Frequently asked questions
Does this use an external API?

Are the results guaranteed?
No. Estimates depend on your inputs and assumptions. Review all output before using it for a real campaign, official application, or publication.
Are my inputs uploaded?
Text input for these client-side tools is not sent to the website server for processing. Image and video processing happens on your device in this browser when supported.
