For you and for your learners. Try the example lessons.
Figures. A chart with a slider for each input. This one fits a curve through two years of real data. Change any of the three inputs and the curve and both errors update as you drag.
Cases. A real situation, told in steps. At each step the learner picks what to do next from three options. The lesson then shows what happens, and why the other two options were weaker.
Quick checks. One question, three answers, a reason under each. A wrong answer explains the mistake, not just the right answer.
"I'm lost here." One button on every section. Press it and the section is explained again, a different way. Every press is counted on your dashboard.
Knows where they are. The learner adds a question on a specific piece of text or a chart that they don't understand.
Your pages only. Every answer names the lesson and figure it came from. If your pages don't cover it, it's built to say so.
Your tone, your dashboard. You set the tutor's tone of voice. You see every exchange, and learners can flag any answer.
You, in the same thread. If you want to jump in, you can reply to the learner directly in their comment thread.
Yours to switch off. A course works without the tutor. Disable it if you don't want to use it.
Bundled, and improving. 3% of each sale pays for a learner's questions: about 240 on an £80 course. It runs on Anthropic's Claude models. Questions do not train them.
Why does the duration line sit below the price curve on both sides?
Because the curve bends upward. A straight tangent cannot follow a bend, so it undershoots whether yields rise or fall. Try maturity 30 years and the gap grows.
From lesson 4, figure 1 · flag this answerFrom your material. Slides, notes, worked examples, a dataset, a notebook. We turn them into lessons, figure by figure.
Reviewed like a document. Comment, change, approve. Nothing is published until you have.
Edits reach everyone. Change a number or a figure and every learner sees it, with a note.
By lesson. Completion, quick-check scores, and where "I'm lost here" was pressed.
Blind spots. AI tutor questions grouped into themes, each with a suggested edit.
Approve once. The edit goes to every learner, with a change note.
No website? We give you an address. Own a domain? Use it. Either way, the course displays your logo and colours, not ours.
Learners pay us and we pay you. We handle all of the admin around payments, receipts, VAT, and refunds.
Sign-up, sign-in and lost passwords - we handle the admin. Your learner list, names and emails are yours to export when you need to.
Permanent access, a monthly subscription, or timed to an exam date. You choose how your audience accesses each course.
The "where is my receipt" and "I can't sign in" emails come to us, not you. Refund requests come to us too.
When the syllabus changes, we work with you to re-draft the lessons that changed. For as long as the course sells.
