Short answers about QSI, the free SI (synthetic intelligence) assistant made in India: what it costs, which languages it speaks, how live voice works and what happens to your chats.
QSI (Quantum Synthetic Intelligence) is an SI (synthetic intelligence) assistant, which means an AI assistant, made in India. It works in your web browser at quantumsi.in, on your phone or your computer. You can chat with it, talk to it with live voice, ask it about your photos and documents, and download its answers as files. See everything QSI can do.
Yes. You can use QSI free as a guest, with no account, for example 30 chat messages and 3 minutes of live voice a day. Log in free with your email for much higher limits, such as 300 chat messages and 15 minutes of live voice a day. Daily limits reset at 5:30 AM IST. A paid plan, QSI Pro, is launching soon for people who use QSI a lot.
No. You can use QSI as a guest. Logging in with your email is free and gives you higher daily limits, web search and on-screen cards in live voice, and picture making.
SI stands for synthetic intelligence. It is the name we use for QSI’s kind of AI: QSI is an SI assistant, which means an AI assistant.
No. “Quantum” is part of our name only. QSI does not run on quantum computers.
No. QSI is an AI assistant for chat, voice and documents. It is not an investment, trading or money-making service, and we will never ask you to invest money. If someone offers you returns or trading profits in QSI’s name, it is not us. Please tell us at hello@quantumsi.in.
English, all 22 scheduled Indian languages and many other languages, on every plan: Assamese, Bengali, Bodo, Dogri, Gujarati, Hindi, Kannada, Kashmiri, Konkani, Maithili, Malayalam, Manipuri, Marathi, Nepali, Odia, Punjabi, Sanskrit, Santali, Sindhi, Tamil, Telugu and Urdu. English and Hindi work best. The other Indian languages are best effort and may be less accurate.
Yes. QSI runs in the web browser on your phone or computer, so there is nothing to install. Open quantumsi.in and start typing or talking.
Alpha Core (code, debugging and system architecture), Beta Mind (research, reasoning and analysis), Gamma Link (live web search, with links to sources), Delta Shield (fact-checking, safety and error correction), Epsilon Flow (writing, polishing and pulling answers together) and Zeta Grid (task mapping and planning). Leave QSI on Auto and it picks the best agent for each message, or choose one yourself. The agents are parts of QSI, not people.
For bigger tasks, switch from Chat to Swarm. Zeta Grid splits your task into steps, the specialist agents work on them in parallel, Delta Shield can review the work, and Epsilon Flow combines it into one answer. You can watch every step live. Guests get 3 Swarm runs a day and free members 40.
Yes. For news, prices, weather and other up-to-date questions, QSI can search the web and show links to its sources. Leave search on Auto, or turn it on or off. In live voice, web search is available to logged-in members.
Yes. Add photos, take one with your camera, or attach documents such as PDFs, Word files, text and code files, and ask about them in English or an Indian language. Guests can send 5 messages with photos or files a day, and free members 40.
Yes, anyone can. Under an answer, choose Download as, then PDF, Word, PowerPoint, Excel or Print. In PowerPoint each heading becomes a slide, and in Excel each table becomes a sheet. The file is made on your device, in your browser. In live voice you can also ask QSI for a document and download it.
Logged-in members can describe a picture and QSI makes it, up to 10 pictures a day. Every picture has a small “AI-generated” label. QSI checks every request first and refuses pictures of real people, nudity, anyone who is or looks under 18, fake documents and anything else our picture rules don’t allow. Picture making can pause for everyone when QSI’s overall picture limit is reached.
Tap the voice button next to the message box and talk with QSI in real time. You can interrupt it whenever you like, and it replies in the language you speak. Guests get 3 minutes of live voice a day and free members 15 minutes a day. Logged-in members can also ask it to search the web and to show steps, lists, drafts or links as cards on screen.
Yes. During live voice, use the file button to share a PDF, Word, Excel, CSV, PowerPoint or text file, then talk about it. Your browser reads the file and sends only its text, up to 5 files in one voice session. The file itself is not uploaded.
Yes. You can listen to any answer in a natural QSI voice, or in your browser’s own voice. You can also tap the mic and speak your message instead of typing it.
Your chat history is saved only in your browser, on your own device. QSI’s server does not store your chats, and you can delete them at any time with Settings → “Clear all”. To answer you, your messages are sent to the AI services QSI uses. Our main AI service provider may keep them for up to 30 days to check for abuse and misuse; the backup service and its model hosts follow their own policies. We do not use your chats to train AI models. Section 3 of the Privacy Policy has the details.
No. QSI has no ads, no analytics and no tracking, and we don’t sell your data. The only cookie QSI sets is a login cookie, and only if you log in.
We design, build and run QSI: its six agents, Agent Swarm, its voice features and its daily limits. The answers, the voices and the reading of your photos and documents come from AI models offered by AI service providers, which we use through their developer services. Section 3 of our Privacy Policy explains what each provider receives, and you can ask us for their names at privacy@quantumsi.in.
Yes. Like any AI, QSI can be wrong, incomplete or out of date, so please check anything important yourself. For health, legal or money decisions, get advice from a qualified professional.
QSI is meant for people aged 18 or over.
