Tools that explain their limits
Every workspace is built around a clear input, visible processing state, useful result and recoverable error path. When a task can run safely in the browser, it stays on your device.
Are files uploaded?
Tools marked Local, Local with limits or Local + downloaded code do not upload tool content. Ordinary page requests may still appear in access logs.
Why do some tools load extra code?
PDF, image, schema and archive workflows load specialized modules only when their workspace opens, keeping category pages fast.
