The 25-Minute Build
One prompt, one timer, one shippable thing. Go.
makes 'AI makes you 10x faster' falsifiable in public, in 25 minutes, on camera — the clock either proves the productivity claim or doesn't, live, with a visible artifact at the end, instead of an assertion
What goes in, what comes out
A visible 25-minute countdown pairs the learner with a real, ephemeral sandboxed environment and one of a rotating set of small, genuinely completable build briefs. The timer is the whole game — no partial credit for elegance, only for a working, tested artifact inside the window, graded the instant time expires.
start the timer, work inside the sandboxed environment with an AI coding agent, submit before time expires
pass/fail on the graded artifact, time-remaining-at-submit stat, a replay of the build steps, comparison to the community's median completion time
brief-difficulty picker (5 rotating briefs per week), optional 'no AI assist' control-group mode for comparison, pause disabled by design
FREE, top-of-funnel — /playgrounds gallery, live booth demo at meetups/events; the same sandbox and grading powers the paid AI Coding Dojo labs
