Talk to AI in Hindi and 22 Indian languages, by voice
QSI is a free Synthetic Intelligence (SI) platform, made in India for the world. Tap the voice button, speak in your language, and hear the answer in the same language. 3 minutes a day as a guest, 15 minutes a day with a free email login, and nothing to install.
How to talk to QSI (3 steps)
- Open quantumsi.in in the browser on your phone or computer. No app, no download.
- Tap the voice button next to the message box and allow the microphone when your browser asks.
- Speak in Hindi, Marathi, Tamil, English or any of the 22 scheduled Indian languages. QSI answers by voice in the language you spoke, and shows steps, lists, drafts or links as cards on the screen when that helps.
Start speaking at any time to interrupt it. It stops, listens, and continues from what you said, so you can ask for a shorter answer, a slower one, or a different question.
हिंदी में: “मेरी बैंक पासबुक खो गई है। नई पासबुक के लिए बैंक मैनेजर को एक छोटा आवेदन पत्र लिखो।”
मराठीत: “पुरणपोळी कशी करायची? पाच स्टेप्समध्ये सांग.”
தமிழில்: “3/4 + 1/8 எவ்வளவு? படிப்படியாகச் சொல்லு.”
In English: “Explain how a UPI AutoPay mandate works, in two minutes.”
What you can do by voice
Ask anything, hear the answer
Questions, explanations, letters, recipes, homework steps. QSI speaks the answer and can put the draft or the steps on screen as a card.
Search the live web
Ask it to search, and it uses the live web for today’s facts before it answers.
Talk about a file
During live voice, use the file button to share a PDF, Word, Excel, CSV, PowerPoint or text file, then ask about it. Your browser sends only the text, up to 5 files in one voice session; the file itself is not uploaded.
Speak instead of typing
Tap the mic and dictate your message. QSI turns what you say into text, in your language.
Listen to any answer
Have any written answer read aloud in a natural QSI voice, or in your browser’s own voice.
Keep the answer
Ask for notes or a summary and download them as PDF, Word, PowerPoint or Excel. How downloads work.
