The verdict

Grammarly wins, 8.3 to 5.8

Wordtune's Advanced plan is $13.99 a month, well under Grammarly Pro's $30. For that lower price Wordtune drops several things Grammarly includes: plagiarism checking, AI-text detection, a saved style guide and a personal dictionary. Grammarly holds SOC 2 Type II and ISO 27001 certification; Wordtune's privacy policies mention neither. Wordtune's mobile keyboard works on iOS only; Grammarly's phone keyboard listing carries no such limit.

Pick Grammarly if you want plagiarism checks, AI detection and certified security.

Pick Wordtune if you want a cheap rewriting tool and don't need detection.
