Busy people carry a running list in their head: errands, meetings, small facts about people. Writing it down means picking an app, a list, a format, so most of it never gets captured. Pem removes the sorting step.

Replies only when there’s work done
An action or a date becomes task and calendar cards. A plain fact stays quiet, with a small “Saved to memory” line. A reply means Pem did something.

Pem started as a speech bubble merged with the letter P. Outline versions read as a ghost and pinched at small sizes, so I moved to one solid filled shape that holds up at 32px and as an app icon.

I let the P go. The mark is stronger without forcing it. The same bubble is the app icon, the mascot and the small mark beside every reply.

Pem isn’t decoration. It listens after a voice note, looks when you send a photo, thinks over text and pops a crown when the work is done. Four states, built in Rive.
