Generate accurate, SEO-optimised alt text for every image automatically

MarketingDocumentsAnalyticsEcommerceAIAutomationWebsite & CMS

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.

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.

What your agent runs for you

  • Sales
    15 min / week
    Manual 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.

    Agent generates alt text for every outbound asset

    When 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.

  • Marketing
    45 min / week
    Manual 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.

    Agent generates and writes alt text at publish time

    When 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 Support
    20 min / week
    Help 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.

    Agent generates alt text for every help article image

    When 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 Resources
    10 min / week
    Onboarding 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 Agent

    Agent ensures every HR document image has alt text before distribution

    When 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.

  • Finance
    8 min / week
    Chart 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 Agent

    Agent generates alt text for all financial visuals pre-distribution

    Before 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.

  • Operations
    60 min / week
    Accessibility 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.

    Agent runs weekly page scans and clears gaps proactively

    Every 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.

  • Legal
    30 min / week
    ADA 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.

    Agent produces documented compliance evidence before every launch

    Before 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.

FAQs

Questions about AltText.ai + Actionist

How does Actionist connect to AltText.ai?
Go to the Apps tab, find AltText.ai, and click Connect. The only connection method is an API key — generate one from your AltText.ai account under Account → API Keys, give it a label like 'Actionist', and optionally set a per-billing-cycle credit limit. Paste the key into Actionist and click Test connection. Actionist makes a read-only call to your account to confirm the handshake before any generation actions run.
Does AltText.ai charge per image generated through Actionist?
Yes — AltText.ai operates on a credit model, and each image generated consumes one credit regardless of whether it is triggered through Actionist, a native plugin, or the web interface. Credits are shared across all API keys on your account. To prevent unexpected depletion, you can set a credit limit on the specific API key you create for Actionist from within your AltText.ai account settings. The Get Account Info action lets your agent check remaining credits before submitting large bulk jobs.
Can the agent generate alt text in multiple languages at once?
Yes — AltText.ai supports 130+ languages and the Generate Alt Text in Multiple Languages action lets you pass a comma-separated list of language codes in a single API call. The response contains all requested descriptions simultaneously. For images already in your library, the Add Translation to Existing Image action adds a new language without regenerating any existing descriptions. Both actions are useful for multilingual CMS workflows where locale-specific alt text fields need to be populated independently.
What CMS and e-commerce platforms does AltText.ai work with through Actionist?
Through Actionist's API connection, the agent can generate alt text for images in any platform that exposes image URLs — including WordPress, Shopify, WooCommerce, Contentful, Storyblok, DatoCMS, Cloudinary, BigCommerce, Magento, and Ecwid. AltText.ai also has native plugins for WordPress, Contentful, and Shopify if you prefer a direct integration alongside Actionist for different workflows. The Actionist connection is most valuable for platforms where a native plugin does not exist, or for cross-platform workflows that span multiple content systems.
Can the agent incorporate SEO keywords into the generated alt text?
Yes — the Generate Alt Text with SEO Keywords action accepts a keyword list alongside the image URL. AltText.ai weaves the keywords naturally into the description rather than appending them mechanically, so the output reads as genuine accessibility copy that also reinforces search relevance. For WordPress users with Yoast, RankMath, or SEOPress installed, the focus keyword can be pulled from the post's SEO settings and passed to AltText.ai automatically, producing descriptions that align with the page's target search term without any manual input.
How does bulk processing work, and how does the agent know when it is done?
Bulk generation via the Bulk Generate Alt Text from CSV action is asynchronous — you submit a CSV of image URLs with optional keyword and language columns, and AltText.ai processes them in the background. The agent can poll Get Generation Status to track progress, or you can configure AltText.ai webhooks to notify Actionist when processing completes. For large catalogues (hundreds or thousands of images), the bulk approach is significantly faster than sequential single-image calls and does not hold up the agent while waiting for each image to process.
Can I use a custom AI prompt to control how the alt text is written?
Yes — the Generate Alt Text with Custom Prompt action lets you override AltText.ai's default prompt to control tone, format, detail level, and terminology. This is valuable for e-commerce product photography (include material names, dimensions, colourways), technical diagrams (describe components and data flow rather than visual appearance), medical or legal imagery (use clinical or regulatory language), or luxury brands (apply brand voice guidelines). The custom prompt can include the {{AltText}} macro to post-process a generated description with a second instruction, such as 'shorten to under 120 characters'.
Does using AltText.ai through Actionist help with ADA and WCAG compliance documentation?
Actionist can make ADA/WCAG compliance more systematic — the Scan Web Page for Missing Alt Text action audits any public URL and returns a list of images without descriptions, and the subsequent generation actions fill every gap. Combined with logging to Google Sheets or Notion, the agent builds an audit trail showing which pages were scanned, when, and what alt text was generated or already present. This does not constitute legal compliance certification, but it provides the documented evidence of accessibility effort that many compliance frameworks and legal teams require.
