AgentNotch is a sleek macOS application designed for developers who use AI coding assistants. It lives in your Mac's notch (or menu bar on non-notch models) and provides real-time visibility into AI assistant activities. The app tracks tool calls, token usage, and estimated costs while distinguishing between different AI sources with color-coded indicators (orange for Claude Code, blue for Codex). It operates entirely locally, ensuring privacy by not sending any data externally.
Key Features:
- Real-time tool tracking for file reads, code edits, and shell commands
- Token and cost monitoring with input/output breakdowns
- Source-aware design with color-coded indicators
- Completion detection notifications
- Lightweight native macOS implementation
- Configurable display options (show/hide tokens, costs, filters)
Use Cases:
- Developers using Claude Code or OpenAI Codex who want visibility into AI assistant activities
- Teams monitoring AI tool usage and costs
- Individuals concerned about privacy who prefer local-only telemetry
- Users with notch-equipped MacBooks (2021+ models) who want to utilize the notch space productively
