How Dagny works

Multiplayer.

You don't each get your own Dagny. The team gets one, and that's the feature: brief it once, and it shows up prepared for everybody.

Shared from day one

One brain. Facts, files, and everything Dagny has learned belong to the workspace. A correction made in Slack holds on the web, by text, everywhere.
One set of tools. Connectors are wired up once, then anyone's question can draw on them. Nobody re-connects Stripe at their own desk.
One rhythm. Automations, reports, and scheduled work run for the team, not per person. Set the Monday summary up once and everyone reads it.

Who sees which conversations

Shared brain doesn't mean shared everything. Conversations follow the room they happened in:

Team chats are the team's. New conversations in the workspace are shared threads, like a Slack channel: everyone sees them in their sidebar, anyone can jump in, and Dagny reads the room — answering when addressed, staying out of the way when two teammates are talking to each other. Conversations started before shared threads arrived stay private to whoever started them.
Your personal space is yours. Chats in your personal space never appear in anyone else's sidebar.
Texts are yours. An iMessage thread with Dagny is between you and Dagny.
Open Slack channels are the team's. When Dagny answers in a public channel, that conversation shows up in the workspace for everyone, same as the channel itself.
Private stays in Slack. Private channels, group DMs, and direct messages never appear in the workspace, for anyone. Those conversations live where they happened, and Dagny takes no notes there. When it can't tell whether a room is private, it errs on the side of keeping it out of view.

Three roles, no ceremony

Viewers ask. Full conversational access to Dagny and everything it knows.
Editors teach. Everything viewers do, plus feeding Dagny: facts, files, connectors, automations.
Owners steer. Everything editors do, plus members, roles, billing, and the switches that decide where Dagny is allowed to speak.

Inviting someone takes an email address and a role, under Settings. People who only ever talk to Dagny in Slack don't need a seat at all; being in the channel is enough.

Good to know

There's no personal notebook inside a workspace: whatever Dagny is taught becomes team knowledge, and what's said in private isn't kept at all. If part of your work needs a genuinely separate Dagny, a separate brain and separate tools, give it its own workspace and switch between them from the sidebar.
