Local and read-only

AgentLens reads the files the clients leave on your machine and never writes to them. Nothing leaves the machine unless you ask for exact token counts.

Measured or estimated, always marked

Every number says whether the client measured it or AgentLens estimated it (a tilde). Missing data is n/a, never a guess.

CLI, application and export

The same analyses in a command line, a desktop application and as JSON, CSV or a self-contained HTML report.
