Tone changer: everywhere you write on Mac and Windows
PromptDC for Desktop changes the tone of selected text in any macOS or Windows app, browser, IDE or terminal while preserving its meaning. Use the global shortcut, review the editable rewrite, then Replace or Copy.
Unfortunately, that timeline is tighter than we can deliver against responsibly. Could we extend the schedule by two weeks? That would give the team enough time to complete the work without compromising quality.
Why the rewrite is better: It removes slang and blame, states the constraint clearly, and turns the complaint into a specific, constructive request.
