What’s new

A running log of what we’ve shipped. Newest first.

Visual Calculus & a galaxy knowledge graph

Jun 23, 2026
  • New Visual Calculus lab — the calculus that powers AI/ML, taught through its ML role: derivatives as loss gradients, partials and the Jacobian, the Hessian and curvature, and backpropagation as the chain rule through a network. Each concept pairs an interactive graph with ML-framed practice.
  • The knowledge graph has a new look

Interactive visualizations

Jun 6, 2026
  • Coding problems can now draw a live graph from your solution — slide a parameter and watch the curve, decision boundary, or loss change.
  • Topic pages show intuition graphs next to the research papers (starting with the bias–variance tradeoff).
  • Every graph supports a short “what to notice” caption.

Tensor Code & focus timer

Jun 6, 2026
  • The landing page now features Tensor Code — 90+ from-scratch problems across guided tracks, run in an isolated sandbox.
  • The topic-page focus timer is now a calm Pomodoro with an optional, dismissible break nudge.
