What is Aleph?

Aleph is a self-hosted, fully local voice assistant. The aleph runtime ships as a single binary that turns a wake phrase into a spoken answer entirely on hardware you control — no cloud services, no accounts, no telemetry.

The one-step promise

There is exactly one manual step: launching aleph. Everything else — downloading models, provisioning the ML runtime, repairing broken state — is the program's job to figure out at runtime.

Features

• Full local voice loop: wake → STT → LLM → TTS playback
• Streaming speech-to-text partials via Parakeet
• Streaming LLM output via in-process llama.cpp (Gemma GGUF default)
• Streaming text-to-speech with bundled reference voices
• OS-local tools and MCP servers exposed to the LLM
• Satellites for desktop, Android, and ESP32-S3 hardware

Who is it for?

People who want to self-host an Alexa without becoming sysadmins.
