Core text transformations and generators run in the browser so pasted content does not need to leave your device.
Practical guides
The strongest tools now have original supporting guides that explain when to use them and what mistakes to avoid.
Visible support path
The site now has a dedicated contact page and support portal instead of burying help behind placeholder text.
