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.
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/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
Paste your website URL and OneChat drafts your agent from your real content. Connect a channel, review a few test answers, and you’re live — today.

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, regardless of how many messages are exchanged in it. Your plan includes 100 conversations per 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 100 conversations?
You can add more conversations whenever you need them, 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.
