AI Services vs DiagnoSEO – Fast and Automated On-page SEO

This WordPress plugin introduces central infrastructure which allows other plugins to make use of AI capabilities. It exposes APIs that can be used in various contexts, whether you need to use AI capabilities in server-side or client-side code. Furthermore, the APIs are agnostic of the AI service – whether that’s Anthropic, Google, or OpenAI, to only name a few, you can use any of them in the same way. You can also register your own implementation of another service, if it is not supported out of the box. The plugin does intentionally not come with specific AI driven features built-in, except for an AI Playground screen to explore AI capabilities as well as a settings screen to configure AI service credentials. The purpose of this plugin is to facilitate use of AI by other plugins. As such, it is a perfect use-case for plugin dependencies. Here’s a (non-comprehensive) feature list: Abstraction layer and APIs to communicate with any AI service in a uniform way APIs are available in both PHP and in JavaScript, as well as via the WordPress REST API and WP-CLI commands Currently supports the following AI capabilities (with more on the way!): text generation (including text streaming for more immediate feedback to users) text chats with history multimodal input function calling image generation AI Playground administration screen (in the Tools menu) allows exploring the different AI capabilities Explore all AI capabilities supported by the plugin via user interface Select which AI service and model to use and set a few advanced configuration parameters Define your own function declarations used for AI function calling Generate images and save them to the WordPress media library Exchange the AI service or model on the fly to continue a chat started with one model with another one AI Services settings screen to configure services with API credentials Built-in AI service implementations Anthropic (Claude) Google (Gemini, Imagen) Mistral OpenAI (GPT, Dall-E) Perplexity (Sonar) xAI (Grok) Browser (client-side only; experimental support for Chrome’s built-in AI APIs and Edge’s built-in AI APIs) Additional AI service integrations can be registered and will then be available in the same way as built-in ones Disclaimer: The AI Services plugin is still in its early stages, with a limited feature set and more being added. A crucial part of refining the plugin is shaping the APIs to make them easy to use and cover the different generative AI capabilities that the AI services offer in a uniform way. That’s why your feedback is much appreciated! Why? A centralized AI infrastructure facilitates user choice. Users may prefer certain AI services over other ones, and for many common tasks, either of the popular AI services is suitable. Having a common API regardless of the AI service allows leaving the choice to the user, rather than the plugin author. Since the centralized AI infrastructure comes with a common API that works the same for every AI service, it means plugin developers don’t have to spend as much time familiarizing themselves with different services, at least when it comes to simple tasks. For tasks where certain services may have advantages over others, there is still flexibility to focus on a specific AI service. It also means no more reinventing the wheel: Since most AI services do not provide PHP SDKs for their APIs, many times this means WordPress plugins that want to leverage AI have to implement their own layer around the service’s API. Not only is that time consuming, it also distracts from working on the actual (AI driven) features that the plugin should offer to its users. In fact this directly facilitates the user choice aspect mentioned, as having APIs for various AI services already provided means you can simply make those available to your plugin users. Having central AI infrastructure available unlocks AI capabilities for smaller plugins or features: It may not be worth the investment to implement a whole AI API layer for a simple AI driven feature, but when you already have it available, it can lead to more plugins (and thus more users) benefitting from AI capabilities. Last but not least, a central AI infrastructure means users will only have to configure the AI API once, e.g. paste their API keys only in a single WordPress administration screen. Without central AI infrastructure, every plugin has to provide its own UI for pasting API keys, making the process more tedious for site owners the more AI capabilities their site uses. Integration with third party services While the plugin APIs allow registering custom AI services, the plugin comes with a few popular AI services built-in. These AI services rely on the respective third party API. Their use is optional and it is up to you to choose which third party service you would like to use or whether you would like to use multiple. The use of the third party AI services is subject to the respective terms of service. The following third party services are supported out of the box: Anthropic (Claude) Anthropic Consumer Terms of Service Anthropic Commercial Terms of Service Anthropic Privacy Policy Google (Gemini, Imagen) Google Terms of Service Google AI Terms of Service Google Privacy Policy Mistral Mistral Terms of Service Mistral Privacy Policy OpenAI (GPT, Dall-E) OpenAI Terms of Use OpenAI Privacy Policy Perplexity (Sonar) Perplexity Terms of Service Perplexity Privacy Policy xAI (Grok) xAI Terms of Service – Consumer xAI Terms of Service – Enterprise xAI Privacy Policy Code examples for using the API Generate the answer to a prompt in PHP code: use Felix_Arntz\AI_Services\Services\API\Enums\AI_Capability; use Felix_Arntz\AI_Services\Services\API\Helpers; if ( ai_services()->has_available_services() ) { $service = ai_services()->get_available_service(); try { $candidates = $service ->get_model( array( 'feature' => 'my-test-feature', 'capabilities' => array( AI_Capability::TEXT_GENERATION ), ) ) ->generate_text( 'What can I do with WordPress?' ); $text = Helpers::get_text_from_contents( Helpers::get_candidate_contents( $candidates ) ); echo $text; } catch ( Exception $e ) { // Handle the exception. } } Generate the answer to a prompt in JavaScript code: const helpers = aiServices.ai.helpers; const { hasAvailableServices, getAvailableService } = wp.data.select( 'ai-services/ai' ); if ( hasAvailableServices() ) { const service = getAvailableService(); try { const candidates = await service.generateText( 'What can I do with WordPress?', { feature: 'my-test-feature' } ); const text = helpers.getTextFromContents( helpers.getCandidateContents( candidates ) ); console.log( text ); } catch ( error ) { // Handle the error. } } Generate the answer to a prompt using WP-CLI: wp ai-services generate-text "What can I do with WordPress?" --feature=my-test-feature You can also use a specific AI service, if you have a preference, for example the google service. Generate the answer to a prompt using a specific AI service, in PHP code: use Felix_Arntz\AI_Services\Services\API\Enums\AI_Capability; use Felix_Arntz\AI_Services\Services\API\Helpers; if ( ai_services()->is_service_available( 'google' ) ) { $service = ai_services()->get_available_service( 'google' ); try { $candidates = $service ->get_model( array( 'feature' => 'my-test-feature', 'capabilities' => array( AI_Capability::TEXT_GENERATION ), ) ) ->generate_text( 'What can I do with WordPress?' ); $text = Helpers::get_text_from_contents( Helpers::get_candidate_contents( $candidates ) ); echo $text; } catch ( Exception $e ) { // Handle the exception. } } Refer to the plugin documentation for granular examples including explainers.
