Readability checker for clear, scannable writing

This readability checker scores your text with the Flesch reading-ease formula, estimates the grade level, and highlights the long or dense sentences that lose readers on a fast-scrolling feed. Aim for short, plain sentences: on LinkedIn, writing that reads at an eighth-grade level or below keeps people moving through your post. It runs in your browser, nothing is uploaded.

What is the readability checker?

Readability measures how much effort your writing takes to read. The Flesch reading-ease score (0 to 100, higher is easier) and its grade-level companion are the standard, computed from sentence length and syllables per word. On social feeds, lower grade levels win: short sentences and plain words get read to the end. This tool scores yours and shows which sentences to cut down.
