I built an AI Paper Explorer using Pretext — the library that measures text 500x faster than the DOM. 6 paper cards with real research data, all heights calculated by pure arithmetic. Zero DOM reads. 2.5ms for the entire layout. Try dragging the cards and resizing your browser — the reflow is instant because there's no browser layout engine involved. Built by Cheng Lou, creator of React and ReasonML. 15.2K GitHub stars in days. This is how AI interfaces should render text. What paper breakdown tool would you build with instant text layout? Save this.
