// your brain is a muscle
Use it or lose it
the symptoms
−You autocomplete a function you couldn't write by hand.
−You ship code you can't explain in review.
−Tab → tab → tab - when did you last actually read code?
That's not productivity. That's atrophy.
the fix
One real snippet. Every new tab.
30 Seconds of Knowledge is a browser extension that replaces your blank new tab with one real code snippet to read - a language feature, a framework pattern, an interview answer.
No course to finish, no streak to babysit. Just one small rep, every tab - the fundamentals stay in your head, not just in the autocomplete.

1500+reps
One snippet per new tab. One rep for your brain. Pulled from 14 libraries of languages, frameworks, and interview questions - with more to come.
