AI Alt Text Builder vs Altvisor

AI Alt Text Builder is a WordPress plugin that generates descriptive alternative text for images in the Media Library. It adds a one-click generation control to individual media items and their attachment edit screens. Pro adds bulk generation and automatic generation when an image is uploaded. Generated text receives a length score from 0 to 100, with a sortable column in the Media Library for review. Model choices include GPT-4.1 Mini, GPT-4.1, and GPT-4o; language options include English, German, French, Spanish, Turkish, or a custom language. Pro includes custom prompts, all listed models, and all listed languages. Output is saved in WordPress’ standard attachment alt text field, which themes and other plugins can read. During trial or Pro generation, image URLs are sent to RankPilotAI; BYOK mode can send them directly to OpenAI. In Pro mode, RankPilotAI also receives the file name, current alt text, selected model and language, site URL, domain, plugin slug, and Site Token. Requirements are WordPress 6.0 or later, PHP 8.0 or later, and a RankPilotAI Site Token. The free plan includes 25 tokens; annual plans start at $2.99 a month.

Altvisor is a web tool for generating image alt text and coordinating accessibility work for EU e-commerce sites. It drafts descriptions against WCAG 2.1 Level AA in all 24 official EU languages, with a person able to review and edit each suggestion before publishing. Its scanner checks alt text, headings, semantic structure, and language tags, then provides an AI visibility score; every plan includes a free scan. The product can prepare accessibility statements and compliance reports from scan results, but statements are self-declarations rather than certificates. Users can import images from websites and connect WordPress or WooCommerce. Shopify and WordPress plugins, a Chrome extension, and API documentation are marked as coming soon. Free costs nothing and covers 50 images monthly on one website, without an accessibility statement. Starter costs €12 a month, billed €144/yr, and covers 600 images monthly across two sites. Growth costs €36 a month, billed €432/yr; Business costs €76 a month, billed €912/yr. Altvisor says its AI inference remains in the EU, and uploaded images are processed in memory and deleted from storage.
