I studied computer science and math. The ideas come from somewhere else.

→ Letterbddy turns thousands of logged films into a map of your taste: clusters you can navigate, not a list.

→ Gesso is a daily game where reasoning about period and brushwork can get you close even if you’ve never seen the painting. Every piece comes from an open museum collection.

→ Subplot takes your whole watchlist and finds the cheapest set of services that covers it. Underneath, it’s a set-cover solver over live catalog data, minimizing spend rather than the number of subscriptions.

→ Pokerface lets you play through a hold’em hand one street at a time, with the relevant pot odds and outs explained as you go.

→ Tali lets you log an activity by texting its name, then ask things like “how long since yoga?” The local-first iPhone app keeps the timestamp, notes, history, and activity chart. Messages, SMS, Siri, and Shortcuts are all ways in.
