NB2 Hub — Overview
NB2 Hub is a browser-based interface for Nano Banana-style image generation, providing both text-to-image and image-to-image workflows. It emphasizes reproducible, instruction-following outputs (strong character consistency, pixel-level instructions) and fast high-resolution results.
Key technical features
- Text-to-image and image-to-image generation with support for flexible aspect ratios and high-resolution exports (4K-capable claims).
- Multi-step internal pipeline: planning, drafting, analysis and refinement to improve instruction following and consistency across edits.
- Precise spatial reasoning: shows examples like accurate clock hands (11:15) and filling a wine glass to the brim.
- Strong text and UI rendering: near-realistic UI screenshots and readable typography for mockups and dashboard restyling (including light-to-dark transformations).
- Faithful remasters and structural edits: preserve original composition while upgrading visual fidelity (game assets, retro images, manga colorization and translation).
- Fast turnaround: advertised sub-10-second generation for high-resolution images.
Practical use cases
- Game developers and remaster teams upgrading legacy assets to modern high-resolution visuals.
- UI/UX designers creating realistic mockups or switching themes (e.g., dark mode) while preserving layout and readable text.
- Digital artists and illustrators performing instruction-driven edits and faithful remasters.
- Content creators generating social media thumbnails, marketing assets, and multilingual mockups.
- Translators and manga editors colorizing pages and replacing text while maintaining panel layouts.
- Educators generating accurate whiteboard math and step-by-step diagrams for instructional materials.

Designers, artists, game developers, product teams, marketing professionals, and power users who need precise, repeatable image edits and high-quality generations.
