本当の違い
Both offer free tiers, so the real question is what you get when you start paying.
Copy.ai stands out with 90+ copywriting templates and Workflow automations. Grammarly counters with Real-time grammar, spelling, and punctuation corrections and Tone detection and rewrite suggestions.
Copy.ai's Achilles heel: output quality is inconsistent — great for first drafts but you'll spend time editing, especially for long-form. Grammarly's: suggestions can be overly conservative and strip personality from your writing if you accept everything blindly. Pick whichever weakness you can live with.
結論
If you value 90+ copywriting templates and メール、広告、sns投稿など — 深く考えずにサクッとコピーが欲しいセールス/マーケティングチーム向け, go with Copy.ai. If メール・ドキュメント・投稿を書く全ての人向け — どこでもミスをキャッチする常時オンのセーフティネット matters more, Grammarly is your pick. Neither is a bad choice — but one will fit your workflow better.
