ความเห็นบรรณาธิการ
Here's what nobody tells you: these aren't competitors. I use Claude to write my first drafts and Grammarly to catch the typos before I hit send. It's like having a co-writer AND a proofreader. If I could only pick one, I'd pick Claude — writing quality matters more than grammar corrections you can do yourself.
