PrepGraph · India · United States
A tutor that has mastered the syllabus — and is studying you.
Students & parents
One tutor. Two countries. Pick yours.
PrepGraph maps every concept of your exam onto a live graph of what you actually know. Then it tutors you — one-on-one, out loud, like a person — on precisely the concepts standing between you and your goal.
The loop the tutor runs
The loop the tutor runs, in five steps: set a goal, diagnose, tutor, update the graph, aim the next session. The next section lists the same five steps.
Swipe sideways to see every step.
The system
Three instruments, one loop.
A tutor you talk to. A graph that remembers every answer. A plan aimed at your exam date. Ask out loud, mid-homework — it explains, questions back, and doesn’t move on until you can say it yourself.
- 01 Set a goal and take a baseline diagnosis.
- 02 Learn in one-on-one tutoring sessions.
- 03 Every answer updates your mastery graph.
- 04 Weak concepts surface before they cost marks.
- 05 Tomorrow’s session aims at exactly those — until exam day.
Why does the disc reach the bottom before the ring?
Mic stays open — talk back like it's a real tutor. It is.
A session, out loud: the tutor explains on a whiteboard and asks back.
Every answer moves the map of what you know.
Every Monday morning, one clean report.
PrepGraph sends parents a single weekly snapshot — practice consistency, score trends, weak topics, what to focus on next.

- Sequences & Series

Your exam

Since when
What we have done, with a date on each
What we did, and when.
- 01 We have had a voice tutor in the codebase since December 2025 and on Google Play since July 2026.
- 02 A school login has been a printed badge and a short PIN since 29 August 2026 — no email, no password to reset, no account a child has to create.
- 03 Student speech and text have gone to approved AI endpoints in Azure India and to named speech providers, and nowhere else, since 30 August 2026 — enforced by configuration.
The company

- Built to enable the whole institution. A tutor for its students, a programme for its teachers, a session for its leaders and a portal for its office — and a person on the other end of the form.
