Customer messages in Hindi and regional languages with AI

A customer who writes to you in Hindi, Marathi or Tamil is telling you which language they are comfortable in. Replying in English makes them work harder. AI assistants can now write usable drafts in Hindi and in many other Indian languages. The quality varies by language and by tool, so the method matters.

Decide four things first

1. Language. Hindi, Marathi, Gujarati, Tamil, Bengali and so on.
2. Script. The language's own script, or English letters. Many customers type Hindi in English letters on WhatsApp ("Aapka order kal dispatch hoga"). Match what your customers do.
3. Formality. Respectful forms for customers, for example "aap", never "tum" or "tu".
4. Mix. In everyday business messages, common English words stay in English: order, delivery, payment, booking, discount. A message in pure, bookish language sounds strange.

The prompt

Write this customer message in [language], in [script]. Use the respectful form of address. Write the way a polite shopkeeper in [city or region] would speak, not a word-for-word translation. Keep these words in English: [order, delivery, payment, product names]. Keep all numbers, dates, prices and names exactly as given. Under [number] words. Message: "[your English or rough message]"

If you are writing from rough notes instead of translating, say: "Write a message that says the following points."

Example: one message, three forms

A made-up courier agent, used only to show the difference.

English: "Your parcel has reached our office. Please collect it between 10 am and 6 pm, and bring an ID proof."

Hindi in English letters: "Aapka parcel hamare office pahunch gaya hai. Kripya ise subah 10 baje se shaam 6 baje ke beech collect kar lein, aur ek ID proof saath layein."

Hindi in its own script: the same sentence, written in Devanagari. Ask the AI for it, and have a Hindi reader check the spelling before you use it.

Reply in the customer's style

Paste the customer's message (without their name or number) and ask:

Reply in the same language and the same script as this customer's message, with the same level of formality. The answer to give: [your answer in any language].

This is the quickest way to get the mix right, because the customer has already shown you.

Always check with a native speaker

AI makes mistakes in Indian languages that it would not make in English:

• words that are correct but too formal or old-fashioned
• the wrong gender or respect form
• mixed scripts or spelling errors
• a literal translation of an English phrase that means nothing in the other language

For one-to-one replies, the team member who speaks the language reads before sending. For anything sent to many people, such as a broadcast, a poster or a festival greeting, a native speaker must check every word. A mistake seen by five hundred customers is expensive.

Build a small phrase bank

Once a native speaker has approved a message, save it. After a month you will have approved versions of your twenty most common messages in each language you need: order confirmation, dispatch, payment reminder, thank you, festival greeting, apology. Reuse them instead of generating new ones each time. See How to build a WhatsApp reply library.

Things that must stay exact

• prices, quantities, dates and times
• product names and model numbers
• addresses and phone numbers
• terms and conditions

Tell the AI to keep them unchanged, and compare them with the original before sending.

Keep English where the law or precision needs it

Invoices, contracts, warranty terms and policy pages are usually best kept in English, or in the language of your official documents, with a short explanation in the customer's language if needed. Do not rely on an AI translation for anything with legal weight.

Voice messages

Many customers prefer to send and receive voice notes. AI tools can turn a voice note into text, which helps you record what was asked. For replies, a short voice note recorded by your own team is often better received than any text.

Festivals and greetings

Regional greetings differ. A message for Pongal, Onam, Baisakhi or Eid should use the greeting people in that community actually use. Ask the AI, then check with someone from that community. Do not send the same translated greeting to everyone.

Mistakes to avoid

• Translating word for word. Ask for natural writing.
• Changing the customer's language. If they write in Hinglish, reply in Hinglish.
• Sending unchecked text to a large group.
• Assuming all tools are equal. Test your languages: see How to choose an AI assistant for your business.
