AI Reading Level Checker
AICheck the reading difficulty and grade level of any text.
Frequently asked questions
What metrics does it report?
An estimated grade level, a Flesch-Kincaid estimate, the likely target audience, average sentence length, the percentage of complex words, and 3 specific suggestions to improve readability.
Is the Flesch-Kincaid score exact?
It's an AI-generated estimate, not a precise formula calculation — for an exact score, a dedicated readability formula tool would be more reliable, but this gives a good directional read plus actionable suggestions.
How long should the text I paste be?
A paragraph or more gives the most reliable estimate — very short snippets (a single sentence) don't give the model enough signal to judge sentence variety and complexity.
