THE PROBLEM

The angle
Not 'AI-powered forecasting' — that's generic. The real angle: ops directors are still forecasting inventory in spreadsheets across dozens of stores, and every stockout or overstock is a manual-process problem, not a strategy problem.
| Stop forecasting inventory in spreadsheets | Direct, problem-first |
| Your ops team is doing math a machine should do | Provocative |
| 15-20% less overstock, without adding headcount | Numbers-led |
Still forecasting inventory across stores in a spreadsheet? See what it looks like automated — 15-20% less overstock, no new headcount. 20-minute demo, no pitch deck.
WHAT IS MARKETING COPYWRITER AGENT?
An AI marketing copywriter agent turns a product, audience and campaign goal into a matched set of copy — headline options, a short ad, and a landing-page intro — all built around one specific, honest angle instead of generic feature-benefit language repeated across formats.
HOW IT WORKS
The agent is prompted to find one specific angle before writing anything — a real, checkable detail about the audience's actual situation (they're forecasting in spreadsheets, not 'they need efficiency') — because copy built on a generic benefit reads like every other SaaS ad and gets ignored the same way a generic cold email does. Every subsequent piece (headlines, ad, landing intro) is required to pull the same thread as that angle, so the campaign feels like one coherent argument instead of three unrelated pieces of copy glued together.
This mirrors the specificity rule used across the outreach agents on this site: personalised, concrete copy consistently outperforms generic copy, which is the same principle behind the 21.8% reply rate on personalised production outreach.
You are a direct-response copywriter for a B2B SaaS marketing team. Given a product, audience and campaign goal, find one specific angle (not generic benefits), then produce: 3 headline options, one short ad (under 40 words), and a landing-page intro paragraph — all consistent with the same angle. Output ONLY a JSON array of typed blocks matching the OutputBlock union — no prose outside the JSON. The angle must come from what the input actually describes about the product and audience — never invent a customer detail, statistic, or claim the input didn't supply.USE CASES

FAQ
Common questions
How does this avoid generic 'AI-sounding' marketing copy?
It's prompted to find one specific, checkable angle about the audience's real situation before writing anything, and every piece of copy is required to pull that same thread instead of restating generic benefits.
What formats does it write?
Headline options, a short ad, and a landing-page intro paragraph in one pass — all consistent with the same angle, so they work together as one campaign.
Does it replace a copywriter?
It replaces the blank-page first draft. A copywriter or founder still refines tone, brand voice and final polish — the agent removes the slowest part of getting started.
