ThinkVoice App Combines Grok and BCI to Help Non-Verbal Users Communicate
Daniel_Farinax · x · 2026-08-09
ThinkVoice is an early-access assistive app designed to help individuals with complex speech needs (such as ALS or post-stroke) or those needing silent communication.
Core Features & Workflow:
- Intention Sensing: Uses EEG/IMU signals from the Muse 2 headband or on-device ARKit via the iPhone's front camera to translate blinks and nods into commands.
- Cloned Voice & Interaction: The phone listens to the room, generates reply chips, and speaks the selected line using the user's cloned voice.
- Grok Realtime Voice: Integrates xAI’s realtime voice model on iPhone and Apple Watch, allowing one-tap access to an AI assistant with Apple Health metrics as context.
The app is currently available via an invite-only TestFlight and is not yet on the public App Store.
