Built on strong

foundations.

Simply designed around you

Customise every detail to fit your workflow.

Security without compromise

Meet the standards regulated industries demand.

Precision in every comparison

Catch every change, every time.

Simply designed around you

Built to work the

way you do.

Deploy your way. 

Hosted or self-hosted.


Run on Draftable's cloud for instant setup, or deploy on your own infrastructure via Docker, Kubernetes, or AWS. Same API, same accuracy. You choose where it runs.

Compare across document types.


Word, PDF, PowerPoint, Excel, RTF, and plain text. Compare a PDF against a Word document, or a PowerPoint against an earlier version. No conversions needed.

Get results in the format you need.


Embed visual comparisons with iframe, share direct URLs, export as PDFs, or get every change as structured JSON for reporting and automated workflows.

Scale without
limits.


Priced by volume of comparison, not per user. Self-hosted instances include unlimited comparisons. Share results with as many people as you need at no extra cost.
