The question takes a minute.Getting back into focus takes longer.

A customer needs a hand. You leave what you’re building, find the right help article, and write the answer. Then the same question arrives in another conversation.

“How do I export a report?”
“Where can I change my plan?”
“Can I talk to someone?”

Give everyday questions a good answer. Save your attention for the ones that need you.

A few things to know

Read all FAQs

Where do I start?

Sign in with Google, create an agent, then add your product docs as files, pages, a website or text. Ask it questions in the preview, connect LINE or the website Widget, and publish.

Can I control what the AI says?

Yes. An agent can answer directly, hand over to a person when needed, or only write drafts your team approves. You set its rules, take over in the Inbox, and hand the conversation back to the AI when you're done.

Which channels are supported?

LINE Official Accounts and the website Widget are live, Messenger and Instagram are in early access, and WhatsApp is not available yet. Every plan includes all available channels.

How do billing and the trial work?

Every plan includes a monthly number of conversations; a one-to-one conversation counts as new after 24 hours without a message. Starter comes with a 14-day free trial.
