1. Introduction
Jantra Bot is a multilingual AI assistant that lives entirely inside WhatsApp - the messaging app you already use every day. There are no downloads, no signups, no new apps to learn. Just open a chat with the bot and start asking questions in any of 10 supported languages.
Built by Coding Ryder and powered by Google Gemini and Sarvam AI, Jantra Bot combines cutting-edge AI with deep support for Indian languages - including Assamese, Kannada, Hindi, Bengali, Tamil, Odia, Malayalam, and the beloved romanised hybrids Kanglish and Hinglish.

6. Voice Support
Jantra Bot understands voice notes. No typing needed - just hold the microphone button in WhatsApp and speak naturally. The bot will transcribe your voice and respond in your chosen language.
How it works
- 1
Record
Record a voice note in WhatsApp as you normally would.
- 2
Receive & route
Jantra Bot receives the audio and sends it to Sarvam AI - a speech-to-text engine built specifically for Indian languages.
- 3
Understand
The transcription is passed to Gemini AI, which generates a response in your set language.
- 4
Reply
You receive the response as a text message in your chosen language, ready to read or copy.
Voice technology - Sarvam AI
Jantra Bot uses Sarvam AI (sarvam.ai) for voice transcription - an Indian startup whose models are trained natively on Indian languages including Assamese, Kannada, Hindi, Bengali, and Tamil. This makes it significantly more accurate for Indian accents and regional speech patterns than generic speech engines.
Quiet environment
Record in a quiet room for best accuracy.
Speak naturally
Don't slow down unnaturally - speak as you normally would.
Good connection
Ensure your internet connection is stable when sending audio.
Any length
Short or long - there's no strict time limit on voice notes.

9. Tips & Tricks
Switch modes mid-conversation
You can change mode at any point without losing context. Ask your last question in Assistant mode, then switch to Dictionary to look up a word from that answer.
Use voice for long queries
Instead of typing a long question, record a voice note. It's faster, and the AI handles natural spoken language better than broken typed text.
Mix languages freely
You don't have to type in your set language. Ask in English even when your language is set to Kannada - the bot will reply in Kannada regardless.
Follow-up questions
"Tell me more", "Give me an example", "Explain that differently" - the bot remembers your recent conversation in Assistant mode.
Photograph text for translation
Take a photo of a sign, menu, or document and Jantra Bot will describe it including any text visible in the image.
Use /status to check your setup
If something seems off, type /status to see your current language and mode at a glance.
Kanglish / Hinglish for comfort
If reading Devanagari or Kannada script is tiring, switch to Hinglish or Kanglish - you get the same language in easy-to-read English letters.
Ask for structured output
"Give me a bullet-point list", "Summarise in 3 lines", "Give me a table comparing X and Y" - the bot formats its output based on your instruction.
