Product Launch Hero
Everything you need for consistent banners
Phase 1 ships the core generation pipeline. Editor and admin land in the next milestones.
Prompt-based generation
Type what you want, optionally drop in a reference image. No design tools, no templates to wrestle with.
Multi-model pipeline
Every prompt fans out to several state-of-the-art models — SDXL, Imagen, Flux, and more — running in parallel.
Automated scoring
An AI evaluator scores every output for composition, clarity, and on-brief accuracy. Only ≥ 80 are surfaced.
Best-output selection
Nanogen picks the winning banner automatically. Runners-up stay one click away when you want to compare.
Dark-first interface
Designed for long sessions. Crisp typography, calm contrast, and a one-click theme toggle when you need it.
Built to scale
Asynchronous model execution, efficient image processing, and storage for every asset you generate.
