Useful browser results, with the browser limits explained.
BeanNest keeps the main task compact and puts deeper guidance below the work surface. A tool reports what it can actually observe or produce in your browser; it does not claim to certify hardware, formats, or system behavior that the web platform cannot verify.
Private by design
The tools in this category are designed to keep working input in the browser. Each tool page states its exact privacy behavior and any browser or device limitations that matter for the result.
