Steve Ruiz, founder and CEO of tldraw, demonstrates the company's AI experiments on their infinite canvas, including Make Real—which turns hand-drawn wireframes into working web apps using vision models—and tldraw computer, a visual programming environment where arrows and LLMs power a graph of connected nodes that can execute multi-step prompts, generate images and speech, and even run loops indefinitely. He also shows Draw Fast for real-time image generation and Teach, where Claude can draw and edit shapes on the canvas. The episode explains how tldraw's SDK (tldraw.dev) enables others to build custom canvas applications, and highlights the company's philosophy of 'shitty but amazing' rapid prototyping.

Excalidraw: AI and Human Whiteboarding Partnership - Christopher Chedeau

Jul 21, 2025 · 16:59

Christopher Chedeau, creator of Excalidraw, explains how to integrate AI into whiteboarding by focusing on turning prompts into editable diagrams rather than static images. He argues that just adding any AI model harms the product, citing a failed attempt to generate realistic images because users don't draw realistically. The successful integration uses Mermaid.js to output Excalidraw files, letting humans modify the AI-generated diagram. He envisions a future of iterative human-AI collaboration, and demonstrates other practical features like auto-naming files, generating illustrations (coming soon), and challenges AI engineers to build a browser-based logo background remover. He concludes that the industry is in a physical-to-virtual transition for AI, and that LLMs work best when targeting a structured domain-specific language.
