Each plan includes one user, and extra seats cost $40 to $80 a month.There's one plan and it's free. Microsoft says it's free forever with no traffic limits. Install the tag through Shopify, WordPress or Google Tag Manager and it starts recording within minutes.Start on Starter to see where you stand in AI answers. Growth is the plan for teams who will act on the findings each month, because that is where sentiment and suggested fixes come in.
