AltoGraph
A Really Useful WordPress plugin
Alt text & SEO metadata, written automatically.
AltoGraph adds AI-written image alt text, SEO meta descriptions, and structured data to your WordPress site, working the moment you activate it. No API key. No account. No setup.
Now live and free on the WordPress.org plugin directory.
What it does
Three jobs every site needs for accessibility and search: handled for you, on autopilot or on demand.
Image alt text
Descriptive, accurate alt text for every image: better accessibility for screen-reader users and a quiet SEO win. It never overwrites alt text you've written yourself.
Meta descriptions
Clear, search-friendly meta descriptions generated from your post's title and content, kept within the length search engines actually display.
Structured data
Valid JSON-LD structured data so search engines understand your pages, output only when it's well-formed, so it helps rather than hurts.
No API key. We host the AI.
Every other AI plugin makes you sign up for an AI provider, generate your own API key, and pay them separately. AltoGraph doesn't. The AI runs on our backend, so it works the instant you activate the plugin: nothing to configure, nothing extra to pay for. That's the whole point.
