Frequently Asked Questions

Is my text saved or stored?
No. All processing happens entirely in your browser. Your text is never sent to any server or stored anywhere. It's completely private.
How accurate is the sentence counter?
Very accurate. The tool uses smart detection to handle abbreviations (Dr., Mr., etc.), decimals (3.14), and complex punctuation correctly. It recognizes periods, exclamation marks, and question marks as sentence endings.
What's the ideal sentence length?
For general audiences, aim for 15-20 words per sentence on average. Academic writing can be longer (20-25 words), while casual content works better with shorter sentences (10-15 words).
Does it work with other languages?
Yes, the sentence counter works with any language that uses periods, exclamation marks, or question marks as sentence delimiters. Results are most accurate for Latin-script languages.
Can it detect run-on sentences?
While it doesn't explicitly flag run-on sentences, you can identify them by checking average sentence length. Sentences significantly longer than your average may be run-ons that need splitting.
Can I save my sentence count?
The tool provides real-time analysis but doesn't save results. You can copy your text or take a screenshot of your statistics for future reference.
