Same question here: Is Siri AI designed to work with Custom App Intents that don't fit within any of the schemas, or not? I imagine a lot of developers will have this question, but the documentation on it is ambiguous and at times contradictory. It would be great to get clarification. For posterity, I looked at the following resources: WWDC 26 Videos Skimmed through all videos relating to Siri AI, didn't see any mention of Custom App Intents (might've missed it) Doc: "Getting Started With The App Intents Framework" https://developer.apple.com/documentation/appintents/getting-started-with-the-app-intents-framework Mentions this, which seems to imply the possibility of Apple Intelligence and Siri working with custom app intents: Apple Intelligence and Siri AI work better for app intents that support a known schema. Doc: "Making actions and content discoverable by Apple Intelligence" https://developer.apple.com/documentation/appintents/making-actions-and-content-discoverable-by-apple-intelligence No mention of custom app intents.
