The tutor I needed at 2am before an exam. Now it watches your whole class.
Quanta started as one student’s own revision tool for real Cambridge papers. It grew into a tutor that knows what each student is weak at, an examiner-accurate marker, and a dashboard that tells you who needs you this week.

A personal tutor
One thing to do next, decided for them
Every student gets a tutor that watches what they actually do: which skills are weak, what they haven’t touched in three weeks, an unfinished paper from yesterday, and every deadline you’ve set. It turns all of that into one recommendation, not a list. Set an assignment and it slots itself into the queue on its own — no reminder emails from you.
The gaps it finds are skill-level, not topic-level. “Trigonometry” tells a student nothing. “You lose marks converting between degrees and radians” tells them exactly what to fix.
Deciding what’s next is half the job. Here’s the other half.
One student’s plan, this morning
Finish marking Feb/March 2025, Paper 22
Started 40 minutes of this paper yesterday and didn’t mark it. Finishing beats starting something new.
Ms. Patel set Oct/Nov 2025 P41 as homework
Two days out. Starting now leaves time to fix whatever it turns up.
How it teaches
Knows when to ask, and when to just tell them
The same tutor that picked the task also teaches it. A tutor that only ever asks questions is exhausting when a student is genuinely lost. One that only ever explains teaches nothing. This one reads the moment and switches: a nudge when a nudge will do, a straight explanation when the student is stuck cold.
It’s tuned to the subject it’s marking, not a generic chatbot bolted on. Every conversation is saved against the question it came from, and every message is rate-limited so it can’t become a crutch.
Same question, two students
Real past papers
Answer the actual paper, right here
54 real Cambridge papers so far, across A Level Pure Mathematics 1 and IGCSE Extended Mathematics, with new ones added every month. Students work the paper the way it’s actually sat, type the final answer, then mark themselves against the official scheme, criterion by criterion.
No separate mark scheme PDF. No spreadsheet of results to chase down. Set it as an assignment and the score is in your dashboard the moment they submit.
June 2024, Paper 12 · Question 7
Find the coordinates of the stationary point on the curve.
Marked against the official Cambridge scheme — 4/4
For teachers
Zoom in as far as you need to
Start with the whole class. Drop into one student. Read exactly what they told the tutor when they got stuck.
1. Class heatmap
Every skill, every student, one grid. Red cells are where the whole class needs reteaching before the mock.
2. Per-student trend
Click into anyone and see their own mastery and trend line, not the class average standing in for them.
3. Tutor transcripts
Read the actual conversation. When a student says “I don’t get it,” you can see exactly where it stopped making sense.
Why this exists
Built while sitting the same exams it teaches
Quanta didn’t start as a company idea. It started because one student, working through Cambridge past papers alone at night, wanted something that could tell him what was actually wrong with an answer, not just that it was wrong. He built it for himself first, mapped the papers by hand, and only later realised a whole class could use the same map. That’s still how every paper gets added today — checked by hand, question by question, against the real mark scheme.
Running a pilot
One class, no setup
Payment and department-wide licensing can wait until you’ve seen it work on one class.
Students join with a code
No IT ticket. Students sign up with an email address and join your class the same afternoon.
Set your first assignment
Pick a past paper, set a due date. The tutor takes it from there.
Watch the map fill in
Within a fortnight you have a real per-skill picture of the class, and something to show for your next department review.
Trust & data
For the questions a safeguarding lead actually asks
Most Quanta students are 14–18. Here’s what we tell every parent and every DPO who asks.
You control the data
Where Quanta runs through your school, you're the data controller and we process on your instructions. A data processing agreement is available on request.
Two-click deletion, a real retention date
Students can delete their account and full record instantly; backups clear within 30 days. Inactive accounts are deleted after 24 months, with a warning first.
An AI tutor with a leash
Maths-only, rate-limited per student per day, switched off entirely in mock mode. Every conversation is visible to the class teacher.
No ads, no trackers
An account is a name and an email. No advertising, no third-party analytics, no selling data. Four named subprocessors run the app, listed in the privacy notice.
The full privacy notice is written to be read by a 15-year-old, not just a lawyer.
We need your help
Less marking for you. A sharper map for them.
A pilot means papers that mark themselves against the official scheme instead of landing on your desk, and a dashboard that flags who needs you before the mock does. Your evenings get shorter and their results get better.
It also means Quanta gets built by people who actually run a classroom. Tell us what’s broken, what’s missing, and what you wish it did. Mathematics is live today; Economics, Physics, and English are already on the list — tell us which one your department needs first.
