About the startup
Generate and edit AI images in the browser, with 1K–4K output, up to 14 reference images, character consistency, and conversational multi-turn editing. NanoBanana21 is a browser-based AI image studio built on Nano Banana 2.1, Google's high-efficiency model for image generation and conversational image editing. It combines generation and editing in one workspace: start from a text prompt, upload up to 14 reference images, or blend both to produce detailed visuals in 1K, 2K, or 4K. You can edit images conversationally across multiple turns, maintain character consistency for up to 4 characters and object fidelity for up to 10 objects, and render clearer in-image typography. Additional features include Google Web and Image Search grounding, adjustable thinking levels, prompt optimization, and flexible quality and aspect-ratio settings. A free tier lets you start generating directly in your browser.
