AI Image Describer
Upload a photo to AI Image Describer and get back text in one of five formats: a detailed description, SEO alt text, social caption, AI art prompt, or extracted OCR text. Drag in a JPG, PNG, or WebP file, pick your output type, and copy the result in about 3 seconds. No account is required to start.
Most image captioning tools focus on one output format. AI Image Describer bundles five modes on a single page, including alt text capped at 125 characters and a dedicated image-to-prompt generator for Midjourney, Stable Diffusion, and Flux. Uploaded files are processed in memory and never stored on the server.
It fits SEO teams writing alt text at scale, e-commerce sellers drafting product copy from photos, and accessibility reviewers checking WCAG compliance. The free tier covers daily descriptions with 1 MB uploads, while Pro plans raise the limit to 20 MB and add batch processing.
