You can create as many workspaces as you want and each have their own users, security, billing and other administrative options.
Here is an animated screenshot to walk you through hovering over "Workspaces", and then clicking "Create" on the https://app.konch.ai/settings page.
When you have several workspaces, you can switch between them in the menu. Remember, each workspace has its own set of users, owners, and payment plans. If you have more than one Workspace, make sure you are in the expected Workspace when uploading or adjusting settings.
