Speed up copywriting changes

Tell your team which words you've changed to make it easier to review copywriting changes.

Allow your team to quickly glance at what's changed instead of re-reading everything.

Compare versions of legal documents

Make sure you know exactly what's changed when going back and forth on legal documents.

Share your changes

Share your code change diffs in a variety of formats. Line and JSON diffs are shared as diff patches, similar to how Git displays diffs.

Word and character diffs can be shared as both rich text and Markdown (where supported).
