Feature Comparison

NB2 Hub

Faithful Text & Image Remix

Upload a reference image and a short prompt, and NB2 Hub will intelligently remix it while meticulously preserving the original layout, composition, and lighting. This feature is built for rapid iteration, allowing you to upgrade textures, enhance details, or change stylistic elements without starting from scratch. It's perfect for refining product shots, iterating on UI designs, or creating consistent comic panels with incredible speed and fidelity.

Crisp On-Image Text Generation

Generate images with clean, legible, and perfectly integrated text directly inside the visual. NB2 Hub's Nano Banana Pro engine understands typography and layout, producing headlines, paragraphs, and multilingual text without blurry edges or visual artifacts. This eliminates the need for separate text overlays in editing software, making it a fast and efficient solution for creating posters, social media covers, and advertisement graphics ready for immediate use.

Multi-Reference Fusion & Identity Consistency

Fuse elements from multiple reference images into a single, cohesive new creation while maintaining strict consistency for characters, products, or brand elements. This powerful feature enables the rapid creation of storyboards, multi-angle product sets, and surreal composite images. It ensures your subject's identity remains locked and accurate across all generated shots, streamlining workflows for campaigns and visual storytelling.

Pro-Level Lighting & Camera Control

Exercise precise creative control over the final image with advanced settings for lens type, framing, depth of field, and color grading. Perform local edits and dramatic mood shifts like changing a scene from day to night. This gives you on-demand cinematic quality and specific dramatic effects, such as chiaroscuro lighting, allowing for professional-grade artistic adjustments with simple prompt-based commands.
