Chat and talk with QSI in English and 22 Indian languages
QSI is a free Synthetic Intelligence (SI) platform, made in India for the world. Type or speak in your language and QSI answers in the same language, with nothing to set up and nothing to install.
How it works
Open quantumsi.in in the browser on your phone or computer. Type your question in your language, or tap the voice button and speak. QSI replies in the language you use and keeps track of the recent conversation, so you can ask follow-up questions. It works for guests (30 chat messages a day, no account) and for free members (300 a day when you log in free with your email). Daily limits reset at 5:30 AM IST.
Live voice in your language
Talk with QSI in real time and interrupt it whenever you like; it replies in the language you speak. Guests get 3 minutes of live voice a day and free members 15 minutes, with each call lasting up to 15 minutes. While you talk, you can share a PDF, Word, Excel, CSV, PowerPoint or text file and ask about it (up to 5 files in one session; only the text is sent, the file itself is not uploaded).

Which languages work best
English and Hindi work best. The other Indian languages are best effort and may be less accurate, so check anything important. For Bodo, Dogri, Kashmiri, Konkani, Maithili, Manipuri, Sanskrit, Santali and Sindhi, answers can be noticeably weaker: QSI will try, so keep questions short and simple. Like any AI, QSI can make mistakes in every language.
All 22 scheduled languages
Every language below is available on every plan, including free. Each block shows the language in its own script, one sample question you can paste or say, and what it means in English.
