Grammarly vs QuillBot vs Wordtune
Improving text you have already written, rather than generating it. These overlap heavily, so this is about which failure you care about.

Which should you pick?
Grammarly is the broadest and the one that catches actual errors most reliably, and it is everywhere you type. QuillBot is built around paraphrasing and is the strongest at genuinely restructuring a sentence rather than correcting it. Wordtune sits between the two and is good at offering alternative phrasings you would not have reached for, but check it is still being developed before you commit: it is still on sale while AI21 has reportedly moved on. If you want correctness pick Grammarly, if you want to say the same thing differently pick QuillBot.
