like product managers guiding a project.

The short version

If you take away five things from this page:

Plan before you prompt.

Know what you're building, who it's for, and what it should feel like.

Build one piece at a time.

Build iteratively and test as you progress to ensure working versioning.

Be specific, set guardrails.

Say where, say what, and say what not to touch. Use real content. Maintain a Knowledge file.

Use the right mode.

Plan mode for thinking, Agent mode for building, Visual Edit for tweaking. Debug in Plan first.

Think in iterations.

One change, then check. Refactor along the way. When completely stuck, consider starting fresh. Learn from every build.

Good prompting is about building a habit of clear thinking and intentional communication. The better you get at this, the more Lovable can do for you, and the more fun the whole process becomes.
