Vesalius

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.
