Readscore

A readability checker for any web page. Instantly view the reading level, readability score, and text complexity.

ReadScore is a Chrome extension that analyzes the readability of English web pages using transparent, rule-based criteria. It works entirely within your browser and requires no installation.

The extension calculates readability scores and reading levels using standard formulas like Flesch-Kincaid and utilizes text statistics such as sentence length and word complexity. This helps you understand how easy or difficult a text is to read.

You can also highlight structural readability issues directly on the page, including complex sentences and dense paragraphs.

All analyses run locally in your browser. There are no AI models, external APIs, tracking, or data collection.
