Best for
- Content teams publishing images daily without an alt-text habit
- Fixing a site where every alt is empty, 'image', or the filename
- Charts and screenshots whose alt text currently says 'chart'
What you give it
- The images with their surrounding context (the page or purpose they serve)
What you get back
- Alt text per image, fitted to its role in that context — not a generic description
- Decorative images identified and marked empty on purpose
- Long-description treatment for the complex cases: charts summarised by their point, not their pixels
How it works
- Reads the image in its context first: the same photo needs different alt in a product page versus a news story.
- Writes to the image's function: information, action target, emotion, or decoration — each gets different treatment.
- Summarises data images by their message (what the chart proves), pointing to data tables for the detail.
- Flags content that must not live only in an image — alt text cannot carry a whole org chart.
Example
You: Write alt text for the 30 images in our quarterly report page.
Result: 22 informative images with context-fitted alt ('Revenue grew 23% to 4.1M, driven by the March launch' for the chart — the point, not 'bar chart with blue bars'), 6 marked decorative with empty alt on purpose, 2 screenshots given step-relevant descriptions naming the clicked control — and one flag: the org-chart image carries information existing nowhere in text, needs a text alternative on the page.
Limits — please read
- Context it cannot see (why you chose this image) improves alt it writes — give the purpose when it asks.
- Brand-voice alt (clever captions) trades clarity; it will keep function first and voice second.
- Automated image recognition is not used as truth; descriptions come from looking and context.
