Knows the brand. Reads the catalog and the website.

Brings in the store catalog, organizes it and understands what the brand is like.

Spots what to push. On real products.

A few concrete opportunities, backed by evidence.

Creates the content. True to the garment.

Images and copy ready to publish.

From your chat, with the catalog inside.

Connects the store. In one click.

OAuth with Shopify and Mercado Libre. Catalog, stock and sales sync daily.

Demos with sample data from a fictional brand, recreated from the app.

01 — The problem

At a small fashion brand, one person runs the catalog, Instagram, the store and the campaigns.

Information is scattered across the store, Meta, photos, stock and metrics. AI tools start at image generation, which is the end of the problem, not the beginning.

02 — What I built

From onboarding to the finished ad.

  • Onboarding that reads the website and builds the brand kit
  • OAuth integrations with daily sync
  • Opportunities on real products, with deterministic ordering
  • Commercial brief → concepts → image + copy
  • MCP server for Claude and ChatGPT

03 — Key decisions

AI proposes, the server verifies

Every recommendation cites evidence the server checks. Anything unsupported is dropped.

Simple signals before opaque models

Traceable, explainable opportunities until there's data on what works.

The image is not the product

Generating is a capability. The value is in deciding what to show.

04 — Where it stands

My own product, in validation, with the website and app in production.

I don't show traction or testimonials because I don't have them yet. When there are real results, they'll be here.
