"Bring-Your-Own-Key was the seller. I bring my own Claude key and pay ~$8/mo in tokens instead of $99 elsewhere. The arbitrage agent caught a $14 spread between Etsy and Shopify on day 2."
"Autopilot is a game-changer. I sleep, agents post, repricer adjusts. Woke up to 7 new orders my pricing-advisor agent re-tagged overnight. Setup took 12 minutes. Site Audit alone was worth the subscription."
