## Summary

Hemingway color-codes hard-to-read sentences, adverbs and passive voice and shows a reading grade level, which helps tighten nonfiction and children's books. The free web editor and the one-time desktop app do not include AI; the Hemingway Editor Plus subscription adds AI rewrites and grammar fixes. It is a style checker, not a full proofreader or formatter. AI rewrites of your own text count as AI-assisted under KDP rules and need no disclosure.

## Pros

- Free web version needs no account

## Cons
