Your voice stays yours.

Microphone audio NEVER leaves your device. Only approved text tool requests (like asking for the weather) may leave, and every single action is recorded in a local, transparent privacy ledger.

No Audio Uploads

Speech-to-text happens entirely on-device. Your raw voice is never sent to the cloud.

Approved Tools Only

Only specific, user-approved text requests (like fetching weather data) can access the internet.

Privacy Ledger

Complete transparency. Review a local log of every action and tool request Trusty makes.

Comparisons

Why Trusty?

See how Trusty stacks up against the competition.

Vs. Big Tech

Big tech assistants send your raw voice audio to giant cloud servers to be processed and recorded. Trusty processes all audio on-device. No cloud accounts, no subscriptions, no surveillance.

Vs. Traditional OSS

Rhasspy, HA Assist

Most offline assistants match your voice against rigid, pre-trained intent templates. You have to speak exact phrases. They lack the conversational intelligence of modern AI.

The Trusty Way

Powered by Reasoning

Trusty uses Gemma 4 as the actual orchestrator. It uses reasoning to pick tools, synthesize arguments, and understand natural language. The LLM is the brain of the home, not just a chat layer.

Features

Built block by block.

Everything you need, snapping together — running locally.

Local Gemma 4

The brain and orchestrator, running efficiently via llama.cpp on your local hardware.

Fast STT & TTS

Powered by Moonshine ONNX and Kokoro ONNX for near-instant voice recognition and natural speech synthesis.

Smart Home Control

Seamlessly controls LG webOS TVs, Roborock vacuums, and more via Home Assistant integration.

Local Memory

Remembers names, preferences, and locations locally without ever sending your personal data away.

Eyes UI

A friendly, animated local web interface that gives your assistant personality and visual feedback.

Offline Mode

Hard-blocks internet tools when you want absolute grid-down privacy and complete isolation.
