In plain English

AI coding tools send and receive a lot of text, and Headroom, run by Garm, is a small app that sits in the menu bar, the strip of icons at the edge of the screen. It quietly trims extra filler and repeated standard text, and it shortens long documents without throwing anything away. People who pay those coding tools based on how much text they send buy Headroom because a shorter message can mean a smaller bill. The AI does most of that trimming and the billing. The team still checks quality, helps users, and handles cases where something important must not be cut.
