The gap
More than a quarter of students miss a pass in maths.
Schools are stretched and teachers more so. The help a student needs at nine on a Sunday night is not there.
Why Bluebell?
The honest version. Bluebell is an AI tutor that takes a student from GCSE to a university offer, and refuses to do the work for them. Six reasons it exists.
The shortcut
Students will use AI. That part is already settled.
The open question is whether the tool they open does the thinking for them.
The answer
Bluebell has the answer. It will not hand it over.
It asks the next question instead: a hint, a step, a smaller foothold when you are stuck. You leave with understanding, not something to copy.
The evidence
A randomised trial: more learned, in less time.
Kestin et al. (2025) ran a well-built AI tutor against an active-learning class. The tutored students also felt more motivated.
Scientific Reports →The price
From £5.99 a month.
Partner schools hand it out free with a code. A tutor is £40 an hour, and cost should be the last reason a student goes without.
See pricing →The scope
Four subjects, GCSE through to an offer.
Maths, biology, chemistry and physics, GCSE and A-level, on AQA, Edexcel and OCR. Then Oxbridge interviews and the UCAT.
The founder
I use AI every day and it has never once given me understanding. It gives me output. Students will reach for it whatever anyone says, so the one they reach for had better be the kind that makes them think.

I’m Raunaq, a PhD student in astrophysics at UCL. I went through GCSEs, A-levels and university applications, and what stayed with me is how unevenly the help is spread. Some students have tutors, revision courses and stacks of past papers. Some have none of it, and the gap that opens is not about ability.
Bluebell is not a replacement for a teacher. It is the thing the second group never had, at eleven at night, for a few pounds a month.
Next: more subjects, and a view for teachers of how a class is getting on.
