Lensa ML
Interactive visual guides · free for everyone

Machine learning you can see and touch

Lensa ML teaches machine learning, deep learning, and the math underneath through step-by-step visual explainers — every concept is something you can drag, tune, and watch respond in real time. No math prerequisites. Free for everyone, no account needed.

The idea

If you can see it, you can understand it.

Interactive, not static

Drag a slider and the math redraws. Every explainer is a model you run, not a diagram you read.

Built on intuition

No walls of equations. Each idea is broken into small visual steps that build the picture for you.

Connected concepts

Topics link to the ideas they build on, so you can trace a path from a single neuron to modern AI.

Built to be touched

Every idea is a model you can run

Drag a slider and a loss surface re-draws. Nudge a weight and the decision boundary bends. These aren't diagrams of ML — they're the math itself, responding in real time.
