You can share your presentation with specific people, your Teamspace, or anyone with a public viewing link. Click Share in the top toolbar to choose who can access it.
Inviting specific people
Enter one or more email addresses (comma-separated).
Choose their permission level: can view, can comment, can edit, or can edit & share.
Click Add.
You can change or remove anyone's access at any time from the same panel. You can even choose to give them no access at all, which means they can no longer see the presentation.
Controlling broader access
Below the invite field, you can switch from "Only Invited People have access" to opening it up to your whole Teamspace, which has its own separate permission level.
To let someone view without a Napkin account, enable public link access in the Share panel and use Copy Link. Anyone with that public link can view the presentation.
Quick actions from the share panel
The share panel also has quick buttons for Export PDF, Export all visuals, and Copy Link. You can use these without leaving the share panel.
