Smart home, finances, scheduling, voice, communications — most people stitch these together across a dozen apps and accounts. Syntaur consolidates them under one consistent interface, with a persistent memory layer so the AI actually remembers you.

One binary, signed with Sigstore cosign. Linux · macOS · Windows. Promoted from the active development branch on a weekly cadence.

Pure-Rust gateway for the household  ·  multi-protocol (Matter, Thread, BLE, MQTT, vendor APIs), no vendor cloud dependencies

Tax & finance  ·  year-round picture with pass-through partner filing

Scheduler  ·  calendar, todos, habits in one coherent view

Voice  ·  local STT and AI assistance via Bluetooth pendant or phone

Privacy  ·  per-device policy, DNS sinkhole, network segmentation

Engine  ·  the pure-Rust runtime that everything else builds on

Local-first.  Your home runs on your gateway, not our cloud.

Pure Rust.  Every service we own is Rust.

Pass-through partnerships.  Third-party services routed at cost, no markup.

Open by design.  Standards (Matter, MQTT, IMAP) over proprietary lock-in.

One identity.  Sign in once, everywhere.
