Field notes
The page lays out an analyzer, differ, and ranking stage, with examples of route, authentication, database, external-call, and personal-data signals. Its sample review includes file-and-line pointers and separates behavior changes from a refactor whose semantics are described as unchanged. CLI, GitHub Action, PR comment, Web UI, and SARIF are named as delivery options; the homepage labels the product free in beta.
