In development · Coming 2026
Learn by building intuition, not memorizing steps.
Tinker is a new kind of learning app for math, physics, and computer science — interactive the whole way down, with spaced-repetition that actually tracks your understanding, and visualizations you can drag. For adults who want rigor and intuition in the same product.
No spam. One email when there's something real to show.
What we're building
-
Rigor and intuition
Brilliant builds intuition and stops short. Math Academy builds procedural fluency and feels dry. Tinker pairs draggable, 3Blue1Brown-style visualizations with spaced-repetition on a hand-built knowledge graph — both in one product.
-
Knowledge graph you can trust
Every concept is a node with explicit prerequisites. Mastering an advanced topic trickles credit down the graph, so you never re-review what you've already proven you know.
-
Adult learners, not kids
No streaks guilt-tripping you. No cartoon characters. No walled garden. Built for self-directed learners — whether you're a dev brushing up linear algebra for ML or an engineer revisiting multivariable calc.

Works offline
Download a course, fly to Calgary, keep learning. Your progress syncs when you're back online. No subscription trap — pay once, learn forever is on the table.
Where this stands
Actively being built in the open. Source: github.com/SkipSupreme/svelte-mafs . Follow along on the waitlist and I'll ping you when the first wedge (Math for ML) is ready to dogfood.
