LabGen

LabGen analyzes an uploaded picture and writes a structured prompt you can reuse in models like Nano Banana, Flux or Seedream. It also stores, tags and reuses prompts, and can generate and edit images itself, which makes it useful for creators who collect visual references.

For image-to-prompt you upload a file or paste a URL, then choose output language, prompt length and a focus point before generating. A Chrome extension captures prompts and images from other websites and sends them into the prompt manager, where they can be sorted into categories and reused later.

Text-to-image and image-to-image generation run inside the same workspace, so a saved prompt can go straight into a new render. Paid plans are credit-based and include premium models, unlimited prompt storage and permanent storage of your creations.
