Quick Start

OneChat is one AI support agent for every chat channel your customers already use — LINE, WhatsApp, Instagram, Telegram, KakaoTalk, Shopify and Crisp. You train it once, and it answers everywhere, 24/7, in more than 55 languages.

Most teams go live in about 15 minutes. Here's the whole flow.

1. Create your agent from your website​

  1. Sign up at onechat.app.
  2. Paste your website URL when prompted.
  3. OneChat reads your site, FAQs and policies, then drafts your support agent automatically.
tip

The better your website answers a question, the better your agent will answer it. If a policy only exists in your head, add it to the agent's instructions in the next step.

2. Refine the instructions​

Open Agent → Instructions to review what OneChat drafted. This is your agent's system prompt — plain language, no code or flowcharts:

  • Describe your tone ("friendly, concise, no emoji").
  • Add policies the website doesn't cover (shipping cutoffs, refund exceptions, business hours).
  • Tell it what it should not do ("never promise a delivery date; offer to check with the team instead").

See Your AI agent for a deeper guide to writing good instructions.

3. Connect a channel​

Head to Channels and connect where your customers already are. Each connection is one click plus a short platform-specific authorization:

All channels are included in every plan — connect one or all of them at no extra cost.

4. Test it​

Send a few real customer questions from your own account on the connected channel. Check the answers in the OneChat dashboard, and adjust the instructions until you're happy.

5. Go live and relax​

That's it. OneChat now answers around the clock and escalates to your team on Slack whenever a human should take over. You can watch every conversation live from the dashboard.

What's included​

  • 100 conversations per month are included in every plan; additional conversations are $0.20 each, protected by a hard spending cap you control.
  • Unlimited team members — pricing is based on conversations, never on seats.
  • See Plans & billing for details.
