What they did

A founder had Grok Bot scan Gmail invoices for subscriptions it could rebuild. It built an AI-visibility bot to replace a $399/mo SEO tool; with lots of feedback it reached about 80% of the quality for about $45/mo.

How it went

Single founder report with the exact prompt; author says first versions were about 10% as good and it took a lot of human feedback to reach ~80% at 1/10th the cost ($45 vs $399). Your results will vary

Prompt

Original prompt, as posted by the author.

Check my invoices in Gmail. If there are any subscriptions you think you could compete with, design and launch a bot team to compete with it based on its 1-2 core features and price. Feed the results to a separate eval bot with a blinded test to prevent bias. Use any tools or plugins needed, and report back to me if any are fruitful. Don't cancel anything yourself.
