AI Alt Text Builder

AI Alt Text Builder is a WordPress plugin for generating image descriptions in the Media Library. It is best suited to WordPress site owners managing sizable libraries who want to process images in batches or as they arrive. Its appeal is a workflow built into WordPress; its monthly token caps and limited platform reach make it less suitable for teams needing an independent service or API.

Overview

A Generate with AI button appears on Media Library items and their attachment edit screens. Results are saved to WordPress’ standard alt text field, where themes and other plugins can read them. A 0–100 length score and sortable Media Library column give users a way to review and organize generated text, though the score measures length rather than describing a broader quality check.

Key features

Paid plans include bulk generation, and Pro adds automatic generation on upload. These are useful for both clearing a backlog and keeping up with new images, but monthly token allowances limit how much work fits into each billing period. Unused tokens expire when the allowance resets.

The model selector offers GPT-4.1 Mini, GPT-4.1 and GPT-4o. Language choices include English, German, French, Spanish, Turkish and a custom language; Pro adds custom prompts, all languages and all models. That flexibility helps teams shape output for their audience, while users on cheaper plans have fewer ways to tailor generation.

Trial and Pro generation send image URLs to RankPilotAI. BYOK mode can send them directly to OpenAI instead. In Pro mode, RankPilotAI receives the image URL, file name, current alt text, chosen model and language, site URL, domain, plugin slug and Site Token. RankPilotAI’s privacy policy describes encryption in transit, least-privilege access controls and regular security audits. Those safeguards may matter to site owners, but the data flow still deserves review for images or site information they consider sensitive.

Pricing

The Free plan costs nothing and includes 25 free tokens. Supplying your own OpenAI API key allows unlimited single-image generations, making this a practical way to try the WordPress workflow; it does not provide the paid plan’s bulk generation.

Starter costs $2.99 a month (billed yearly) and provides 100 tokens/month for 1 website, bulk generation and the three listed models. Creator costs $7.99 a month (billed yearly), raises the allowance to 400 tokens/month and covers 5 websites. Expert costs $17.99 a month (billed yearly), with 1,200 tokens/month and 25 websites. All three paid plans reset tokens monthly and forfeit unused tokens at reset. Starter suits a single site with modest recurring volume; Creator and Expert fit multi-site operators or those with more images to process, though their larger quotas still require planning around monthly use.

Institutional has custom pricing and includes unlimited sites and departments, high-volume monthly generation, bulk backlog remediation, a WCAG compliance report, PO/invoice billing, SSO and priority support. It is aimed at organizations with broader deployment and procurement needs. The product also advertises a price from $4.99/mo (annual), while the listed Starter plan is $2.99 a month billed yearly.

Platforms

This is a WordPress plugin, with WordPress 6.0 or later, PHP 8.0 or later and a RankPilotAI Site Token required. The plugin’s output fits the standard WordPress attachment field, but there is no API access, so developers seeking to connect generation to a separate system should look elsewhere. Documentation lists email and Slack support.

Who it's for

The product is described for large image libraries on e-commerce sites, blogs and corporate websites. It is a sensible fit when the work already happens in WordPress and batch or upload automation can save repetitive effort. Sites using another CMS, or teams that need API-driven publishing, have a weaker fit.

Pros and cons

• Pros: Bulk processing and upload automation connect generation to both existing and incoming WordPress images.
• Pros: Standard-field output remains readable by WordPress themes and plugins, with a sortable column and length score for review.
• Pros: BYOK mode can route image URLs directly to OpenAI, and the Free plan allows unlimited single-image generation with an OpenAI key.
• Cons: The plugin requires a compatible WordPress and PHP setup plus a Site Token, limiting its usefulness outside that environment.
• Cons: Paid monthly quotas expire at reset, which can make uneven workloads less efficient.
• Cons: RankPilotAI receives image and site-related data in Pro mode, and there is no API access for teams building a separate workflow.
