Pricing

Note that there is no cost to using ClassifAI and that both IBM Watson and Microsoft Azure have free plans for their AI services, but that above those free plans there are paid levels as well. So if you expect to process a high volume of content, then you'll want to review the pricing plans for these services to understand if you'll incur any costs. For the most part, both services' free plans are quite generous and should at least allow for testing ClassifAI to better understand its featureset and could at best allow for totally free usage.

The service that powers ClassifAI's Language Processing, IBM Watson's Natural Language Understanding ("NLU"), has a "lite" pricing tier that offers 30,000 free NLU items per month.

The service that powers ClassifAI's Image Processing, Microsoft Azure's Computer Vision, has a "free" pricing tier that offers 20 transactions per minute and 5,000 transactions per month.

Set Up Language Processing (via IBM Watson)

1. Sign up for Watson services

• Register for an IBM Cloud account or sign into your existing one.
• Check for an email from IBM Cloud and click the Confirm Account link.

• In the API URL field enter the URL
• Enter your API Key in the API Key field.

If your credentials contain a username and password, then:

• In the API URL field enter the URL
• Enter the username value into the API Username.
• Enter the password into the API Key field.

Frequently Asked Questions

What data does ClassifAI gather?

ClassifAI connects your WordPress site directly to your account with specific service provider(s) (e.g. Microsoft Azure AI, IBM Watson), so no data is gathered by 10up. The data gathered in our registration form is used simply to stay in touch with users so we can provide product updates and news. More information is available in the Privacy Policy on ClassifAIplugin.com.

What are the Categories, Keywords, Concepts, and Entities within the Language Processing feature?

Categories are five levels of hierarchies that IBM Watson can identify from your text. Keywords are specific terms from your text that IBM Watson is able to identify. Concepts are high-level concepts that are not necessarily directly referenced in your text. Entities are people, companies, locations, and classifications that are made by IBM Watson from your text.

How can I view the taxonomies that are generated from Language Processing?

Whatever options you have selected in the Category, Keyword, Entity, and Concept taxonomy dropdowns in the Language Processing settings can be viewed within Classic Editor metaboxes and the Block Editor side panel. They can also be viewed in the All Posts and All Pages table list views by utilizing the Screen Options to enable those columns if they're not already appearing in your table list view.

Support Level

Active: 10up is actively working on this, and we expect to continue work for the foreseeable future including keeping tested up to the most recent version of WordPress. Bug reports, feature requests, questions, and pull requests are welcome.
