The verdict

Wordtune wins, 5.8 to 5.5

Wordtune writes new text from a prompt and offers a phone keyboard on iOS; LanguageTool does neither, focused instead on checking text you already have. LanguageTool includes an API and a personal dictionary, both missing from Wordtune's known facts. Wordtune's Advanced plan is $13.99 a month, well under LanguageTool Premium's $25.48. LanguageTool states it does not train its AI on your writing at all, while Wordtune lets users opt out but defaults training on.

Pick LanguageTool if you want an API, personal dictionary and no AI training.

Pick Wordtune if you want text generation and a phone keyboard at a lower price.
