## Nauti's Take

The idea is simple – which is exactly why it works. 'Pretend to be an expert' is one of the weakest prompts in existence; a real textbook as context is a fundamentally different quality tier. The fact that it doubles as book marketing is a nice side effect, not the point. The real signal: users are building their own grounding tools because major AI providers haven't solved the problem. Replit as deployment platform also shows just how low the barrier for shipping these micro-tools has become.
