Visual Prompt created by SocialTech

At a Glance

Prompta Visual is designed as a full-stack AI creative platform that enables brands to produce product and advertising visuals in line with their visual identity. The platform combines brand analysis, single and bulk image generation, ready-made creative templates, production history, credit management, and user settings into a single workspace. The goal was to accelerate the creative preparation process for various platforms while centrally managing brand consistency and production costs.

The Challenge

The system should not be merely a simple tool that generates visuals from text. Each brand’s tone, target audience, color palette, visual style, and prohibited expressions needed to be integrated into the production process; consistent creatives suitable for different platform dimensions had to be generated from a single product image. At the same time, batch productions needed to be reliably queued, costs controlled, failed processes managed, and user accounts kept secure.

What We Did

The application was developed with a React and Vite-based responsive client and a NestJS-based API layer. The Brand DNA module analyzes data collected from the brand website, professional Instagram account, and manual inputs using Gemini, transforming it into an editable brand profile. This profile is automatically incorporated into the prompt generation process along with template and platform preferences.
On the image generation side, single or CSV-based batch production workflows were created using the OpenAI Image API. While operations run in the background via Redis and BullMQ, job polling, cancellation, partial success, retry, and model fallback scenarios are supported. The generated files were stored on Supabase Storage; production history, assets, user settings, and credit transactions were logged using Prisma and PostgreSQL.
On the security side, server-side Supabase Auth, HttpOnly JWT cookies, refresh token verification, and TOTP-based 2FA were used. The credit system was designed to reserve estimated credits before production, collect payments for successful productions, and automatically refund unused credits.

Result

The result is a comprehensive AI creative workspace that takes brands’ visual identities from analysis to production. Users can process product images individually or in bulk, create variations for different social media and ad formats, utilize ready-made templates, and track the entire production history from a single point.
Prompta Visual offers a scalable infrastructure that reduces manual creative preparation time, makes high-volume production manageable, and ensures brand consistency across every visual.
