When you upload an image, it generates accurate, accessible **alt text** by looking at the picture. When you save a post, it can write an SEO **meta description** and add **JSON-LD structured data**. Turn it on once and it keeps your media and content described as your site grows. Unlike most tools, **you don’t need your own AI API key** — the AI runs on the Altograph service, so there’s nothing to configure. The free plan covers 25 items per month; Altograph Pro removes the monthly limit (subject to fair use). **What it does** * Generates descriptive alt text for images from the image itself (better accessibility and image SEO). * Writes concise, on-topic meta descriptions for posts and pages. * Adds Article JSON-LD structured data for richer search results. * Backfills alt text for images that are currently missing it. * Never overwrites alt text you’ve written yourself. **Privacy-friendly by design** Automation is **off until you switch it on**, and Altograph only ever sends what it needs to do the job (see the External Services section below). A non-identifying site ID — a hash of your site URL — is used for usage counting; no personal data is required. ### External services This plugin connects to the **Altograph API** to generate alt text and metadata. It is required for the plugin’s core features. * **What is sent and when:** - _Alt text:_ when you upload an image (with automation on), run the backfill action, the plugin sends the **image URL** and **filename** to the Altograph API. - _Meta descriptions:_ when you save a post or page (with automation on), the plugin sends the **post title** and **post content**. - _Usage counting:_ a non-identifying **site ID** (a hash of your site URL) accompanies each request. * **Where it goes:** the Altograph API (default `https://api.thereallyusefulappcompany. com`), which uses **Anthropic** as an AI subprocessor to generate the text. * **Service terms and privacy:** - Altograph Terms: https://thereallyusefulappcompany.com/altograph/terms - Altograph Privacy Policy: https://thereallyusefulappcompany.com/altograph/ privacy - Anthropic Privacy Policy: https://www.anthropic.com/legal/privacy No data is sent until you enable automation, click the backfill button, or save a post while automation is enabled. ## 螢幕擷圖 [⌊The Altograph settings screen with the external-service notice and automation toggles.⌉⌊The Altograph settings screen with the external-service notice and automation toggles.⌉[ The Altograph settings screen with the external-service notice and automation toggles.

Install Altograph from the Plugins screen, or upload the `altograph` folder to `/ wp-content/plugins/`. 2. Activate the plugin. 3. Go to **Settings Altograph**. 4. Review the external-service notice, then enable “Write alt text automatically” and/or “Write a meta description automatically.” 5. (Optional) Enter a Altograph Pro licence key to remove the monthly limit. ## 常見問題集 ### Do I need an AI API key? No. The AI runs on the Altograph service, so there’s nothing to set up. ### Will it overwrite alt text I’ve already written? No. Altograph only fills in alt text that is missing. ### Is anything sent automatically without my knowledge? No. Automation is off by default. Data is only sent after you enable it, and exactly what’s sent is listed in the External Services section. ### What happens when I hit the free limit? Generation pauses for the rest of the month. Upgrade to Pro for unlimited use, or wait for the next month. ## 使用者評論 這個外掛目前沒有任何使用者評論。 ## 參與者及開發者 以下人員參與了開源軟體〈Altograph — Alt Text & SEO Autopilot〉的開發相關工作。 參與者 * [ The Really Useful App Company ](https://profiles.wordpress.org/reallyusefulappco/) [將〈Altograph — Alt Text & SEO Autopilot〉外掛本地化為台灣繁體中文版](https://translate.wordpress.org/projects/wp-plugins/altograph) ### 對開發相關資訊感興趣？ 任何人均可[瀏覽程式碼](https://plugins.trac.wordpress.org/browser/altograph/)、查看 [SVN 存放庫](https://plugins.svn.wordpress.org/altograph/)，或透過 [RSS](https://plugins.trac.wordpress.org/log/altograph/?limit=100&mode=stop_on_copy&format=rss) 訂閱[開發記錄](https://plugins.trac.wordpress.org/log/altograph/)。 ## 變更記錄 #### 1.0.0 * Initial release: automatic alt text, meta descriptions, JSON-LD, and backfill. ## 中繼資料 * 版本 **1.0.0** * 最後更新 **3 天前** * 啟用安裝數 **少於 10 次** * WordPress 版本需求 ** 6.0 或更新版本 ** * 已測試相容的 WordPress 版本 **7.0** * PHP 版本需求 ** 7.4 或更新版本 ** * 語言 * [English (US)](https://wordpress.org/plugins/altograph/) * 標籤: * [accessibility](https://tw.wordpress.org/plugins/tags/accessibility/)[Alt Text](https://tw.wordpress.org/plugins/tags/alt-text/) [meta description](https://tw.wordpress.org/plugins/tags/meta-description/)[seo](https://tw.wordpress.org/plugins/tags/seo/) [structured data](https://tw.wordpress.org/plugins/tags/structured-data/) * [進階檢視](https://tw.wordpress.org/plugins/altograph/advanced/) ## 評分 這個項目尚無任何評論記錄。 [Your review](https://wordpress.org/support/plugin/altograph/reviews/#new-post) [查看全部使用者評論](https://wordpress.org/support/plugin/altograph/reviews/) ## 參與者 * [ The Really Useful App Company ](https://profiles.wordpress.org/reallyusefulappco/) ## 技術支援 使用者可在技術支援論壇提出意見反應或使用問題。 [檢視技術支援論壇](https://wordpress.org/support/plugin/altograph/)
