About Labgen
LabGen is an AI creation and prompt management platform built around an Image to Prompt generator. Users upload or paste an image (JPG, PNG, WebP, HEIC and other formats, up to 5MB) and the tool analyzes subject, composition, color, lighting and style to produce a ready-to-use prompt. Output can be tuned by target model (such as Midjourney, Flux, Seedream, Nano Banana, ChatGPT or Gemini), target language, focus point and word count, and it can also produce marketing copy, short stories or structured JSON prompts.
Extracted prompts can be saved to a prompt library with categories, tags and private visibility. A Chrome extension collects prompts from any website and lets users copy saved prompts into other AI tools. The platform also includes text-to-image, image-to-image, an image extender and utilities like a background remover, image compressor and grid splitter.
The standard mode is free and needs no login. The site describes use by AI art creators, content creators, SEO specialists writing alt text, accessibility designers, teachers and product managers.
