The AI used credits but nothing changed in my project.

If the AI used credits but nothing visibly changed in your project, here are a few things to try:

1. Revert and retry — Use the version history to revert to a previous version and try a different, more specific prompt. Nothing gets lost; all changes stay in chat and can be reapplied.
2. Check the message cost — Click the three dots beneath the message to see how many credits it used. Some complex prompts may consume credits even if the result isn't what you expected.
3. Refine your prompt — Be more specific about what you want changed. Clearer prompts tend to produce better results.

Credits are consumed based on message complexity, and unfortunately there are no refunds for messages that don't produce the desired outcome. If you believe there's a bug, contact support@lovable.dev.
