AI customer service that replies in Thai

By Alva Chew 6 min read Updated November 11, 2026

AeroChat replies to Thai-speaking customers in Thai, on every channel you sell on, and finishes the job in the chat: it answers from your products and orders, sends the payment link and confirms the order. It reads Thai mixed with English product words, ends its replies with the polite particle you choose, and follows the customer if they switch to English mid-chat. There is no language menu. The customer writes, and AeroChat answers in the same language.

How your customers write in Thai

  • Thai mixed with English. Customers write product names, sizes and colors in English inside a Thai sentence, such as ไซส์ M or สี cream. AeroChat reads the whole message and matches it to your products.
  • Polite particles. Thai shop chats end sentences with ค่ะ or ครับ, and call the customer คุณ. You choose which particle your store uses, and AeroChat uses it in every reply.
  • Short, casual messages. Customers often send a few words, such as มีไหมคะ (do you have it?) or ส่งกี่วัน (how many days to ship?). AeroChat answers the question behind them from your store data.
  • Switching languages. A customer may start in Thai and switch to English, or the other way round. AeroChat checks the language of every message and replies in the one the customer is using now.

What AeroChat does with each message

  1. Detects the language. AeroChat identifies the language from the customer’s first message, including mixed-language messages, without asking them to choose.
  2. Replies in Thai. It answers from your store data, such as products, stock, shipping rates and orders, in the tone you set.
  3. Checks again on every message. If the customer switches language partway through, AeroChat follows them.
  4. Falls back when a message is too short. For a reply such as OK or a single emoji, AeroChat uses the default language you set.
  5. Transcribes voice notes. On WhatsApp, voice notes are transcribed automatically and answered like typed messages.

See multilingual chat and WhatsApp voice notes.

Set the tone in your own words

You tell AeroChat how your store talks, in your own words and in any language. It follows those instructions in every reply. Here is an example for a store whose customers write in Thai.

Copy this into AeroChat

Reply in the language the customer writes in. When they write in Thai, end sentences with ค่ะ, call the customer คุณ followed by their first name, and keep replies short. Use product names as they appear in our store. If they switch to English, reply in English. Never promise a delivery date the courier hasn’t given.

See custom instructions.

An example exchange in Thai

A customer messages the store on WhatsApp. The English under each line is a gloss.

Customer: สวัสดีค่ะ เดรสลินินสี cream ไซส์ M ยังมีไหมคะ
English: Hello, is the linen dress in cream, size M, still available?

AeroChat: สวัสดีค่ะ เดรสลินินสีครีม ไซส์ M ยังมีสินค้าค่ะ ราคา 1,290 บาท ค่าส่ง 50 บาท รวม 1,340 บาทค่ะ รับเลยไหมคะ
English: Hello, the cream linen dress in size M is in stock. It’s 1,290 baht plus 50 baht delivery, 1,340 baht in total. Would you like it?

Customer: เอาค่ะ ok จ่ายยังไงคะ
English: Yes please, OK, how do I pay?

AeroChat: นี่คือลิงก์ชำระเงินสำหรับออเดอร์ #4821 ค่ะ ชำระได้ทุกช่องทางที่อยู่ในลิงก์เลยนะคะ
English: Here’s the payment link for order #4821. You can pay with any option on the link.

AeroChat: ได้รับชำระเงินแล้วค่ะ ขอบคุณค่ะ ออเดอร์ #4821 ยืนยันแล้ว จัดส่งพรุ่งนี้ และจะส่งเลขพัสดุให้ในแชทนี้ค่ะ
English: Payment received, thank you. Order #4821 is confirmed and ships tomorrow. We’ll send the tracking number in this chat.

Customer: Can I change the delivery address to my office?
English: (The customer switches to English.)

AeroChat: Yes. Please send the office address with the postal code and I’ll update order #4821 before it ships.
English: (AeroChat replies in English.)

The customer never types “paid”. AeroChat detects the payment from the gateway and confirms the order in the same chat.

Where it runs

The same replies in Thai run on WhatsApp, Instagram, Facebook Messenger, Telegram, your website chat and email. On Shopee, Lazada and TikTok Shop buyer chat, AeroChat answers in Thai from the product details, policies and order information the marketplace shares, and orders, payment and shipping stay in the marketplace.

Your store connects from the dashboard: Shopify, WooCommerce or Wix. If you sell in Thailand, AeroChat sends payment links through Omise and 2C2P and books and tracks deliveries with Flash Express.

When your team takes over

AeroChat finishes the job in the chat, and hands over to a person only as a safety net, such as a refund above the limit you set. When that happens, your team doesn’t need to read Thai. With agent auto-translation, incoming messages are shown in the agent’s language and replies go back to the customer in Thai, with the original message kept beside the translation. Auto-translation is on the Advanced plan. See pricing.

Questions

Do I need to set up Thai separately?

No. AeroChat detects Thai from the customer’s message and replies in it. You can add instructions for tone and forms of address, and set a default language for messages too short to detect.

What if a customer mixes Thai and English?

AeroChat reads the whole mixed message and replies naturally. You can say in your instructions which language to use for mixed messages, for example Thai.

Can my products and policies stay in English?

Yes. AeroChat answers in Thai from the product details and policies you already have. You don’t need a second copy of your store in Thai.

Can my team handle Thai chats if they don’t speak it?

Yes, with agent auto-translation on the Advanced plan. Your team reads and writes in their own language, and the customer receives Thai.
