The 'AI builder timeout' error in Lovable means the AI took too long to generate code and the request was killed. This happens with complex prompts, large projects, or during server overload. Simplify your prompt into smaller steps, reduce the scope of changes requested, and retry. If the issue persists, check Lovable's status page for active incidents.
What does "AI builder timeout — please try again" mean in Lovable?
When Lovable shows this timeout error, the AI generation process exceeded the maximum allowed processing time. Unlike the 'stuck on Thinking' state where no processing occurs, a timeout means the AI was actively working but could not finish in time. The request is terminated and you need to retry.
Timeouts are more common with complex prompts that ask for multiple features, large projects with many existing files that the AI needs to analyze, and during peak usage times when Lovable's servers are under heavy load. The AI needs to read your entire project context, plan the changes, and generate code — all within the timeout window.
This error can consume credits even though no useful output was produced. Lovable has partially addressed this by making 'Ask the AI to fix' messages free, but initial generation timeouts may still be counted. The pattern of timeout followed by retry followed by another timeout can quickly burn through credits on complex projects.
Common causes
The prompt requests too many
changes at once, requiring more AI processing time than the timeout allows
The project has grown large with
many files, increasing the time the AI needs to analyze existing code before generating changes
Lovable's servers are under heavy load during
peak hours, reducing available processing capacity per request
The prompt is ambiguous or
contradictory, causing the AI to spend excessive time trying to reconcile conflicting requirements
The project has accumulated errors or
broken dependencies that the AI tries to resolve alongside the new request
A previous failed generation left the project in
a partially modified state that is more complex for the AI to work with
How to fix "AI builder timeout — please try again" in Lovable
The most effective fix is to simplify your prompt. Break complex requests into smaller, focused tasks. Instead of asking for an entire feature with UI, API integration, and database operations in one prompt, split it into separate steps: first the UI layout, then the data fetching, then the database writes.
If your project is large, help the AI by being specific about which files to modify. Use @file syntax to scope the AI's attention to specific files rather than making it analyze the entire project. For example: '@src/components/Dashboard.tsx Add a bar chart showing monthly revenue.'
Check Lovable's status page for active incidents. With 30+ incidents between December 2025 and March 2026, outages are not uncommon and can cause timeouts even for simple prompts.
If the same prompt keeps timing out, try rewording it to be more direct and less open-ended. Provide specific technical details about what you want rather than describing the feature at a high level. The AI processes specific instructions faster than vague requirements.
As a last resort, if your project has become too complex for Lovable to handle reliably, consider duplicating the project and working from a clean copy, or reverting to the last stable version before the issues began.
Prevention tips
- Break complex prompts into 3-5 focused steps rather than requesting everything in a single prompt — smaller tasks complete within the timeout window
- Use @file syntax to scope the AI's attention to specific files, reducing the amount of project analysis needed before generation begins
- Check Lovable's status page before retrying multiple times — persistent timeouts during peak hours may indicate a server-side issue
- Revert to the last working version if your project has accumulated errors that are making every prompt timeout

Lovable keeps showing 'AI builder timeout — please try again' when I try to add a new feature. My project has about 40 files. How do I break my prompt into smaller steps that won't timeout?
My Lovable project times out whenever I try to add features. Here is what I'm trying to build: [describe feature]. Break this into the smallest possible Lovable prompts that will each complete without timing out.
Frequently asked questions
Why does Lovable show "AI builder timeout — please try again"?
The AI generation exceeded the maximum processing time. Common causes are complex prompts requesting multiple features, large projects requiring extensive analysis, and server overload during peak hours. Simplify your prompt and retry.
Does Lovable charge credits for timed-out generations?
It depends. Initial generation attempts that timeout may still consume credits. Lovable has made 'Ask the AI to fix' messages free, but the initial timeout may be counted. Check your credit usage in account settings and contact Lovable support if you believe credits were unfairly consumed.
How do I prevent AI builder timeouts in Lovable?
Break complex requests into small, focused prompts. Each prompt should request one specific change. Use @file syntax to scope the AI to specific files. Avoid prompts that describe entire features — instead, build incrementally with separate prompts for UI, logic, and data.
Can a large project cause more timeouts in Lovable?
Yes. Larger projects with more files require more analysis time before the AI can generate changes. This increases the chance of hitting the timeout. Use @file references to help the AI focus on specific files, and keep your project organized to minimize unnecessary complexity.
What should I do if every prompt times out in my Lovable project?
First check Lovable's status page for outages. If no outage, try a very simple prompt like 'Change the header color to blue' to confirm the project itself is not the issue. If simple prompts work, the problem is prompt complexity. If nothing works, duplicate the project and try the duplicate.
Can RapidDev help with Lovable projects that keep timing out?
Yes. RapidDev can analyze your project structure, identify what is causing timeouts, and help restructure your approach. For complex applications that have outgrown Lovable, RapidDev can migrate the project to a custom development workflow with better reliability.
