Paste a text and see the reading time, the Flesch readability score and stats like words, sentences and syllables, in real time.
This tool combines two metrics that are useful to writers. The first is reading time, estimated from the word count and an adjustable average speed (200 words per minute by default for silent reading, and around 130 for reading aloud). The second is readability via the Flesch score: in English we use Flesch Reading Ease and in Portuguese its Brazilian-Portuguese adaptation, both based on average words per sentence and syllables per word. The higher the score (0 to 100), the easier the text. We also show the approximate grade level (Flesch–Kincaid) and full statistics, words, characters, sentences, paragraphs and syllables. Everything is computed live in the browser, ideal for tuning blog posts, essays and study material before publishing.
Paste the code into your HTML and the tool shows up on your page, without J-Kit's navigation and ads. It still runs in the browser of whoever visits your site.

We divide the word count by the chosen reading speed (200 words per minute by default). You can adjust that speed with the slider. Speaking time uses a lower speed (about 130 wpm), typical of narration and presentations.
Complex text with long sentences and difficult vocabulary; consider simplifying.
