The voice-first agentthat runs your computer

Sentris lives in your tray as an ambient overlay — listens on demand, plans, verifies, and takes real action across your desktop and logged-in Chrome session. No dashboards. Just intent.

How it works

From a whisper to verified action

Sentris is not a chat box. It's a runtime — a bounded plan-and-execute harness with deterministic verification, guardrails, and memory.

01

Speak intent

Tap the tray pill or say the wake word. Sentris captures intent locally and turns voice into a structured plan.

02

Plan & execute

A plan-and-execute harness drafts steps, dispatches them to computer, browser, and file agents, and replans on failure within bounded retries.

03

Verify deterministically

Every step is verified against expected post-conditions. Side-effectful actions surface a confirmation in the overlay before they run.

04

Act on your behalf

Sentris drives your actual desktop and your already logged-in Chrome session — no scraped credentials, no headless ghosts.

Agents

Three thin agents. One harness.

No monolith. Each agent is intentionally narrow, observable, and replaceable. The harness orchestrates them with bounded replan and deterministic verification.

Desktop control

Computer agent

Drives native macOS apps via accessibility APIs and scripted UI. Opens, types, clicks, reads — without you handing over your screen to a stranger in the cloud.

  • AX tree navigation
  • Keyboard & mouse
  • Window orchestration
  • App scripting
Chrome bridge

Browser agent

A required Chrome extension lets Sentris act inside your already logged-in session. Real cookies, real auth, real DOM — no brittle headless replays.

  • Logged-in sessions
  • DOM-aware actions
  • Tab orchestration
  • Per-domain scopes
Local I/O

File agent

Reads, writes, and reasons over local files inside scoped directories. Diffs are previewed in the detail panel before anything touches disk.

  • Sandboxed paths
  • Diff previews
  • Format-aware edits
  • Atomic writes
Security & guardrails

Trust is a runtime property.

Sentris treats safety as something the harness enforces every step, not a policy document on a shelf.

Local-first by default

Audio is captured on-device. Sessions, cookies, and file content never leave your machine unless a step explicitly requires it.

Visible runtime

Browser trust, orchestrator readiness, permissions, and pending confirmations are always surfaced in the overlay — never hidden.

Bounded replan

Failures don't spiral. The harness replans within hard step budgets and aborts safely with a human-readable trace.

Deterministic verification

Every action declares a post-condition. No post-condition, no execution. No hallucinated success states.

Voice demo

One sentence. Five real actions.

Watch the harness decompose a casual instruction into a verified plan executed by the right agents — with a confirmation gate before anything irreversible.
