Document tools that never see your files
OCR, signatures, certificates, diagrams, email helpers, Markdown, and spreadsheets — one host. Invoice Studio and Rezimo stay on their own hosts because you draft those documents, not run a one-shot job.

How these tools are written
Simon Wong ships the apps in the same web-tools-hub repository as Tool Hub. This host exists so docs work is grouped the way file work is grouped — not so every leftover product gets its own subdomain. Guides on sw-commercial.com stay unpublished until a path here returns HTTP 200.
