51% fewer tokens for Claude Code
Vesalius reads your repository once, right on your Mac, and remembers how everything connects: which file uses which, who calls what, where a feature actually lives. Claude Code can then ask it directly and get answers with exact file and line references, usually in one call instead of a chain of searches. In our benchmark that cut token use roughly in half with no measurable change in answer quality. Vesalius itself never uploads your code.
Vesalius is a developer tool for Mac that maps codebase connections within a GitHub repository, allowing Claude Code to retrieve precise file and line references efficiently. It operates locally without uploading code, reducing token usage by approximately 50% while maintaining answer quality.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
