# Free tools for your builder marketing work

AgAI Labs offers three free browser tools for custom builders: a UTM link builder, a lead-source log and a proof kit self-check. Each one runs in your browser with your own channels and records. The tools send nothing to AgAI Labs. Use them before a campaign goes out, while inquiries come in and when you review your site.
