Most solopreneurs and small agencies leave the single easiest revenue lift on the table: the checkout order bump. Their checkout has one product and one button, so every buyer spends exactly what they intended and not a dollar more. The real blocker isn't laziness — it's that nobody knows WHAT to offer at checkout or how to word it. A bump has to be complementary, cheap enough to be an impulse yes, and phrased in one tempting line that doesn't scare the buyer off the page. Faced with a blank 'order bump offer' field, most sellers skip it entirely or paste a lazy 'add a bonus for $17' nobody clicks — quietly bleeding profit on every order they were already going to make.

Ruthless specificity: it only does order bumps. Paste any offer and get five complementary bumps — each with a headline, one-line pitch, checkbox-ready microcopy, and an impulse price — formatted to paste straight into SamCart, ThriveCart, or any funnel builder's bump slot. Not a general copywriter; a specialist that optimizes the one checkout field that prints money.

P2 — buyer supplies their own API key. source/.env.example lists ANTHROPIC_API_KEY (or OPENAI_API_KEY) marked 'REQUIRED — app does not run without this'. The main API route surfaces a 'Set API key in .env' message at boot when the key is unset — no silent fallback to demo. A seed/examples.json ships for reference only.
