Show HN: AI-credit – measure AI contribution to a codebase (ai-credits.vercel.app)

A new tool, AI-credit, has been announced to measure the contributions of AI assistants like Claude, Gemini, Codex, and Opencode to codebases. This tool allows developers to track, analyze, and report on the actual code written by these AI tools, providing a clear picture of their impact on software development. Its significance lies in its capability to ensure security and privacy by keeping all operations local, thereby averting the risks associated with cloud processing and telemetry. AI-credit utilizes a multi-adapter parsing engine to read local AI session logs, extract file operations, and verify these against the current codebase. Unlike other tools that merely count interactions, AI-credit focuses on contributions that have been implemented in production, excluding rewritten or deleted code for precise metrics. It generates visual reports in formats such as console charts, JSON, and Markdown, and supports various programming languages. This initiative is expected to provide developers with actionable insights into the effectiveness of AI tools, enhancing collaboration between human coders and AI systems.
