Privacy

Your agent history should not require another cloud.

Masthead is built around local-first collection and indexing. The boundary depends on the sources, enrichment provider, and connected agents you configure.

Operating modes

Choose how session context moves.

Fully local

local storage
local enrichment
local model

Session records stay on the machine when every configured part is local.

Bring your own model

local storage
user-configured provider

Only enrichment requests you configure are sent to the provider you choose.

Connected agent retrieval

Masthead stays local
retrieved context is passed to the agent you choose

MCP retrieval uses the local session library, then shares selected context with the agent you choose.

Boundary note

Local-first does not mean every configuration is offline.

Masthead can keep storage and indexing on your machine. If you configure a hosted model provider or connect an agent that receives retrieved context, those configured systems may receive the selected data needed for that operation.
