Why OneChat

Support that feels like your best teammate

Built for shops and services whose customers live in messaging apps — not in email tickets or website widgets.

Every channel, one brain

Train OneChat once and it answers everywhere — LINE, WhatsApp, Instagram, Telegram, KakaoTalk, Shopify and Crisp. Same knowledge, same tone, no copy-pasting between tools.

55+ languages, automatic

OneChat detects the language your customer writes in and replies natively — Japanese, English, Korean, Thai, Spanish and 50 more. No configuration needed.

Understands voice notes

Customers on LINE and WhatsApp love voice messages. OneChat transcribes and answers them like any other message — no “sorry, I can only read text.”

Human handoff to Slack

When a conversation needs a human, OneChat escalates to your Slack with full context. You jump in exactly where the AI left off — customers never repeat themselves.

No surprise bills. Ever.

A flat $29.99/month with hard spending caps built in — not $0.99 per resolution that snowballs into a four-figure invoice. You always know what you’ll pay.

Live in 15 minutes

FAQ

Frequently asked questions

Which platforms does OneChat support?

LINE, WhatsApp, Telegram, Instagram, KakaoTalk, Shopify and Crisp plugins — all included in every plan. You can connect one channel or all of them at no extra cost.

What counts as a conversation?

A conversation is one customer chat session handled by the AI. Your plan includes a monthly usage allowance that covers about 200 conversations — our customers’ average. Short chats use a little less, long ones a little more, and anything unused rolls over to the next month.

Do you charge per user or per seat?

No. Every plan includes unlimited team members at no extra cost. Invite your whole team — pricing is based on conversations, never on seats.

What happens when I go over my included conversations?

Extra usage is about $0.15 per conversation, protected by a hard spending cap you control — so your bill can never run away from you. No per-resolution fees, ever.

Do I need to add a chat widget to my website?

No. OneChat works inside the messaging apps your customers already use. There is nothing new for customers to install or learn — it plugs into your existing channels.

What languages can it speak?

OneChat automatically detects and replies in more than 55 languages, including Japanese, English, Korean, Chinese, Thai, Vietnamese, Spanish, French and German.

Can it hand off to a human?

Yes. When the AI is unsure, or the customer asks for a person, OneChat escalates the conversation to your team on Slack with the full chat history attached.
