WordCanvas3D - See how AI reads text: tokens, embeddings and vector math

WordCanvas3D is a free, open-source playground for how AI understands text. Split any sentence into tokens and compare how GPT and LLaMA tokenizers see it. Fly through thousands of words in 3D and watch similar meanings cluster together. Do math with meaning, like king − man + woman ≈ queen. New in v2: a Learn section with beginner-friendly articles and interactive figures, a full redesign, phone support, and English, Chinese, Japanese and Spanish.

Hey Product Hunt 👋 I launched WordCanvas3D here about a year ago. It was a rough first version and, honestly, it didn't land. So I rebuilt it. The idea is simple: make the way AI reads text visible. Language models don't see words, they see tokens and long lists of numbers. WordCanvas3D lets you see that for yourself: 🔤 Tokenizer: paste any text and see exactly how GPT and LLaMA split it (and why emoji and other languages cost more) 🌌 Embeddings in 3D: fly through thousands of words and watch related meanings cluster together ➕ Vector Playground: king − man + woman ≈ queen, drawn as arrows 📚 Learn (new): beginner-friendly articles with interactive figures, from "what is a token?" to how a transformer picks the next word Also new in v2: a full redesign, proper phone support and four languages (English, 中文, 日本語, Español). It's free, has no ads or sign-up, runs in your browser, and is open source. I'd love to know what confused you, what you'd like to see explained next, and which word you searched first 🙂
