Three Steps to Full Compliance

From install to optimised — AltGenius works silently in the background, so you can focus on what you do best.

01

Install & Connect

Install from the WordPress plugin directory in seconds. Connect your API key and you're ready. No technical knowledge required — it just works.

02

AI Analyses Every Image

Our vision model reads your images — understanding context, scene, subject, mood, and brand voice. It generates alt text that a human would be proud to write.

03

Watch Scores Climb

Accessibility, SEO, AEO, and GEO metrics lift automatically. Track improvement in your dashboard and watch your site outrank the competition.

Everything Your Images Need

Built for agencies, freelancers, and in-house teams who take performance seriously.

Context-Aware Alt Text Generation

Our AI doesn't just describe pixels — it understands your page context, industry, and brand tone. A product image on an e-commerce page gets different treatment than the same image in a blog post. Every description is purposeful, precise, and keyword-rich.

Questions Answered

AEO (Answer Engine Optimisation) means structuring your content so AI assistants like ChatGPT, Perplexity, and Google AI Overviews can understand and cite it. GEO (Generative Engine Optimisation) goes further — it ensures your images and their descriptions appear within AI-generated results. With over 30% of searches now using AI answers, this is the next frontier of SEO.
Yes. AltGenius operates at the WordPress media library level — it doesn't matter whether you use Elementor, Divi, Gutenberg, WooCommerce, or a custom theme. Any image stored in your media library can be processed, and the alt text updates everywhere that image is used automatically.
Never without your permission. You can choose to run it only on images that have no alt text, or review and approve generated text before it's saved. A full override mode is also available for bulk re-optimisation, with a one-click restore to the previous version.
Our AI model is trained on WCAG 2.2 guidelines and fine-tuned on thousands of expert-written alt text examples. It avoids common failures like redundant phrases ("image of…"), missing context, and over-description. Each generated text is scored internally and only published when it meets our compliance threshold.
Absolutely. Images are sent to our processing API over HTTPS, used only for alt text generation, and never stored or used for AI training. We are GDPR compliant and SOC 2 Type II certified. Your data remains yours, always.
Our Agency plan is designed exactly for this. It supports multi-site management, white-label accessibility and SEO reports you can send directly to clients, and team member access. Many agencies use AltGenius as a billable service add-on.
