原文外掛簡介
AltTide writes accurate, descriptive image alt text for your whole media library, great for accessibility (screen readers, WCAG, the EU Accessibility Act) and for image SEO. Bring your own API key and pick the AI you trust: OpenAI (GPT), Anthropic Claude, or Google Gemini.
Unlike credit-based tools, there are no per-image fees. You use your own provider key, so bulk-fixing a whole library costs only what your provider charges, often a fraction of a cent per image.
Everything in the four areas below is included in the free plugin.
🤖 AI alt text, your way
Three providers: OpenAI GPT, Claude, and Gemini (choose per site; pick a model from the current list or enter any newer one, with a link to each provider’s model page)
Bulk generate alt text for every image missing it, processed one at a time so your provider account is never hammered
Regenerate on demand: a “Has alt text” view lets you hand-pick images that already have alt text and regenerate them with your current provider and model, for example after switching models
Generate on upload, so new images get alt text automatically
Non-AI quick fill from the filename when you do not need a full description
🖼️ Right where you work
Media dashboard with a coverage score, a “missing alt text” list, a “has alt text” list, and a per-image Generate button
In the media library: “Generate with AI” and “Use filename” buttons right inside the media modal and the attachment editor
Mark images as decorative (WCAG): give logos, dividers and spacers an empty alt so screen readers skip them; decorative images are left out of the missing count and skipped by generation
Activity log: an in-dashboard feed of what AltTide did (alt text, metadata, file renames, decorative marks), with one-click clear
🔍 Built for image SEO
SEO focus-keyphrase integration that reads the keyphrase from Yoast, Rank Math, All in One SEO and SEOPress to steer generation
Image metadata: optionally also generate each image’s title, caption and description (standard WordPress attachment fields) in the same pass
SEO-friendly file names: optionally rename new uploads from their generated alt text, so IMG_4821.jpg becomes blue-ceramic-vase.jpg. New uploads only, so no existing URL can break
🔒 Safe and flexible
Safer key handling: each provider key is masked on reload, with an eye button to reveal it and a one-click delete
Multilingual: auto-detect the page language, or write in a language you choose
Works everywhere: brand-casing preservation, WP-CLI, and multisite compatible
🚀 Pro
AltTide Pro adds automation and deeper image SEO:
Image SEO report with scores: every image graded from 0 to 100 across six checks (has alt text, good length, not just the filename, a descriptive file name, the focus keyphrase, and uniqueness), with a sortable report and CSV export.
WooCommerce and Easy Digital Downloads context: alt text that uses the product name, category and attributes for commerce-aware descriptions.
OpenGraph image meta: generate the social-share image description so shared pages look right.
Scheduled bulk runs: process your whole library automatically on a schedule, in safe batches.
Brand-voice templates: set a tone, a context strength, and a prefix and suffix so every description matches your brand.
More AI providers: add OpenRouter (hundreds of models through one key) or any custom OpenAI-compatible endpoint.
Role access: let chosen non-admin roles use AltTide.
Agency and multisite: white-label AltTide and manage alt text across a multisite network.

Your API keys are stored in your own database and sent only to the provider you choose. This plugin is not affiliated with OpenAI, Anthropic or Google.
External services
This plugin generates text by calling the AI provider you configure. No request is made until you enter an API key and start a generation, and only the one provider you select is contacted.
What is sent: the image (or its URL) you are generating for, a short text prompt built from the image context (such as the attached post title and focus keyphrase), and your API key for that provider. Nothing is sent to ShoreZella.
The provider you choose, and its terms and privacy policy:
OpenAI (api.openai.com) – Terms, Privacy
Anthropic (Claude) (api.anthropic.com) – Terms, Privacy
Google Gemini (generativelanguage.googleapis.com) – Terms, Privacy
The “Our plugins” screen shows other plugins we make. To build that list it makes two read-only catalog requests, only when you open that screen, and caches the result: one to WordPress.org (api.wordpress.org, the same directory WordPress itself uses) for our free plugins, and one to the ShoreZella store (shorezella.com) for our paid add-ons. No information about your site is sent in either request; they only fetch a public product list.
ShoreZella (shorezella.com) – Terms, Privacy
Fonts and scripts are bundled with the plugin and loaded locally, so the plugin itself makes no other outside requests.
