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.

You already wrote the answer. Let your docs do the talking.

Your getting-started guide. Your help center. The explanation you’ve typed more times than you can count.

Add your documents, individual web pages, or your whole website. Replai uses that knowledge to answer customers in your product’s own context.

How knowledge sources work

An answer when it’s simple. A person when it matters.

Let Replai answer directly, or review its drafts before they go out. Set the tone and the boundaries that fit your team.

Pick up where the conversation left off.

When a customer needs you, take over in the same inbox, with the conversation right there.

Try the conversation. Change the tone, review a draft, or ask for a human.

A few things to know

All questions

How do I get started?

Sign in with Google, create an Agent, and add your product docs as files, web pages, a website or text. Try questions in the preview, connect LINE or the website widget, then publish.

Can I control what the AI sends?

Yes. The Agent can answer directly and hand off when needed, or only write drafts that your team approves. Set rules, take over in the inbox, and return the conversation to the AI when you are done.

Which channels are available?

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?

Each plan includes a monthly number of conversations; a one-to-one conversation starts over after 24 hours without messages. Starter includes a 14-day free trial.
