Alt Text on
Autopilot.
AltVault generates SEO-friendly alt text for every image in your WordPress media library. Use the built-in browser AI for zero cost — or connect your own Anthropic or OpenAI key for higher accuracy. Your choice, one plugin.
How It Works
Three simple steps to SEO-friendly alt text for your entire media library.
Scan
AltVault scans your media library and identifies every image that's missing alt text.
Generate
AI analyzes each image and writes a descriptive, SEO-friendly alt text automatically.
Done
Alt text is saved directly to your media library. Review, edit, or accept as-is.
Two Ways to Generate
Switch between modes any time in Settings. No reinstall, no separate plugin.
Local Browser AI
A compact vision model (Transformers.js) runs entirely in your browser. Images never leave your server, no API key required, and generation costs nothing per image.
Great for bulk backfills — lower accuracy than cloud AI
Bring Your Own Key
Connect your own Anthropic or OpenAI API key. AltVault sends the image directly to their API — you pay their rate, we never touch your key or your images.

Packed with Features
Everything you need to fix your image alt text, boost SEO, and improve accessibility.
Two AI Modes
Built-in browser AI (Transformers.js) for zero per-image cost, or connect your Anthropic/OpenAI key for higher accuracy. Toggle in Settings — no reinstall needed.
Bulk Processing
Process hundreds or thousands of images in one click. Real-time progress bar and live log show every result. PRO
SEO Prefixes & Suffixes
Automatically prepend or append custom text to every alt tag. Great for branding: "Photo of [alt] - YourBrand".
Auto-Generate on Upload
Every new image uploaded to your media library gets alt text automatically. Zero manual effort going forward.
Dashboard & Stats
See exactly how many images have alt text, how many are missing, and your monthly usage at a glance.
Privacy-First
In local mode, images never leave your server. In BYOK mode, images go directly to your chosen AI provider — we never store, proxy, or access them.
Max Length Control
Set a character limit (50–300) so alt text fits your SEO strategy. Auto-capitalizes the first letter.
No Ongoing Costs
One annual license, no per-image fees, no API bill. Process your entire media library — past and future — for a flat yearly price.
Auto-Updates
Licensed users get automatic updates delivered directly through WordPress. One-click update from the Plugins page.
Simple Pricing
One flat annual price. No surprise bills. Use built-in local AI (always free) or top up with AI credits.
