We build one thing: a tutor that will not give the answer
tutor.ai is an independent product built around a single constraint. Everything else — the voice, the whiteboard, the uploads, the progress bars — exists to make that constraint workable rather than annoying.
This page describes who we are, how the thing is built, and what we have deliberately chosen not to do.
Who we are
Short answer: a small group building a study tool, with no partners to name and nothing to announce.
There is no company logo wall on this site and no investor list, because there is nothing to list yet. We are not going to invent a founding story or borrow a university crest to look established — if you have read this far, you have noticed that this page is unusually free of claims, and that is deliberate.
What we will tell you is what we are good and bad at. The tutor is patient, consistent and never tired, which is genuinely useful at eleven at night. It is also an AI, it can be wrong, and it is not a replacement for a teacher who knows you. We would rather you knew both halves of that before a session than after one.
How we build
Three choices that shape everything a student sees.
The reasoning is visible, not hidden
The tutor’s behaviour is a written policy: a hint ladder with five rungs that it may climb exactly one rung per turn. Because the ladder is explicit, a session can be read afterwards and the hint sequence checked against it.
We test whether it leaks answers
Every reply passes through a deterministic, rule-based check for finished solutions before it is shown. It is deliberately simple so that we can predict it and re-test it offline, rather than trusting a model to police itself.
Progress is a projection, not a score
Mastery is computed from an append-only log of what happened — attempts, hints, explanations — so we can replay the whole history and get the same numbers back. If we change the estimator, nothing is lost and nothing is silently rewritten.
How we know it works
We can describe the machinery precisely. We cannot yet tell you how much it helps, and we are not going to pretend otherwise.
The hint ladder is a rule, not a vibe
Five rungs, one per turn, never skipping to the last. That is a testable claim: replay a session and you can check whether the tutor kept to it, rather than taking our word for it.
Per-skill mastery is arithmetic you can check
A correct answer with little help moves a bar more than a correct answer after five hints, incorrect work moves it down, and the result is clamped between 0 and 1. The formula is short enough to read in one sitting.
The answer-leak check has a count
Every flagged reply is counted per session and shown to a linked parent. That gives us a number we cannot quietly drop if it goes the wrong way.
What we do not have
We have not run a study. There is no control group, no measured improvement in grades, no percentage of students who “passed their exam”, and no testimonials. If a competitor’s site offers you those numbers, ask them for the study; if ours ever does, hold us to the same standard.
Limits
What we deliberately do not do
Some of these cost us conversion. They are still the rules.
Invent social proof. There are no testimonials, no customer counts, no school or university logos and no “trusted by” claims on this site, because we do not have them.
Claim certifications we have not been audited against. We describe what we do, and we say when something is unfinished.
Publish studies we have not run. We have no outcome data yet; we describe the mechanisms instead, and you can judge them.
Store audio. Voice is transcribed once and discarded.
Give answers. If a marketing page ever promises a shortcut to the answer, it is a bug in the copy and we want to hear about it.
How these pages are built
Accessibility is a product requirement here, not a later pass — the students most likely to need a patient tutor are often the ones a fiddly interface loses.
- One h1 per page, sections in heading order, and no skipped heading levels.
- Every control has a visible label, and every interactive element is reachable by keyboard.
- Text and controls use the palette in our design system, which was chosen for contrast on the paper background.
- These marketing pages render and navigate with JavaScript switched off.
- Decorative art is hidden from assistive technology; nothing meaningful is conveyed by colour alone.
We have not commissioned an external accessibility audit, so we describe what we have done rather than claiming conformance with a standard. If something does not work for you, that is a bug worth reporting and we would rather hear it than not.
Read the safety page before you decide
It explains exactly what we store, what a parent can see, and what this tool is not.
