About SERP

SERP builds everyday software: Keybumps for Mac, Zenbu Japanese for iPhone, and free tools, games, and checklists for everyone.

Our mission

Make the internet more useful, one tool at a time.

SERP is an independent software company. We build and run our own products: Keybumps, a set of Mac utilities in one app; Zenbu Japanese, an offline-first Japanese dictionary for iPhone; SERP Tools, free online file converters; SERP Games, free games you can play in your browser; and SERP Lists, for turning processes into checklists you can run. We share what we learn in videos and posts.
