详情介绍:
No API key. No account. No setup. Unlike most AI tools, which make you sign up for OpenAI or Anthropic and paste in your own paid API key, AltoGraph runs the AI on our hosted service. Free for 25 items every month.
Your Media library gets an Alt text column, so you can see at a glance which images have none, and a Generate button on each one that does not. One click writes alt text from the picture itself. There is a bulk action for a backlog, and a Generate button in the Attachment details panel too.
Nothing is sent anywhere until you ask for it. If you would rather not click, you can switch on automatic alt text for new uploads, and automatic SEO meta descriptions with JSON-LD structured data when you save a post, in Settings. Both are off until you turn them on. AltoGraph never overwrites alt text you have written yourself.
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.
安装:
- Install AltoGraph from the Plugins screen, or upload the
altographfolder to/wp-content/plugins/. - Activate the plugin.
- Go to Settings → AltoGraph.
- Review the external-service notice, then enable "Write alt text automatically" and/or "Write a meta description automatically."
- (Optional) Enter a AltoGraph Pro licence key to remove the monthly limit.

常见问题:
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.
更新日志:
1.0.20
- Fixed: a licence key that our service does not recognise is no longer shown as "Pro". The plugin now says the key was not recognised and keeps the upgrade link visible, instead of silently putting you on the free allowance with no way to correct it.
- Changed: your licence key is no longer shown in full or left in an editable box. Settings now shows only the last four characters, and replacing the key takes a deliberate click on "Update key", so it cannot be typed over by accident. Removing a key is its own checkbox.
- Fixed: the address the plugin uses to reach our AI service is now required to be https, both when it is saved and every time it is read. Only an administrator could ever have changed it, and the default has always been secure, but an insecure address entered by hand would have sent your licence key and your content unencrypted. An address that is not https is now refused and the secure default is used instead.
- Fixed: the result message shown after generating alt text in the Media library travelled in the page address, so a link crafted by someone else could put their own wording inside a message labelled AltoGraph. The message is now held for your account only and the address carries nothing but a short reference.
- Fixed: the structured data AltoGraph adds to your page header is now escaped more strictly, so generated text cannot affect the surrounding page whatever it contains. It also no longer passes through a filter that could alter an ampersand inside the data and make it invalid.
- Fixed: the error token in the Media library address is now sanitised where it is read, matching the rest of the family. No visible change.
- Fixed: on the Edit Media screen, Generate alt text did nothing when clicked. The button now works there as it does in the Media library.
- Changed: the notes beside the Generate controls now describe what the button will do, rather than reading as a claim that text already on the page was written by AI.
- Added: a Settings link on the Plugins screen. The welcome notice now uses the same shared component as the rest of the family, so all four behave identically.
- Added: the plugin now reports whether this site's review prompt was shown, snoozed, dismissed or clicked, so we can tell whether the prompt is working at all. It rides the request the plugin already makes, so no new outbound request is made and no new action triggers a send. It records the site rather than the individual user, and nothing about what happens on WordPress.org afterwards.
- Housekeeping: documented why the alt-text backfill query is written the way it is. No functional change.
- Added: the review prompt now appears in the Media library, where alt text is actually generated, instead of only on the settings screen.
- Added: the plugin now reports its own version with each request, so we can tell which release a problem relates to. No personal data is involved.
- Improved: the External services section now lists every action that sends an image, rather than two of them. Nothing about what is sent has changed.
- New: an "Alt text" column in the Media library shows at a glance which images are missing alt text, with a "Generate with AltoGraph" button on each one.
- New: a "Generate alt text" button in the Attachment details panel, right beside the Alternative Text field, so it works from the grid view too.
- New: a welcome message after activation, pointing at the Media library. Previously the plugin activated silently and gave no sign it was there.
- New: "Generate alt text" also appears as a row action and as a bulk action for several images at once.
- New: the Media library now reports what happened - how many images were given alt text, how many were skipped because they already had it, and why any failed. Reaching the monthly limit now says so instead of failing quietly.
- Fixed: when the service cannot reach an image - a private or password-protected site, hotlink protection, a moved file - it names the image from its filename instead. That is now clearly reported as NOT AI-written, with a prompt to rewrite it. Previously it was reported as a success and labelled AI-generated, which was misleading: filename text does not describe the picture and is no use to a screen-reader user.
- Unchanged: nothing is sent to the AI until you ask for it. Automation is still off by default, and existing alt text is never overwritten.
- Compatibility: tested with WordPress 7.1.
- New: a "Your usage" panel on the settings screen showing how much of this month's allowance you have used, with a progress bar.
- New: an "Upgrade to Pro" link on the settings screen for free-plan users.
- Reaching the monthly limit is now visible on the settings screen; previously the plugin stopped generating with no indication of why.
- Small wording tidy-ups on the settings screen.
- Renamed to AltoGraph (capital G) to match the rest of the Really Useful App Company family. Same plugin and settings; display name only.
- Refreshed the plugin icon and banner with the new family look.
- Added an optional, dismissible prompt on the settings page inviting an honest review after you've generated a few times. No tracking; dismiss any time.
- Added: AltoScribe to the list of our other plugins shown on the settings screen.
- Added: AltoFAQ to the list of our other plugins shown on the settings screen.
- Updated: plugin name and listing details so it's easier to find and clearer about what it does.
- Added: a reminder to review AI-generated content for accuracy before publishing (settings screen and generate actions).
- Added: links to our other Really Useful App Company plugins on the settings screen (dismissible, no tracking).
- Initial release: automatic alt text, meta descriptions, JSON-LD, and backfill.
