Altify AI is an auto ALT text and AI ALT text plugin for WordPress images. It helps generate descriptive image ALT text for accessibility and image SEO.

Use bulk image ALT text tools for your Media Library, generate featured image ALT text automatically, and scale WooCommerce image ALT updates with AI or offline mode.

Key features:

Beginner-friendly Automation tab with upload toggle, daily schedule, and one-click Run scan now.
Automatic ALT generation on new image uploads with selectable mode priority (Offline first, AI first, Offline only, AI only).
Daily background scan for missing ALT (or all images) with mode selection, run limit, and status panel.
Top-level Altify AI admin menu (before Posts) with dedicated Settings and Generate History pages.
AI mode with OpenAI model settings, rate limiting, retry/backoff, and safe fallback behavior.
Offline mode (no API) that generates ALT from title/caption/description/filename.
Bulk Media Library processing with filters, batching, and pause/resume/stop controls.
WooCommerce bulk generation for featured and gallery images with category/date filters.
Generation history table with source, method (AI/Offline/Cache), ALT preview, and row-level delete controls. Settings page shows the latest 10 rows for quick review.
Multilingual support: Auto (site locale), many built-in languages, and custom language input.
Optional vision-based analysis for image-aware ALT suggestions.
Native WordPress ALT field updates (_wp_attachment_image_alt) for SEO plugin compatibility.
Smart protection for existing ALT text via Only fill empty ALT and Overwrite existing ALT.

SEO and accessibility benefits:

Improves image context for screen readers.
Reduces missing ALT text across large media libraries.
Keeps ALT text in the native WordPress field (_wp_attachment_image_alt) for compatibility with SEO plugins.
Avoids duplicate custom ALT fields and vendor lock-in.
Supports content quality workflows with configurable length and overwrite behavior.

How it works:

Plugin gathers safe text context from attachment metadata (filename, title, caption, description).
Optional product context is added for WooCommerce images (product name/category).
OpenAI returns a concise ALT suggestion.
Result is sanitized and stored in the standard WordPress ALT field.
If API fails (or offline mode is used), the plugin writes a clean metadata-based ALT text fallback.

External services

This plugin connects to the OpenAI API to generate ALT text suggestions for image attachments.
It is required for AI-based ALT text generation features (single upload automation, media bulk generation, and WooCommerce image bulk generation), unless Offline mode is enabled.

Service used:

OpenAI API (https://api.openai.com/v1/chat/completions)

Data sent and when:

Sent only when an admin-triggered or configured ALT generation request is executed.
Sent data includes metadata/context built from WordPress attachment fields:
- Attachment filename (cleaned)
- Attachment title/caption/description
- Optional WooCommerce product name/categories when available
- Generation settings such as requested language and max length
If Analyze actual image (Vision) is enabled, a resized image preview may also be sent.
If Offline mode is enabled, no OpenAI request is sent.

FAQ

Does this overwrite existing ALT text?

No, not by default. Only fill empty ALT is enabled by default and Overwrite existing ALT is disabled.

Is this plugin useful for SEO?

Yes. It helps maintain descriptive image ALT text, which improves image context for search engines and accessibility tools.

Where is ALT text stored?

In the standard WordPress attachment meta key _wp_attachment_image_alt, so it remains compatible with SEO plugins.

Which images are processed for auto ALT text?

Only new uploads are processed when Auto-generate ALT on media upload is enabled. You can turn this on/off in the Automation tab.

Can it scan my old images every day for missing ALT text?

Yes. Enable Daily scan for missing ALT in the Automation tab, choose time/scope/mode, and the plugin will process up to your daily max image limit.

Can I run the daily scan immediately?

Yes. Use Run scan now in the Automation tab to trigger the same scan logic instantly and refresh status counters.

Where can I find Generate History?

Go to Altify AI > Generate History in WP Admin. The Settings page also includes a quick history table showing the latest 10 rows.

Can I process only images with missing ALT text?

Yes. Bulk mode defaults to Only missing ALT, and you can switch to all images if needed.

Does this plugin support bulk image ALT text generation?

Yes. The Bulk Generator tab processes existing Media Library images in batches with pause/resume controls.

What happens if OpenAI API fails or rate limits?

The plugin retries with exponential backoff for temporary API errors and uses a clean metadata-based fallback ALT text if needed.

Can I generate ALT text without OpenAI?

Yes. Use the Offline Mode tab to run metadata-only generation with zero API calls.

Can AI analyze the actual image (not only filename/title)?

Yes, when Analyze actual image (Vision) is enabled in settings.
When disabled (default), generation is metadata-only (filename/title/caption/description).

Does the plugin upload image files to OpenAI?

By default, no.
If Analyze actual image (Vision) is enabled, the plugin sends a resized image preview to OpenAI for analysis.

Can it generate featured image ALT text automatically?

Yes. Upload automation covers regular WordPress images, including featured images when they are image attachments in your library.

Does it support WooCommerce image ALT updates?

Yes. It can process product featured images and gallery images when WooCommerce support is enabled.

Can I run this on multilingual sites?

Yes. Choose Auto (site locale), select from many built-in languages, or use Custom to enter any language name.

Can I control cost and API usage?

Yes. You can configure model, max tokens, temperature, batch size, and requests-per-minute limit.

Can I delete history rows?

Yes. History is shown in a table with Select all, Remove Selected, and Clear All actions.
