Sparx is a UK-school-licensed maths homework platform; aitutors.me is a parent-bought Socratic AI tutor. They look similar from outside but solve different jobs. Comparison below, plus how many UK families use both.

What Sparx does well
Homework infrastructure. Sparx Maths is the UK's most widely-deployed school homework platform for secondary maths. Schools set Sparx homework weekly; students complete it online; the system marks instantly and adapts difficulty.
Curriculum alignment. Mapped tightly to UK KS3 and KS4 specifications. Teachers trust it.
Spaced practice. Sparx interleaves topics so students revisit earlier material — good for long-term retention.
Free to families. If your school has Sparx, your child gets it at no cost to you.
What aitutors.me does differently
Socratic conversation. Pi at aitutors.me is a dialogue tutor — your child can ask "I don't get question 4", and Pi will walk them through it via a 4-level hint ladder. Sparx, by design, doesn't have this. When a Sparx student is genuinely stuck on a question, the platform offers a video clip or worked example, but no conversation.
Energy-aware sessions. When your child has had a hard week, aitutors.me's Mentor agent says "let's do a short session" or "skip tonight". Sparx will assign the same homework regardless.
Personality-adaptive. Pi reads your child's interests and uses them in analogies (chess, football, music). Sparx is uniform across users.
Refuses to give the answer. Sparx will eventually let you see a worked solution. Pi will not — by design.
The reality: they complement
Most UK families using both report a sensible split:
- Sparx = the practice and homework engine (set by the school, tracked by teachers)
- aitutors.me = the "I'm stuck and need to actually understand this" companion
In numbers:
- Sparx: ~3 × 20-minute homework sessions / week
- aitutors.me: ~3 × 20-minute "talking to Pi" sessions / week
The two together cover practice + understanding. Neither covers both alone.
When you'd pick one over the other
Stick with Sparx only (no aitutors.me) when:
- Your child can do Sparx homework with minimal stuck moments
- Sparx hint structure is enough for the rare confused question
- You'd rather have a human tutor for the deeper work
- Budget is zero
Add aitutors.me on top when:
- Your child consistently gets stuck on Sparx homework and you can't explain it
- You want them to learn the method, not just complete the homework
- You'd like daily Socratic practice in addition to weekly Sparx
- You're paying for a human tutor anyway and want to cut to monthly
Replace Sparx with aitutors.me when:
- (You can't — Sparx is school-set)
- But: if your school doesn't use Sparx, aitutors.me can stand alone
What Sparx doesn't try to be
Sparx is good at what it does. It is not a tutor — and doesn't claim to be. The frustration some parents have ("why won't Sparx explain?") is asking the wrong question of the wrong tool.
aitutors.me is the explanation layer.
Pricing comparison (per family)
| Sparx only | aitutors.me only | Both | |
|---|---|---|---|
| Cost/month | £0 (school-funded) | £14 (Founding) | £14 (Founding) |
| Sessions/week | 3 × 20 min homework | 3 × 20 min dialogue | 3 + 3 = ~2hr/wk |
| What you get | Practice + tracking | Tutoring + adaptation | Both |
