sylearn/AIUsage ? reverse-engineered prompt

Build me a native macOS app that acts like one dashboard for all my AI subscriptions. I want to add multiple accounts for providers like Claude, Codex, Cursor, Gemini CLI, and OpenCode, then see quotas, costs, token usage, and account status in one place. It should have a clean menu bar view, a main dashboard with charts and progress bars, and a way to switch active accounts or proxy nodes with one click.

Also include support for a few local proxy tools so I can point Claude Code, Codex, and OpenCode at different upstream models, with a managed gateway mode that can share one account pool across apps. Please store credentials safely in Keychain, keep everything feeling native and polished, and make it easy to download and run on macOS 14 and up. If you need to look up current docs online for any of the proxy details, go ahead.
