Question 1

Revert a change or edit a message and revert to use a different approach

Accepted Answer

Edit or revert specific changes in your chat history. Click the revert option under each response, or use the View History tab to restore an older version. This creates a new edit card, so all your history is preserved.

Question 2

Can I see what Lovable is doing while it works?

Accepted Answer

Yes, you can watch Agent mode execute in real-time. See your code update, preview render, and logs populate as it works. This transparency helps you understand what's being built.

Question 3

Can multiple messages be sent while working in Agent mode?

Accepted Answer

No, Agent mode processes one request at a time. Wait for the current request to complete before sending a new prompt.

Question 4

Does Lovable modify my project directly when in Agent mode?

Accepted Answer

Yes, Agent mode implements and verifies changes directly in your project. It thinks, plans, and takes autonomous actions to build features end-to-end. Use Plan mode first if you want to reason through changes before execution.

Question 5

How do I stop a request, and what happens when I do?

Accepted Answer

You can stop an in-progress Agent mode request by clicking Stop. Any changes made up until that point are saved, and you can revise or continue from there.

Question 6

Review knowledge periodically

Accepted Answer

Review your project and workspace knowledge every few months or after major changes. If Lovable is making decisions you don't like, check if your knowledge is outdated or unclear. Update it to reflect current preferences, new standards, or lessons learned. Think of knowledge as living documentation that evolves with your project.

Question 7

What happens if errors occur during implementation?

Accepted Answer

Lovable detects errors during implementation and uses the free 'Try to fix' button to auto-repair issues (~60% success rate for simple glitches). Use the Cloud → Logs tab to debug complex issues, or revert and re-prompt with a clearer description.

Question 8

Can I compare what changed between versions?

Accepted Answer

Yes, you can preview older versions and see what the AI modified. Use version history to inspect changes before reverting. If using GitHub integration, you can view detailed diffs between commits.

Question 9

How do I prevent the AI from breaking existing features?

Accepted Answer

Be specific in your prompts about what should and shouldn't change. Use phrases like 'Only modify the contact form—leave everything else unchanged.' Build incrementally with focused prompts rather than large, multi-part requests.

Question 10

My mobile layout got messed up when I edited the desktop version.

Accepted Answer

Revert to the last version where both layouts worked. When prompting, be specific: 'Update the desktop header only—don't change the mobile layout.' Breaking complex changes into smaller, targeted prompts helps the AI avoid unintended side effects.

Question 11

The AI broke something that was working fine. What do I do?

Accepted Answer

Use the version history to revert to a previous working version—nothing is lost permanently. All changes stay in chat and can be reapplied anytime. For future prompts, try specifying 'Don't change X' to protect existing functionality.

Question 12

Does chat / chat mode use credits

Accepted Answer

Plan mode (the conversational planning mode) costs just 1 credit per message since it's for reasoning and investigating ideas before code is written. Agent mode, which actually modifies code, uses variable credits depending on complexity. You can switch between them anytime.

Question 13

Where is Chat mode?

Accepted Answer

Chat mode was renamed to Plan mode in recent updates. If you're looking for the conversational, non-code-changing mode, that's Plan mode now. Plan mode costs 1 credit per message and lets Lovable explore ideas and reason about changes without modifying code. Use it for planning, investigation, and debugging.

Question 14

I lost credits because the AI produced an error. Can I get them back?

Accepted Answer

Credits are consumed when prompts are processed, even if the result isn't what you expected. If the error was caused by a Lovable system issue (not your prompt), contact support with details—we may credit your account.

Question 15

The AI used credits but nothing changed in my project.

Accepted Answer

Sometimes the AI processes a prompt but determines no changes are needed, or the changes are very small. Check the chat for the AI's response explaining what happened. If this seems like a bug, contact support.

Question 16

[Error Loops & Bugs] Does Lovable waste credits on failed bug fixes?

Accepted Answer

Using 'Try to fix' is FREE and never wastes credits—it scans logs, detects issues, and attempts quick fixes without consuming your plan's credits. Agent mode prompts do consume credits. Plan mode costs only 1 credit per message. Use 'Try to fix' liberally, and Plan mode to investigate before spending Agent mode credits.

Question 17

[Error Loops & Bugs] How to fix error loops / AI going in circles?

Accepted Answer

Break the loop by: 1) Click 'Try to fix' (free button that scans logs and fixes ~60% of simple issues), 2) Use Plan mode to investigate the problem before Agent mode tries again, 3) Revert to a stable version and re-prompt with clearer instructions, 4) Check Cloud → Logs for specific errors. Divide complex changes into smaller prompts.

Question 18

[Error Loops & Bugs] What to do when Lovable breaks your entire site?

Accepted Answer

Don't panic—use version history to revert: scroll up in chat, press 'View History', select an older stable version and restore it. Restoring creates a new edit card; nothing gets lost. You can reapply changes after reverting. Alternatively, click 'Try to fix' (free), or use Plan mode to carefully investigate before Agent mode tries again.

Question 19

Every prompt I send results in an error. The editor is unusable.

Accepted Answer

Try refreshing the page, clearing browser cache, and switching browsers. If errors persist only on one project, it may have a corrupted state—contact support with your project URL and error details. Check status.lovable.dev for any service-wide issues.

Question 20

The editor worked yesterday but now everything errors.

Accepted Answer

This is likely a temporary service issue. Check status.lovable.dev first. Try again in 30 minutes. If it's project-specific, try opening a different project to confirm. Contact support if the issue lasts more than an hour.
