Document review & annotation
Surface
A local-first workspace for document reading, annotation, and contextual AI assistance.
Surface is a local-first workspace designed to bring document reading, precise annotation, and contextual AI assistance together. The goal is a calm place to understand source material, ask focused questions, and turn observations into useful feedback while keeping control of the original files.
Annotations stay anchored to the words and page geometry that prompted them, so comments remain useful as the view changes. When review is complete, Surface keeps the original document intact and exports annotations and readable feedback beside it, giving writers and collaborators a clear handoff they can inspect, share, and keep.
