What they look like

Both run on your own Mac. Maius v2 is the deck for a whole fleet; Natto is one agent, entirely local.

The Natto window in cream and yellow: a single agent called Natto, its reply filling the page, and a column of widgets on the right
Natto — one agent, thinking on your own Mac
The Maius v2 deck: a list of agents down the left, a conversation in the middle, and the same widget column on the right
Maius v2 — your fleet, and everything they are doing
