Frequently asked questions

How does the tool define a sentence?

A sentence is defined as a sequence of characters ending with a period (.), exclamation mark (!), or question mark (?), followed by whitespace, a newline, or the end of the text. Common abbreviations like "e.g." or "Mr." are handled to prevent false positives.

Is my text sent to any server for analysis?

No. Just like all tools on Lowkeydevs, the Sentence Counter processes your text entirely client-side. Your text never leaves your browser, ensuring complete privacy.

How is the Reading Time calculated?

Reading time is calculated based on an average adult reading speed of 225 words per minute (WPM). The formula simply divides the total word count by 225.
