Early Access — macOS

A fixed reference frame
amid information chaos

Sidereal is a local-first AI operations platform for macOS. Your agents run dispatch, triage, and synthesis while you focus on what matters — or while you sleep. Private, auditable, and entirely yours.

macOS 15.0+ · Obsidian · No cloud required

Autonomous dispatch

Skills run on a schedule while your machine is unattended. Email triage at 7 AM, digest at noon, inbox at day's end — hands-free.

Vault-native memory

Every AI action writes human-readable Markdown. Your vault is the source of truth — auditable, correctable, yours.

Fleet coordination

Sidereal runs across your machines. Dispatch locks prevent duplicate work. Tailscale provides the network when not on LAN — zero custom infrastructure.

Privacy by design

Your data never leaves your machine.
Unless you tell it to.

Multi-axis provider routing lets you send sensitive content only to local models. Every decision is logged as a human-readable Markdown note in your vault — no opaque databases, no vendor lock-in.
