Score: 5.0/10 (Innovation: 5, Technical: 4, Documentation: 4, Utility: 6)

AI Meter is a local macOS tool that aggregates token usage from AI coding assistants like Codex, Claude Code, Cursor, OpenCode, and Gemini CLI, then estimates the associated energy and water consumption. It addresses growing interest in the environmental footprint of AI-assisted development, though the project is early-stage with sparse public documentation.

Target audience: developers concerned with AI environmental impact, sustainability-conscious engineering teams
