// features
Built for security professionals
Real Commands
Type actual nmap scans, YARA rules, and bash pipelines — not 'the quick brown fox.'
Special Characters
Master pipes, brackets, flags, and operators. The characters that actually slow you down.
19 Courses
From nmap to YARA, bash to Nix, malware analysis to incident response — real tools, real commands.
Precision Scoring
Accuracy weighted heavily — because a typo in rm -rf is not the same as misspelling 'the.'
Keystroke Audio
4 synthesized sound profiles. Mechanical clicks, soft thocks, typewriter strikes, or synth blips.
Survival Mode
Mixed prompts from all courses. Three strikes and you're out. How long can you last?
Interactive Learning
Breakdowns, quizzes, cloze exercises, and spaced repetition. Learn why commands work, not just how to type them.
Vim Mode
VimGolf-style editing challenges across every mode. Toggle in settings and every prompt becomes a vim workout.
