A branch is a folder, with everything inside it, or a single note. You give it to someone by their email address, read-only or read-write. It appears in their tree, and their AI reads it too.
Four, from the dashboard.
From the tree on the left, open what you want to share. If it is a folder, the share covers everything inside it, including the notes you put there tomorrow.
Top right, in the header, there is Share (on a phone it sits in the ⋯ menu). The panel opens with the list of who already has access.
Type the person’s email and choose Can read or Can write. Press Share: they get an email with the link to come in. If they do not have an account yet, they create one with that same address, free.
In their tree, under Received, the branch appears with your name next to it. When they ask their AI about the client, the AI finds your notes alongside their own. To take access back, open Share again and remove the person: from that moment they see nothing, and neither does their AI.
What people usually ask after their first share.
Why sharing is the heart of the product is explained on the page in a team.
The free plan includes one. Whoever receives it signs in with their email, and their AI reads it straight away.
