WhatA hands-on interactive tool that lets users trace a single prompt through every layer of a transformer — tokenizer to sampling — with live visualizations of the actual math at each step.
SignalMultiple commenters express frustration that existing LLM explainers are either too high-level (AI-generated slop) or too scattered, while those who built their own mental models (whiteboard block diagrams, watching slow token generation) found that the architecture is surprisingly simple once you walk through it step by step — there is a gap between chatbot-generated explainers and the deeply satisfying hands-on understanding people crave.
Why NowLLMs are now mainstream but understanding them is gatekept by either academic papers or low-quality AI-generated content, creating massive demand for genuinely good interactive education tools as millions of developers and product people need to build on top of these systems.
MarketDeveloper education and upskilling market; tens of millions of software engineers and technical PMs need LLM literacy; competes with Karpathy's free content and 3Blue1Brown but no one owns the interactive, step-through-the-math product; enterprises would pay for team training licenses.
MoatHigh-quality interactive visualizations are extremely hard to build and maintain as architectures evolve; first mover with a genuinely great product builds brand and word-of-mouth distribution in a space where quality is rare.
