What is an agent harness?
Everyone argues about which model is best. Almost every agent that fails in production fails in the scaffolding around it. The six parts of that scaffolding, one at a time, with animation.

Short visual explainers on the ideas behind the tools — no maths, and every animation can be replayed.

Read the explainer →Every chatbot sits on a model that remembers nothing. Six short animations show how Claude, Claude Code and ChatGPT fake remembering — and what that means for cost and accuracy.

Interactive tools you can play with — change any input and see the result instantly. Nothing to install, nothing to sign up for.
What does an AI support conversation actually cost? Compare models side by side, and see why long chats get expensive when every reply resends the whole history.
Open the calculator →AI doesn't read words — it reads tokens. Type any sentence and watch it get split into tokens step by step, the same way most AI models learn their vocabulary.
Open the visualizer →AI stores meaning as position. Every word becomes a point in space, and words with similar meanings land close together. Search for “doctor” and see which words sit nearest to it.
