Show HN: Tokenome – code provenance for AI-assisted work, on your machine

Tokenome is a local-first tool that links each line of code to the AI chat conversation that produced it, capturing transcripts from Claude Code, Claude Desktop, ChatGPT and Gemini and indexing them on your own machine via a CLI, web UI and MCP server. It reports a measured 38% reduction in context tokens with no measurable change in answer quality, and offers an optional self-hosted Team server (in free beta, $24 per seat per month afterward) that mirrors redacted project segments for team-wide search with attribution. Individual use on one machine is free, with no account, cloud embeddings or data leaving the device.
