The Advantage of Native AppIntents
In iOS 18, Apple introduced deep enhancements to the AppIntents framework, bridging Siri voice control with on-device machine learning workflows.
For reaction recording, voice control is not a gimmick—it is a critical usability feature. When you are already comfortable on the couch with a blanket, drinks, or snacks, getting up to tap a screen breaks immersion. With Siri integration, your phone can rest on the coffee table while you manage the entire session hands-free.
Native Voice Commands Supported by Fesi
| Voice Phrase | Action Executed | Behavior |
|---|---|---|
| "Hey Siri, start reaction mode in Fesi" | Launches Camera Pipeline | Activates computer vision model and dims screen automatically. |
| "Hey Siri, capture my reactions with Fesi" | Begins Session | Starts rolling volatile RAM buffer and facial tracking. |
| "Hey Siri, stop recording in Fesi" | Concludes Session | Commits active highlights to your secure vault and shuts camera sensor off. |
How to Build a "Movie Night" Smart Shortcut
Because Fesi exports modular AppIntents, you can nest them inside custom Apple Shortcuts:
- Open the native Shortcuts app on your iPhone.
- Tap + to create a new Shortcut named "Movie Night".
- Add an action: Control Home → Dim living room lights to 20%.
- Add an action: Apple TV Remote → Wake TV and open Netflix.
- Add an action: Fesi → Start Reaction Mode.
Now, simply saying "Hey Siri, Movie Night" prepares your room, turns on your entertainment, and arms Fesi to capture genuine jumpscares and plot twists automatically.
