Files stay with you.
The actual file processing happens in your browser. A small number of advanced tools may load a browser helper library, but OutMonkey does not upload your file to do the job.

OutMonkey is built to be simple enough for someone doing this once and useful enough for someone who does it every day.
What this tool is for
Ideal line length checker
Check text measure by character count. The aim is a useful result without making you learn a full piece of software first.
Good to know
Treat the maths as a starting point.
Look at the result at the size it will really be used. Fonts have different proportions, so spacing that is mathematically neat can still look too tight or too loose.
A checker tells you what it can measure; it does not replace a final human look. Use the result to make the next decision, not as a guarantee.
In plain English
You do not need to be an expert.
Designers can use the numbers as a fast baseline. Everyone else can simply compare the previews and choose the version that is easiest to read and looks balanced.
Type maths gives you structure; the final judgment should still be optical.
