AltText.ai
· #311 most-usedGenerate accurate, SEO-optimised alt text for every image automatically
AltText.ai uses AI computer vision — powered by GPT-4 Vision and Claude — to automatically write descriptive alt text for images at scale. It connects to your CMS, e-commerce platform, or custom workflow via a REST API, native plugins, or an MCP server, and writes accessibility-compliant descriptions in 130+ languages in seconds. Connect it to Actionist and your agents can generate alt text on new image uploads, audit pages for missing descriptions, translate alt text into additional languages, and manage your full image library — all without manual copywriting.
Eliminates manual work. Agents eliminate the manual cycle of opening images, writing alt text one-by-one, translating descriptions, and auditing CMS pages for missing accessibility copy.
What your AltText.ai agent runs on autopilot
A week of scheduled jobs your Actionist agent will execute on your behalf.
AltText.ai × every other app you use
End-to-end automations that span multiple apps — each one a real business outcome.
New CMS image auto-gets alt text before publish
When a content editor uploads a new image to the CMS, the agent calls Generate Alt Text with the page's focus keyword included, waits for the result, and writes the description back to the image's alt text field — all before the editor sees the upload dialogue close. No image goes live without a description, and no editor has to write one manually.
Time saved for your team — every week, on autopilot

What your team gets back — two angles: what you stop doing manually, and what that's worth.
What you do manually today
What your agent runs for you
- Sales15 min / weekManual alt text on sales assets
Sales reps add alt text to proposal images and deck visuals by hand — or skip it entirely, sending inaccessible materials to prospects using screen readers.
Sales Agent0 minAgent generates alt text for every outbound assetWhen a proposal or case study image is added to the asset library, the agent generates accurate alt text automatically — every prospect receives accessible materials without any rep action.
- Marketing45 min / weekManual alt text on every campaign image
Marketers write alt text for each campaign image by hand before publishing — a time-consuming step often skipped under deadline pressure, leaving pages with blank alt attributes.
Marketing Agent0 minAgent generates and writes alt text at publish timeWhen a new image is uploaded to the CMS, the agent calls AltText.ai and writes the result to the alt field before the page is published — zero manual intervention and no missed images.
- Customer Support20 min / weekHelp article screenshots lack alt text
Support writers rarely add alt text to knowledge base screenshots, leaving visually impaired customers without context when they rely on screen readers to navigate help content.
Customer Support Agent0 minAgent generates alt text for every help article imageWhen a new help article is published, the agent scans it for images, generates alt text for each screenshot via AltText.ai, and writes the descriptions back to the article — the knowledge base is fully accessible from the moment it goes live.
- Human Resources10 min / weekOnboarding documents distributed without accessible images
HR uploads handbooks and onboarding guides to Google Drive without adding alt text to diagrams and screenshots — employees using assistive technology cannot access the visual content.
Human Resources Agent0 minAgent ensures every HR document image has alt text before distributionWhen a new document version is uploaded, the agent extracts images, generates alt text via AltText.ai, and updates the document before it is shared with new hires — accessibility is built in, not bolted on.
- Finance8 min / weekChart images in board decks have no alt text
Finance teams embed chart screenshots in board decks and investor documents without alt text — any board member or stakeholder using assistive technology cannot interpret the visuals.
Finance Agent0 minAgent generates alt text for all financial visuals pre-distributionBefore a board deck or investor report is distributed, the agent sends each embedded chart image to AltText.ai and inserts the generated descriptions — every financial document is screen-reader accessible from the first distribution.
- Operations60 min / weekAccessibility gaps discovered in external audits
Without scheduled audits, missing alt text on web pages is only discovered when an external accessibility audit or legal complaint forces a reactive remediation sprint.
Operations Agent0 minAgent runs weekly page scans and clears gaps proactivelyEvery Monday, the agent scans the top pages through AltText.ai, generates alt text for any missing images, and logs coverage metrics — accessibility is maintained continuously, not patched reactively.
- Legal30 min / weekADA compliance relies on manual periodic reviews
Legal commissioning an accessibility audit every quarter means accessibility gaps accumulate for months before being addressed — exposing the business to complaint or litigation risk.
Legal Agent0 minAgent produces documented compliance evidence before every launchBefore each web property launch, the agent scans all pages, fills gaps via AltText.ai, and writes a coverage report to the compliance log — providing documented WCAG evidence on demand rather than per quarter.
