- Answers cite your notes, and say when they do not cover it
- It never writes an essay, a report, or a CAT answer
- Students join with a room code; no accounts needed

Talk to usUstadi means mastery.
A teaching assistant for lecturers who teach large classes, set CATs and main exams, and supervise research students. It works from your course, not from the internet's idea of it.
Your material comes first
Every tool drafts from the documents you upload and names the material it used. Where your notes are silent, it says so.
Students do their own learning
The room tutor explains and asks questions. It will not write an essay, a lab report, or an answer to an assessed question.
You stay the author
Everything is a draft you can edit, save, and export. Nothing reaches students until you share it.
Questions lecturers ask
Something else? support@ustadi-ai.com
What can I upload?
PDF, Word, PowerPoint, Excel, CSV, and plain text: lecture notes, slides, past papers, course outlines, practical guides. Long documents are fine; a 450-page textbook works. Scanned PDFs and phone photos of pages work too: Scan to Text reads them and flags any page that was hard to read. Ustadi drafts from them and names the material it used.
Do my students need an account?
No. In a room they enter the code, their name, and registration number. They never see your files; the tutor answers from the documents you attached to that room.
Won't students use it to do their assignments?
The room tutor is built not to. It explains, asks questions, and coaches students through problems, but it will not write an essay, a lab report, or an answer to an assessed question. You also see what the class is asking.
Is it only for science courses?
No. Any course with materials works: nursing, law, business, education, engineering, the humanities. The examples on this page happen to come from a database systems course.
Do live classes work on laptops, phones, and mobile data?
Yes. Students join from the browser on a laptop or smartphone with the room code; there is no app. Their microphone and camera start off, and Audio only stops downloading video, so a class uses far less data. Attendance is taken as they join.
Can I edit what it writes?
Yes. Everything is a draft you can edit in the browser, save to your history, and export to Word (on Plus and Pro) or Markdown.
How do I pay?
By M-Pesa or card, in shillings. You pay for a month, a semester, or a year at a time, and nothing renews automatically; Ustadi shows a reminder in your sidebar in the last week. Every new account starts with 14 days of Plus, no card needed; live classes are not part of the trial. The trial runs once and does not renew. Extra live-class hours are $5 an hour (KES 650).
