1. Introduction
Jantra World is a WhatsApp AI assistant for users beyond India - the international sibling of Jantra Bot. It lives inside a WhatsApp thread and answers in the language you write in. No app to install, no login, no new account.
Save the number at world.jantrikai.com and send a message to get started.
Who is it for?
International users
Anyone outside India who wants a capable AI assistant without downloading yet another app - Jantra World lives inside the WhatsApp thread you already have open.
Multilingual chatters
People who write in more than one language a day. Reply in whichever language fits and Jantra World follows along without settings.

Travellers & expats
Translate quick messages, look up meanings, get a short cultural explanation - without switching between apps or tabs.

Example asks

|---|---|
| Translate "How much does this cost?" to Thai. | Returns the phrase plus a short romanised guide. |

6. Voice Notes
Send a WhatsApp voice note in the language you speak. Jantra World transcribes, answers, and where supported can send an audio reply back - useful when your hands are busy or a keyboard is slow.
Speak your language
Voice input is treated as first-class. No need to type on a small keyboard.
Text or audio back
Replies default to text - ask for a voice reply where available.
Cross-language
Speak in one language, ask for a reply in another - handy for translation.
7. Languages
Jantra World is tuned for international users. English is the anchor; other languages are added as we ship into new regions. Just start writing in the language you prefer - no configuration needed.
Currently supported

9. Tips & Tricks
Write like you would to a friend
Jantra World is tuned for casual conversation - short questions, follow-ups, and code-mixed replies all work.
Use voice notes for long inputs
When you have a lot to say, a voice note is faster than typing on a phone keyboard.
Switch languages naturally
You do not need to announce a language change. Just reply in the language you want and Jantra World will match.
Ask for the format you want
Say "in three bullets" or "as a short paragraph" - Jantra World will follow the instruction.
Reset when the thread drifts
If a long conversation wanders off-topic, send /reset to start fresh.
Save the contact
Once the number is in your contacts, WhatsApp will show it in search - much faster than reopening a link.
