Mashuk GenCard — AI product-card studio

Mashuk Express sellers spend too much time building product cards: they need a clean-background photo, a tidy layout and a consistent style. Most have no designer, so card quality varies wildly — which hurts catalogue conversion and the marketplace's brand.

The goal: give every seller a tool that turns a plain product photo into a ready, on-brand marketplace card in under a minute, with no image editors involved.

We built a standalone service embedded in the Mashuk Express ecosystem. Login is by phone number and limited to verified sellers (checked against Mashuk's existing database; SMS confirmation lands in the next phase).

Inside the generation studio:

- Upload a product photo and an optional background, add a text description, and pick one of 4 templates: Minimal, Dynamic, Premium, Lifestyle.

- Generation runs on Gemini 3 Pro Image (Nano Banana Pro) via ZvenoAI's OpenAI-compatible API — the model takes photo references plus text and returns a finished card.

- Refine the result with a free-form prompt ("make the background lighter", "add a highlight") — edits are applied on top.

- Download the finished PNG in one click.

A seller assembles a clean, on-brand card in three steps — photo → template → generate — without a designer. The catalogue gets visually consistent cards, and the marketplace gets a controllable house style.

The service is designed as an independent module that can plug into the seller dashboard and scale across the whole marketplace. Next up: SMS login confirmation, a generation history, and storing cards in S3/CDN instead of returning base64.
