Google's Generative AI Plugin Suggests Accessible Text Alternatives in Docs

AI · 3 min read

The plugin analyzes images and chart metadata to propose succinct, context-aware alt text and detailed long descriptions when needed. It includes prompts that ask the creator what information the visual is meant to convey and uses that to prioritize content in the generated description, aiming to align with WCAG authoring practices.

Google highlights privacy and review controls: suggested alt text is presented as recommendations that authors edit and approve rather than auto-published content. Organizations can also link the plugin to internal style guides to ensure brand and legal requirements are respected during generation.

Accessibility directors caution that AI-generated alt text is a starting point and not a substitute for people with lived experience validating content. However, pilot customers report the plugin reduces the time to produce accessible reports by as much as 60%, and it surfaces common omissions in training material that previously went unnoticed.
