Common Scenarios & Troubleshooting
This tool is built for the moment you need a quick, accurate answer without opening a spreadsheet.
Note on errors: the most common slip-up here is a sentence that reads fine in your head but runs long once it's actually counted. If that happens, double-check your input rather than the tool — the calculation itself runs the same way every time.
Your data stays private. Everything you type runs locally in your own browser tab. Nothing is uploaded, logged, or stored on a server — close the tab and it's gone.
Behind the Scenes: The Processing Logic
This tool processes everything client-side, inside your browser window, using a simple running array held in memory for the length of your session. Pre-set time choice nodes; audio selection list menus; fullscreen tools Nothing is sent to a server, so there's no upload delay and no privacy trade-off.
