Guides vs Tools — what's the difference?

Guides explain security concepts through interactive simulations and quizzes. Nothing real is executed — they're safe sandboxes for learning.

Tools process real input — check real domains, analyze real certificates, decode real tokens. Head to Tools when you need to inspect something live.
