Alt text for every
WordPress image.
Written by AI.
AI Alt Text Generator Lite writes descriptive, SEO-friendly alt text for your WordPress media library — one image at a time or your whole library in bulk, handled safely by a robust processing queue. Bring your own AI key. No subscriptions, no limits.
Everything you need for
perfect image SEO
Built for site owners who care about accessibility, rankings, and saving hours of manual work.
Generate On Demand
Pick any image and generate its alt text with a single click — or queue a selection. You decide exactly what gets processed and when.
Bulk Generation
One click queues your entire existing media library — even thousands of images — and processes them safely in batches.
Bring Your Own AI
Use your own API key from Gemini, OpenAI, Claude, Azure, OpenRouter, Ollama or any custom endpoint. You stay in control.
Local AI Support
Run vision models on your own server with Ollama — completely free, private, and offline. No API key required.
SEO Boost
Descriptive alt text helps Google understand your images, improving image search rankings and overall SEO.
Accessibility First
Screen readers rely on alt text. Make your site WCAG-compliant and usable for everyone — one bulk run covers your whole library.
Smart Queue & Logs
A robust job queue with retry logic, plus full activity logs so you always know what was generated, when, and by which model.
Enterprise-Grade Code
Modern PHP 8.3 architecture, nonce-protected forms, prepared SQL statements, and clean uninstall — no leftovers.
One plugin. Multiple AI brains.
Pick your favorite provider, paste your API key, and you're done. Switch anytime without losing data.
From install to done —
on your schedule
Install & Connect
Upload the plugin, open Settings, choose your AI provider and paste your API key. The built-in connection test confirms everything works.
One Click or Bulk Queue
Generate alt text for any single image with one click, or hit "Bulk Generate" to queue your entire library. The queue processes batches safely in the background.
Relax — It's Done
Alt text is saved directly to each image in the media library. Track progress in the queue and logs as your site becomes more accessible and more discoverable.
Small attribute. Big impact.
Rank in Google Images
Alt text is how search engines "see" your images. Good descriptions mean more organic traffic from image search.
Meet WCAG Standards
Missing alt text is the #1 accessibility failure on the web. Screen readers depend on it — and so do your visitors.
Save Hours of Work
Writing alt text for hundreds of images by hand takes days. The plugin does it in minutes — while you focus on content.
Fallback When Images Fail
If an image can't load, alt text is what your visitors see instead. Make every pixel count.

No. Generation happens in the background through a robust queue system and scheduled processing — never blocking page loads for your visitors.
Absolutely. Every generated description is visible in the Images page where you can edit it, and you can regenerate any image's alt text with one click from the Logs page.
