How seats work - Plain Docs

Plain has 2 types of seat: member seats and viewer seats. You pay for member seats, which let users reply to customers. Viewer seats are free and unlimited on every plan.

Member seats

Member seats are for the users who reply to customers. Your plan sets the price of each member seat and how many you can have. A user with the Owner, Admin, or Support role uses a member seat.

Viewer seats

Viewer seats are for users who need customer context but don’t reply to customers, such as people in product and engineering. A user with the Viewer role uses a viewer seat. Viewers can read threads and customer context across your workspace, but they can’t:

Reply to customers
Create a broadcast or change a broadcast’s target
Assign a thread to themselves by reacting to it in Slack

Viewers can use Sidekick by default. A workspace Admin or Owner can turn off Sidekick access for Viewers in Sidekick → Settings. A viewer seat is free, but Sidekick sessions started by a Viewer use credits from your workspace’s allowance, the same as any other session.
