Features of NB2 Hub

Faithful Text & Image Remix

Upload a reference image, drop a short, spicy prompt, and watch the magic happen. NB2 Hub doesn't just slap on a filter; it deeply understands your original layout and lighting, then upgrades the details and texture with surgical precision. It's the ultimate tool for iterating on UI designs, leveling up product shots, or refining comic panels without losing the core composition. Think of it as a creative partner that gets your vision and executes flawlessly.

Crisp, Legible On-Image Text

Finally, an AI that can spell! Generate images with clean, razor-sharp text embedded right inside—from bold headlines to full paragraphs, in multiple languages. No more blurry, halo-ridden lettering that looks like a glitch. This feature is a total cheat code for creating posters, ad creatives, social media covers, and any asset where the words need to pop as hard as the visuals. Professional typography, on demand.

Multi-Reference Fusion & Identity Lock

Fuse multiple reference images into one cohesive masterpiece while keeping specific elements—like a character's face, a product design, or a logo—perfectly consistent. This is next-level control for building storyboards, creating multi-angle product sets, or crafting scenes that blend different visual elements. It’s like having a digital cloning lab for your creative assets, ensuring your brand and characters are unmistakable across every shot.

Pro Lighting & Cinematic Control

Take directorial command over your scenes. Fine-tune the lens, framing, depth of field, and color grade with intuitive controls. Want to change a sunny day to a moody night? Need a dramatic chiaroscuro effect with harsh, directional light? NB2 Hub lets you perform local edits and lighting shifts that used to require hours in Photoshop. Get cinematic, pro-level results with just a few clicks.

Frequently Asked Questions

Is NB2 Hub really free to use?

Absolutely. You can sign up and start generating 4K quality images for free right now. The platform operates on a credit system, and new users get free credits to kick the tires and see what the tech can do. For heavy-duty production work, there's a Pro tier that unlocks more credits and faster generation times.

What does "character consistency" actually mean?

It means the AI can remember and replicate specific subjects—like a person's face, an animal, or a product design—across multiple different images. If you generate a portrait of "Zara the cyberpunk detective," you can then ask for "Zara drinking coffee" or "Zara in a raincoat," and she'll maintain her core facial features, hairstyle, and defining characteristics. It's the holy grail for serialized content.

What kind of images can I upload for the image-to-image feature?

You can upload pretty much any standard image file (JPG, PNG, etc.). It works best with clear, well-composed reference photos. Use it to remix your own artwork, tweak product photography, or use a screenshot as a layout template for something entirely new. The AI uses it as a strong visual guide for structure and style.

How fast is the image generation?

It's blazing fast. Generations typically take around 40 seconds, depending on complexity and server load. The Gemini 2.5 Flash model is optimized for speed without sacrificing quality, making it practical for real-time ideation and iteration. You're not waiting around for your creativity to buffer.
