Shared Agent Brain

Give your AI agents a shared private brain across all your machines.

The fleet 02 / 10

Five agents. Five machines. One brain.

Instead of every agent starting from scratch, your fleet compounds context through one private machine network.

Durable memory 03 / 10

Agents remember what matters — as plain markdown.

Memories live as human-readable markdown in your Obsidian vault, sync across trusted machines through Hivemind Sync, and are retrieved through a local API — never a hosted memory service.

Provenance 04 / 10

Every memory knows where it came from.

Which agent wrote itagentName · agentId
Which runtime wrote itruntime
Which machine wrote itmachineName · machineId
Which project / sessionproject · sessionId
Tailnet provenancetailnetId · name · dnsName
Not just what happened —
but which agent, on which machine, inside which part of your private Hivemind.
Memory with identity baked in.
Local-first 05 / 10

Local recall. Fleet-wide memory.

Each trusted machine keeps its own local copy of the brain. Agents get fast local recall while shared memory propagates across the fleet.

Your vault STAYS YOURS

The memory layer never leaves your vault.

Markdown notes, retrieval index, and proof receipts all live in your private shared brain — no hosted vector database.

First indexed reads were effectively as fast as cached reads. The private local index keeps rich, typed recall in milliseconds — versus hundreds of milliseconds scanning raw markdown.

10 / 10
A shared cross-machine brain for your private agent fleet — typed, provenance-aware memory that syncs across trusted machines, recalls locally in milliseconds, and proves itself without exposing the body.
