Vectorscope
An AI linear-algebra tutor that explains every concept through interactive, manipulable 3D figures you can drag, rotate and project — so vectors, eigenvectors and transformations stop being symbol soup.
Undergrad and self-taught students stuck on linear algebra for ML, engineering or physics courses
- Conversational tutor that picks up from "I'm stuck on eigenvectors" and walks through it using a manipulable 3D figure rather than static diagrams
- Side-by-side "symbol ↔ geometry" toggle that lets you see the same idea as an equation and as a visual transform (stretch, rotate, project), with one-click switch
- Curated learning paths tied to real downstream needs — "linear algebra for ML," "for robotics," "for graphics" — each path is ~20 hours of guided interactive content,Progress checks that surface the exact figure you need to manipulate to prove you understand a step, not just multiple-choice recall
HN gave the original interactive linear-algebra book 154 points and 24 comments — clear proof learners want visual math — and the current LLM moment finally lets a single figure be turned into a personalized walkthrough instead of a static page everyone reads the same way.
Multiple Reddit threads, 'is linear algebra hard' SEO articles, and dedicated tutor sites (finishmymathclass, mymathexperts) confirm a real struggle-base of undergrads and self-taught learners.Why is Linear Algebra so torturously hard for me? - Reddit ↗Is Linear Algebra Hard?

The AI math-tutor market is crowded (Khanmigo, Photomath, Symbolab with 138K Play reviews, Wolfram, Mathway, Chegg) and a free Streamlit-based Linear Algebra Visualizer already exists; only the 'manipulable 3D + AI walkthrough' angle is open.11 Best AI Math Tutoring Tools 2026 (Step-by-Step Help) ↗Linear Algebra Visualizer (2026) | Interactive Streamlit-based platform ↗
Proven $7-10/mo subscription willingness (Symbolab Pro $6.99/mo, Photomath Pro $9.99/mo, tutors $25-80/hr); undercutting human tutoring is a viable wedge, but no direct evidence users would pay for a linear-algebra-only product yet.Symbolab Review 2026: Free Tier Limits, Pro Cost & Accuracy Testing ↗Photomath vs Symbolab 2026: Which Math Solver Wins? ↗
Linear algebra is foundational and growing for ML/engineering/physics; the HN interactive-figures thread itself has stayed relevant across multiple HN reposts for nearly a decade.Immersive Linear Algebra - textbook with fully interactive figures (2015) (immersivemath.com) ↗Immersive Linear Algebra - A free interactive online book ↗
Doable with Three.js/Babylon + LLM prompt layer (Streamlit-based visualizer prototype already shipped by a student), but non-trivial to author a full 3D-figure library and tie every concept to a manipulable scene.Linear Algebra Visualizer (2026) | Interactive Streamlit-based platform ↗Interactive Linear Algebra Learning Platform ↗
