Private Tools Hub

Tools that respect the task

Private Tools Hub is built around a simple idea: utility software should be fast, understandable and honest about where your data goes.

Product

Our product standard

Static pages arrive first, interactive code loads only where needed, and local browser processing is preferred whenever it is practical and safe.

What we optimize for

  • Fast answers with minimal interface friction.
  • Local-first processing for text, files and calculations.
  • Clear labels when an external service is required.
  • Accessible controls that work across keyboard, touch and different screen sizes.
