OnMessage

OnMessage is where a company's messaging strategy lives: its audiences, offerings, brand foundation, narrative, voice, and writing guidelines, all maintained as a single source of truth instead of scattered across decks and documents.

This connector gives Claude live access to that Message Library. Instead of re-explaining the brand at the start of every conversation, Claude reads the approved strategy directly: who the audience is, what the offering actually does, which words the company uses and avoids. Then it writes from it.

Anyone who connects can browse, read, and search the files their OnMessage role already lets them see. People whose role carries edit access also get write tools: creating and editing workflow files, storing documents like transcripts and research reports into the library where they become searchable, and updating structured brand strategy such as offerings, audiences, personas, and glossary terms. Every write is versioned and reversible in the app.

Access mirrors OnMessage permissions exactly and is re-checked on every request, so the connector can never reach anything the same person could not reach while signed in. Agencies managing several client brands can list the organizations they have access to and switch between them, with the active brand named on every connection.

Requires an OnMessage account on a paid plan or an active trial.
