Overview
AltText Buddy is an accessibility power-tool that automatically generates descriptive alt text for images in your WordPress Media Library using five leading AI providers — all with generous free tiers. Supports Google Cloud Vision (1,000 free requests/month), Microsoft Azure Computer Vision (5,000 free transactions/month), Clarifai (1,000 free calls/month), ChatGPT via OpenAI, and Claude via Anthropic. Features include individual one-click generation with inline editing, bulk processing with real-time progress tracking and detailed results summary, smart filtering of generic terms, people detection and counting, text recognition, and intelligent fallback to image filename when API returns minimal results. Detects localhost environments automatically and uses base64 encoding for local image delivery. API keys are stored securely in the WordPress database.

Deep Dive
Smart Filtering Engine
The API response is post-processed to remove generic labels (e.g. "image", "photo"), boost people/text/object detection confidence, and apply intelligent filename fallback when the vision result is low-confidence.
Localhost Base64 Support
On local development environments, images cannot be fetched via public URL. AltText Buddy automatically detects localhost and sends the image as base64-encoded data to Google Vision and Clarifai.
5 Providers, 1 Interface
Switch between Google Cloud Vision, Azure Computer Vision, Clarifai, ChatGPT, or Claude from a single settings screen. Per-provider setup guides are shown inline — no separate documentation tab.
WCAG Accessibility Workflow
Designed for accessibility teams and developers who need to bring a media library up to WCAG 2.1 AA compliance. Regenerate button appears automatically on images that already have alt text.
How It Works
STEP 01
Choose your AI provider
Go to Settings > AltText Buddy, pick one of the five supported providers, paste your free-tier API key, and click Test Connection. Setup takes about 2 minutes.
STEP 02
Generate alt text individually
Open any image in the Media Library. Click "Generate Alt Text". The AI analyses the image, filters generic terms, and returns a descriptive result.
STEP 03
Review, edit, and save
A modal shows the generated alt text before saving. Edit directly in the field, copy to clipboard, or regenerate with a different provider. Nothing is auto-saved without your approval.
STEP 04
Bulk process your library
Open AltText Buddy > Bulk Process. Select all images (or a subset), hit Generate — and watch a real-time progress tracker work through your library with per-image status and a results summary.
