Your assistant should work for you.¶

One assistant that works for you. Your information stays private. You decide what to share.

Unison is an open-source, local-first personal AI platform designed to return time and attention to you. UnisonOS is its Linux appliance runtime, built to run on hardware you control, work with replaceable AI models, and keep your identity, context, and decisions under your authority.

Unison works through the devices and services already in your life, including phones, computers, messaging, voice, and home devices. It coordinates those tools around your goals while preserving your familiar apps and interactions.

Unison at a Glance

Open from core to surface. Unison's core platform, appliance tooling, contracts, and experience layer are open source. It supports compatible open-weight models and replaceable external providers, each governed by its own license and privacy terms.
Local-first and model-independent. UnisonOS runs on Linux on hardware you control. It selects models according to capability, privacy, hardware fit, latency, cost, and your preferences.
Designed around your interests. Advertising, sponsored placement, engagement optimization, and commercialization of personal context have no role in Unison's decisions. Success is measured through useful outcomes, accessibility, recoverability, and time returned.
Personal by design. Each person has an independently governed assistant that can adapt to their goals, preferences, communication style, and accessibility needs. Information is shared through explicit, purpose-specific context spaces.
Available through familiar devices. You can communicate with Unison locally or through approved phone, messaging, voice, computer, and home-device channels. The authoritative assistant and personal context remain on your trusted home node.
Experiences generated in real time. Unison composes modality-aware experiences around the current intent and context. The same governed meaning can be expressed through visual, conversational, touch, speech, Braille, and future interaction modes.
Privacy and security are foundational system properties. Local authority, independently governed identities, default-deny permissions, minimized disclosure, explicit sharing, understandable confirmation, auditability, and recovery shape every capability.
A working preview with clear next steps. Integrated services, privacy controls, generated experiences, governed model routing, and a signed x86-64 software preview exist today. Realizing the full vision requires physical appliance qualification, supported model-and-hardware combinations, real-world pilots, and continued advances in capable, efficient local models.

A different incentive¶

Unison is intended to optimize for your personal objectives. Advertising, sponsored placement, engagement, and provider commercial agendas have no role in its decisions. Success is measured in useful outcomes, commitments completed, accessibility, recoverability, and time returned to you.

Your data stays under your control

Your trusted device holds the authority. External models, channels, and backup services are optional, minimized, and replaceable.

Independent assistants, intentional sharing

Each adult has an independent assistant and private data domain. You share selected context through spaces you explicitly approve.

Accessible from the start

Text, speech, visual, touch, Braille, sign, and future modalities must preserve the same meaning and control.

One assistant across daily life¶

At home, you can interact locally. Away from home, approved channels such as messaging or voice can connect you back to the authoritative node through an outbound-first gateway. A low-assurance channel can ask, draft, or notify; a sensitive action requires stronger authentication and an understandable confirmation.

Unison can coordinate the phone and apps you already enjoy as an excellent personal, administrative, and executive assistant. Your context remains under your control throughout that coordination.

What exists today¶

Area	Maturity	Meaning
Core services and shared contracts	Experimental	Integrated prototypes and automated tests cover the core architecture.
Personal and shared context	Implemented boundary	Independent identities, private data domains, and explicit shared spaces are enforced.
Trust and permissions	Implemented boundary	Disclosure, confirmation, capability authority, and revocation deny by default.
Multimodal experience	Implemented boundary	Semantic output, speech, captions, interruption, and adaptive visual preferences are tested.
Appliance release path	Public preview	A signed, digest-pinned x86-64 bundle and its verification evidence are downloadable; hardware qualification and support promotion remain open.
Remote text channel	Implemented boundary	Private Telegram long polling is tested as a low-assurance reference channel.
Encrypted backup and restore	Implemented boundary	Provider-independent backup, tamper detection, migration, and clean-device restore are tested.
High-value assistant workflows	Implemented boundary	Bounded calendar, mail, commitment, household, contact, research, and travel journeys include recovery and accessibility controls.
