Plugin Description

Presswell Alt Text Generator helps teams reduce accessibility backlog by generating descriptive alt text for new and existing images. Connect a provider, choose a model, and run generation workflows directly inside wp-admin.

Features

• Supports OpenAI, Anthropic Claude, and Google Gemini multimodal models
• Generates alt text for individual images in the Media Library and media modal
• Processes missing-alt backlogs in batches with a dedicated bulk queue
• Handles provider rate limits with automatic cooldown locks
• Adds a Media Library column with quick generate/regenerate actions
• Provides a customizable prompt seed for output consistency

Media Library Tools

Inline actions let you generate or regenerate alt text directly from each image row. When an image has no alt text, the column displays a “Generate Alt Text” link that triggers the AJAX workflow and replaces itself with the result.

Bulk Generator

The Bulk page counts images missing alt text, allows regeneration preferences, and runs batches while surfacing progress, failures, and rate-limit pauses.

Privacy

This plugin sends image-derived payloads to the AI provider you choose when generating alt text (OpenAI, Anthropic, or Google Gemini). API keys are stored in WordPress options on your site and used only for outbound provider requests initiated by your server.

External Services

This plugin connects to external AI services only when you use alt text generation features or test provider connectivity. Only the provider selected in plugin settings is contacted for a given request. This plugin sends the follow data:

• API key (in Authorization header)
• Selected model name
• Prompt text (including your prompt seed and filename context)
  • For alt-text generation: image MIME type and image binary content encoded as base64
  • For Test Connection: a short text prompt (“Reply with: OK”)
