Image Describer is a web-based AI tool that analyzes an uploaded image and writes text about it. Outputs include short and detailed descriptions, alt text, SEO-friendly text, object recognition, style analysis, text extraction (OCR), and prompts for Midjourney, Flux, Stable Diffusion or general use. Visitors can try one analysis without logging in, and the site operates under the name ImageDescriber.
The product targets people who need written versions of visuals: site owners handling accessibility and SEO, marketers producing captions, and creators who reuse reference images as prompts. The homepage also lists a PTE Describe Image practice tool for English learners. Its own FAQ warns that AI output can miss details, so results should be checked against the original image.
The workflow has three steps. You upload an image or paste an image URL, with JPG, PNG, WebP and HEIC supported. You then choose the analysis options, such as a detailed description, alt text or SEO content, and an output language. The AI analyzes the image and returns ready-to-use text in seconds.
Results can be copied or downloaded. Recent results are saved only in your browser for up to 7 days and up to 20 records, and are not synced to any cloud history. Temporary server uploads are removed after processing. Each selected output type costs 1 credit per image, and credits are deducted only after the model output finishes.
The core feature is the range of outputs from one upload. Besides short and detailed descriptions, the tool offers alt text, SEO-friendly text, object recognition, style analysis and OCR. Prompt outputs are available for Midjourney, Flux and Stable Diffusion, turning subject, lighting, color and composition into a structured prompt. Paid accounts can select several outputs for one image.
For volume work, the batch tool takes up to 100 images of up to 20 MB each, with a 200 MB total, and exports completed results as CSV, TXT or JSON. The site also describes social captions with hashtags and an API with key authentication. It does not include ZIP packaging, webhooks or an official SDK.
