AI customer service that replies in Bahasa Indonesia

By Alva Chew 6 min read Updated November 11, 2026

AeroChat replies to Indonesian-speaking customers in Bahasa Indonesia, 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 casual chat Indonesian with short forms and English shop words, calls the customer Kak or Bapak/Ibu as 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 Bahasa Indonesia

  • Casual chat Indonesian. Customers write short forms such as gak, udah, brp and ongkir (shipping cost). AeroChat reads them and answers from your products, stock and shipping rates.
  • English shop words. Ready, size, order and COD are normal in Indonesian shop chats, as in ready kak? (in stock?). AeroChat reads the mixed sentence and replies in natural Indonesian.
  • Kak and Bapak/Ibu. Online sellers address buyers as Kak, and use Bapak/Ibu for formal or business buyers. You tell AeroChat which to use, and it follows that in every reply.
  • Switching languages. A customer may switch from Indonesian to English in the same chat, or back again. AeroChat checks every message and replies in the language 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 Bahasa Indonesia. 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 Bahasa Indonesia.

Copy this into AeroChat

Reply in the language the customer writes in. When they write in Indonesian, call the customer Kak, keep the tone friendly and short, and end requests with ya. For business buyers or orders above Rp5.000.000, use Bapak/Ibu instead. Give prices in rupiah with the shipping cost and the total. If they switch to English, reply in English.

See custom instructions.

An example exchange in Bahasa Indonesia

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

Customer: Kak, sneakers putih size 39 ready? Ongkir ke Bandung brp ya
English: Hi, are the white sneakers in size 39 in stock? How much is shipping to Bandung?

AeroChat: Halo Kak, sneakers putih size 39 ready ya. Harganya Rp349.000, ongkir ke Bandung Rp18.000, jadi totalnya Rp367.000. Mau langsung diorder, Kak?
English: Hello, the white sneakers in size 39 are in stock. They’re Rp349,000, shipping to Bandung is Rp18,000, so Rp367,000 in total. Would you like to order now?

Customer: Mau kak. Bayarnya gimana?
English: Yes please. How do I pay?

AeroChat: Ini link pembayaran untuk pesanan #5512 ya, Kak. Bisa bayar pakai metode apa saja yang ada di link.
English: Here’s the payment link for order #5512. You can pay with any method on the link.

AeroChat: Pembayaran sudah kami terima, terima kasih Kak. Pesanan #5512 dikirim besok, nomor resinya nanti kami kirim di sini.
English: Payment received, thank you. Order #5512 ships tomorrow. We’ll send the tracking number here.

Customer: Btw can I exchange if the size doesn’t fit?
English: (The customer switches to English.)

AeroChat: Yes. Our policy allows a size exchange within 7 days of delivery if the shoes are unworn. Message us here and we’ll arrange it.
English: (AeroChat replies in English, from the store’s return policy.)

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 Bahasa Indonesia run on WhatsApp, Instagram, Facebook Messenger, Telegram, your website chat and email. On Shopee, Lazada and TikTok Shop buyer chat, AeroChat answers in Bahasa Indonesia 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 Indonesia, AeroChat sends payment links through Midtrans, DOKU and Xendit and books and tracks deliveries with AnterAja.

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 Bahasa Indonesia. With agent auto-translation, incoming messages are shown in the agent’s language and replies go back to the customer in Bahasa Indonesia, with the original message kept beside the translation. Auto-translation is on the Advanced plan. See pricing.
