Early Access — macOS, iOS

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+ · Apple Silicon · No cloud required

Agent workflows

Define multi-step workflows as Packs — composable graphs that chain reasoning, extraction, and synthesis. Run them on a schedule, trigger them from events, or launch them on demand.

Vault-native memory

Every agent action writes human-readable Markdown back to your vault. Decisions are auditable, correctable, and yours — no opaque databases.

Fleet coordination

Sidereal runs across your machines. Dispatch leases prevent duplicate work. Bonjour on LAN, Tailscale over the internet — 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.
