This is the August 2026 edition of the LLM Readability Score benchmarks. Every figure below comes only from scans run inside that month, and none of them will change again — a rate you quote today will still be at this address years from now. For the current picture, go back to the tool's own page: that one is refreshed at every revision, and this one never is.
How the scores fell
This is how 1,002 scans spread across the five score bands in August 2026. A large group clears the top band while a real tail is left behind, so the median understates how well the leading pages do.
