About AI Tracker
AI Tracker is a local-first Next.js application designed to monitor, analyze, and estimate costs for your AI CLI tools. By reading the local log files generated by AI assistants (like Antigravity and Claude), it provides a unified dashboard to track your usage and expenses.
The application runs entirely on your machine, parsing your `.jsonl` transcript files locally. It calculates approximate token usage and costs based on specific pricing models, supports filtering by tool and time range, and ensures your data remains completely private.
For detailed configuration instructions, advanced features, and troubleshooting, please check the official README on GitHub.
