What this AI spend tracker actually watches
Most AI cost problems do not come from one obvious invoice. They come from the combined stack: Claude Code sessions, OpenAI API calls, Cursor usage, Copilot seats, Gemini experiments, and recurring subscriptions that live in different dashboards. Tokens 4 Breakfast gives those numbers one local operating view on macOS. The goal is not accounting after the fact. The goal is to keep spend visible while you are deciding whether to continue a long build, switch models, tighten context, or pause a runaway agent.
