🔒 Everything runs 100% in your browser. Your files and input are never uploaded to any server.
Analyze pasted text—sentence count, word count, average sentence length, and more—to show a quick readability score out of 100 and a grade. It lets you see in numbers whether your sentences run too long or too hard, helping anyone polish a blog post, article, or report to read more easily.
How to use
- Paste the text you want to analyze into the input box.
- Check the readability score out of 100 and the 'Easy / Moderate / Hard' grade.
- Review detailed metrics like character count, word count, sentence count, and average words per sentence.
- If you get a warning that words per sentence is high, split the long sentences and re-analyze to compare.
FAQ
- Is the text I enter sent to a server?
- No. Text analysis and score calculation all happen only in your browser. What you enter is never transmitted or stored anywhere, so you can safely paste drafts or private writing.
- How is the readability score calculated?
- It's based on the average number of words per sentence and the average characters per word. The shorter and more concise your sentences and words, the higher the score, shown across five grades from very easy to very hard.
- Is this score the same as international standards like Flesch?
- No. Metrics like the Flesch index are designed around English syllable structure and don't map perfectly to every language. This tool is a simplified metric best used to compare your writing before and after edits rather than as an absolute benchmark.
