What QSI can do
QSI is a free SI (synthetic intelligence) assistant, which means an AI assistant, made in India. Chat with it, talk to it, or ask it about your photos and documents, in English or any of the 22 scheduled Indian languages.
Six specialist agents
QSI has six agents, each set up for one kind of task. Leave it on Auto and QSI picks the best agent for each message, or choose one yourself.
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.
Zeta Grid
Task mapping and planning.
The agents are parts of QSI, not people. Like the rest of QSI, they are AI and can make mistakes.
Agent Swarm: agents working together
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.
Swarm suits work with several parts, for example a comparison, a study guide, a plan, or a piece of code with an explanation. Guests get 3 Swarm runs a day and free members 40.
Chat, web search, photos and documents
Chat
Ask questions, write and rewrite, study, plan your day or think a problem through. QSI keeps track of the recent conversation, so you can ask follow-up questions.
Web search with sources
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.
Photos and documents
Add photos, take one with your camera, or attach documents such as PDFs, Word files, text and code files. Ask about them in English or an Indian language, and QSI answers from what they contain.
Guests can send 5 messages with photos or files a day, and free members 40.
Talk with QSI
Live voice
Tap the voice button and talk with QSI in real time. Interrupt it whenever you like. It replies in the language you speak.
Guests get 3 minutes 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.
Share a file while you talk
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.
Voice input
Tap the mic and speak instead of typing. QSI turns what you say into text for your message.
Read aloud
Listen to any answer in a natural QSI voice, or in your browser’s own voice.
Download answers as PDF, Word, PowerPoint or Excel
Under any answer, choose Download as and pick a format. Anyone can use it, with or without an account. The file is made on your device, in your browser.
- PDFFor reading, printing and sharing
- Word (.docx)To edit the answer in a word processor
- PowerPoint (.pptx)A slide for each heading
- Excel (.xlsx)Each table becomes a sheet
- PrintPrint, or save as a PDF with selectable text
In live voice you can also ask QSI for a document, such as notes or a summary, and download it in the same formats.
Pictures for members
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 in one corner.
QSI checks every request first. It refuses pictures of real people, nudity, anyone who is or looks under 18, fake documents and anything else that our picture rules don’t allow. Picture making can pause for everyone when QSI’s overall daily or monthly picture limit is reached.
English and 22 Indian languages
Chat and talk in English, all 22 scheduled Indian languages and many other languages, on every plan, including the free ones.

Private by design
- 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.
- 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 (Privacy Policy, section 3). We do not use your chats to train AI models.
- No ads, no analytics and no tracking. We don’t sell your data. The only cookie QSI sets is a login cookie, and only if you log in.
- Accounts are optional. Use QSI as a guest, or log in free with your email for higher daily limits.
The Privacy Policy explains exactly what is sent where and what is kept.
Honest about AI. QSI is an AI and can make mistakes. Answers 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.
