✦ built for the age of AI

AI can write the code.
Can you tell when it's wrong?

When machines write the code, the edge belongs to the people who actually understand it β€” who can read it, run it, break it, and fix it. TermCraft trains exactly that: real bash, python, security and red-team work, executed for real and graded on the spot. Stop shipping what you can't verify. Master the machine the AI runs on.

Review the AI, don't obey it
A whole track on reading AI-written code: spot the injection, the off-by-one, the leaked secret, the hallucinated API β€” and fix it. The skill that matters when the AI writes the first draft.
