Show HN: ClaudeBar – live Claude usage in your macOS menu bar

- **ClaudeBar** is a free, open-source macOS app that shows your real-time Claude AI usage in the menu bar (top of screen), so you don't have to check the Anthropic website manually. - **Claude** is Anthropic's family of large language models (e.g., Claude 3.5 Sonnet, Claude Opus), competing with OpenAI's ChatGPT and Google's Gemini. - **Anthropic** is an AI safety company founded by ex-OpenAI employees, known for a focus on "constitutional" training to make models more helpful and less harmful. - Usage limits for Claude are often rate-limited by tokens (the units of text the model processes). Heavy users — developers, researchers, power users — can hit these caps mid-work, which is frustrating. ClaudeBar displays remaining tokens and reset timers at a glance. - The project is on GitHub ("Show HN" means it's being shared on Hacker News for discussion and feedback).
