原文外掛簡介
AltPost is an AI alt text generator for WordPress that creates SEO-friendly image alt text for new uploads and your existing media library. There is no API key to create and no OpenAI account to manage — AltPost Managed handles the AI for you.
Start free (60 images in your first month, then 15/month), then scale with bulk generation built for WooCommerce stores, publishers, agencies, and image-heavy WordPress sites.
AltPost also includes optional AI image renaming so generic files like image-1.jpg, IMG_1234.png, or DSC0001.jpg become clear, descriptive, SEO-friendly filenames as part of the same workflow.
Built by A63 Digital, a working WordPress agency in Dublin, Ireland.
Included in this free plugin
Vision-based alt text — the AI actually sees and describes your images
Optional AI renaming of generic filenames (e.g. image-1.jpg → descriptive-slug.jpg)
Batch runner with Start / Pause / Stop controls
Inline editable results table with debounced autosave
Rollback to previous alt text with one click
Filename-as-alt detection (treats IMG_1234.jpg as missing)
Alt Text Health Score — 0–100 site score with issue filters
Compliance Report export (Print/PDF + CSV) for alt text documentation
WPML and Polylang compatible — alt text in every language of your site
Batch history with one-click undo for entire runs
Optional sync of alt text into post content (Gutenberg, classic, Elementor) — off by default
WP-CLI: wp altpost scan, generate, and rollback
Compatibility with major page builders (Gutenberg, Elementor, Beaver Builder, Divi, WPBakery, Bricks, Oxygen)
Cache plugin support (WP Rocket, W3 Total Cache, LiteSpeed Cache, and others)
Use AltPost as an alt text checker: it scans your media library for images with missing alt text or filename-based placeholders such as IMG_1234.jpg, then lets you generate proper descriptions for those images in bulk.
Meaningful alt text is required under WCAG 2.1 and the European Accessibility Act (in force since June 2025). AltPost helps WordPress sites meet those accessibility requirements by generating accurate, human-readable alt text at scale.
Free tier (service credits)
New free registrations get 60 AI-generated images in their first calendar month, then 15 images per month after that — register your email during setup (no credit card required). Credits are enforced by the AltPost Managed API (api.a63.ai), not by locking PHP features inside this plugin.
AltPost Pro (separate plugin — not in this zip)
Advanced features (context-aware SEO alt text, background processing, Image Manager, Broken Image Scanner, title & description generation, higher monthly limits) ship in a separate AltPost Pro plugin from a63.ai/altpost. This WordPress.org build does not include those modules and does not gate them behind a license key.
External services
This plugin connects to AltPost Managed at https://api.a63.ai.
When you generate alt text, the plugin sends a request to https://api.a63.ai/api/altpost/v1/vision. Each request includes:
the public URL of the image being described
the requested quality tier, language, and maximum length
your site URL and the plugin version (sent as request headers)
The service calls an AI vision provider on your behalf, tracks your monthly credit usage, and returns the generated text plus your remaining credits. Images are not retained after processing.
Free-tier users also submit a registration request to https://api.a63.ai/api/altpost/v1/register-free during setup. This sends your email address, site URL, plugin version, and optional marketing consent preference (opt-in only — not required to use the free tier).
