AI Assistants

An Assistant is what answers your visitors. It follows its Instructions, answers with the model you choose, and searches its Knowledge Base for what to say. You build and test it on the Platform, and it answers visitors once it is in deployment, on a website, in Reverb 2.0 help, or both.

What an Assistant is made of

Every setting is on the Assistant's Configure tab except the installs.

Build, test, install

Open an Assistant from AI Assistants to work on it in three tabs.

Tab

What you do there

Configure

Change its settings.

Preview

Chat with it as you configure it. See Test an Assistant in Preview.

Install

Copy the script tag for a website or the Assistant ID for Reverb 2.0 help, set the Embedded Assistant's colors and language, and see what still has to be done before it answers visitors. See Installs.

In a wide window, Configure and Preview sit side by side, and Install is in the top bar. The header shows the Assistant ID with a copy button, the model, and whether the Assistant is In Deployment or Not deployed.

Saving

Changes on the Configure tab, Knowledge Base uploads and removals included, wait for Save Changes in the top bar. The button appears once something has changed, and Up to date takes its place after the save. Leaving the page with unsaved changes asks whether to Leave or Stay.

Three things save apart from it: the avatar and the In Deployment switch save as soon as you change them, and the Install tab's appearance settings have their own Save button.

One Assistant, both installs

One Assistant can answer on your website as the Embedded Assistant and in Reverb 2.0 help as the Reverb Assistant at the same time. Both installs use its settings, its Knowledge Base and its one In Deployment switch, and both find it by its Assistant ID.

An Assistant has one model. To run a light model on your website and a larger one in your help, create two Assistants.

Who can work on Assistants

Everyone in the organization, whatever their role, can create, configure, test, deploy and delete its Assistants. AI Assistants lists the Assistants of the organization you are working in. What they spend is paid from the organization's credits, which only the owner and billing managers manage. See Roles and permissions.
