Description
Hecate is an AI you can voice and video call from Signal iOS and Android. This works by installing Signal into an Android emulator and controlling the virtual camera and microphone. Tinfoil.sh is used for private inference.

Could you build this?
Partial Connecting an LLM to audio/video APIs is straightforward, but orchestrating real-time audio and video streams through a headless Android emulator running Signal requires complex low-level OS plumbing.
What it would actually take: The architecture involves an Android emulator (such as Cuttlefish or Android SDK emulator) connected to virtual media loops via v4l2loopback and PulseAudio/ALSA virtual sinks. The difficult part is synchronizing low-latency bi-directional WebRTC/RTP audio-video feeds with an AI voice agent while automating Signal UI lifecycle events via ADB. This requires specialized Linux audio/video subsystem and Android emulation systems engineering.

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
