Vision AI looks at your image and writes what it sees in clear, natural language — the main subjects, the scene, the style and colours, the mood, and any text it can read. It's a fast way to produce accessible alt text, draft captions, or simply understand an image you can't quite describe yourself.

What you can do with it
Accessibility (alt text)
Generate descriptive alt text for images so screen-reader users — and search engines — understand your visuals. Better alt text is one of the strongest, most overlooked SEO and accessibility wins.
Captions & social
Turn a photo into a ready-to-edit caption for social posts, product pages, or a photo journal — then tweak the tone to match your voice.
Cataloguing & search
Describe large image libraries to make them searchable: products, real-estate photos, stock archives, or research datasets become text you can index and query.
Understanding & study
Get a second pair of eyes on a chart, diagram, artwork, or screenshot — useful when you need to read fine detail or extract on-image text.
Frequently asked questions
- How accurate are the descriptions?
- The model is a state-of-the-art vision system and is highly accurate for everyday photos, products, scenes, and on-image text. As with any AI, review the output before publishing — especially for nuanced or safety-critical content.
- Can it read text inside the image?
- Yes. The describer extracts and reports legible text it finds in the image (signs, labels, captions, UI), which is handy for screenshots, documents, and product shots.
- What image formats and sizes are supported?
- Upload JPEG, PNG, or WebP up to 10 MB. The image is processed securely and used only to generate your description.
- Is this good for alt text?
- It's one of the best uses. Paste the generated description into your image's alt attribute (trimming to the essentials) to improve accessibility for screen-reader users and give search engines a strong content signal.
