Features of NB2 Hub

Faithful Text & Image Remix

Upload a reference image and a short prompt; the AI preserves the original layout, composition, and lighting while intelligently upgrading details, textures, and style. This is ideal for iterating on UI designs, enhancing product photography, or remastering comic panels without losing the foundational structure.

Crisp On-Image Text Generation

Generate images with clean, fully legible text rendered directly inside them. The model handles multilingual typography for headlines and paragraphs without common artifacts like blurring or halos. This feature is perfect for creating posters, advertisement creatives, and social media covers that require integrated copy.

Multi-Reference Fusion & Identity Lock

Fuse elements from multiple uploaded reference images into a single, cohesive output. Crucially, it maintains strict consistency for characters, products, and brand elements across different shots. This enables the creation of consistent storyboards, multi-angle product sets, and branded content series.

Pro Lighting & Camera Control

Exercise fine-grained creative control over the final image's aesthetic. Adjust virtual camera settings like lens type, framing, and depth of field. Perform local edits and dramatic mood shifts like changing a scene from day to night. This allows for achieving specific, cinematic visual effects on demand.
