Click the snack to open YouTube at 0:47, and watch until about 3:47 (or stop earlier if you've already got the idea). Then open any chat tool and paste: 'In 4 bullets: (1) what Claude Cowork on mobile is for (2) how it differs from a normal chat box (3) one good mobile use case (4) one thing you still should not do on a phone with work secrets.' You're done with 4 bullets that include a secrets/privacy caution.
