Mac app "Braincell" adds animated companions for Claude Code users

A developer has created "Braincell," a small, free application for Mac users that displays two animated creatures in the menu bar. These creatures interact when two friends are simultaneously using Claude Code, appearing to share or contend for a "braincell." The application is lightweight, uses minimal system resources, and prioritizes user privacy with encrypted messages and no data retention. It was developed using Fable 5.2, which assisted in writing the app's code, installer, and encryption features. AI

IMPACT Provides a novel, privacy-focused social interaction layer for collaborative coding with AI.
