Our verdict

Pick a tone in Writetone and the extension rewrites phrasing to match it, scanning keywords in the document to keep that tone consistent from start to finish. Favorite tones can be saved so a writer is not resetting preferences every session. The available presets are built for common writing situations, so anything unconventional or highly specific tends to need manual polishing afterward. There is no cost beyond installing the free extension.
