Diff as a Service (DaaS)Use our REST API to compare documents


In comparison to standard diff algorithms, our HD-Diff algorithm compares on a per-character basis instead of a per-line basis. This allows for a much more fine-grained recognition of changes and better reconstruction of what exactly has been altered and in what fashion.

Conventional Diff

Comparison and visualisation available in conventional business software (e.g. Office 365, Google Docs).
