Grammarly AI (GrammarlyGO)
Best overallGrammarly AI wins for anyone who needs an all-in-one writing assistant that works everywhere—email, docs, social media—with tone shifting, proofreading, and AI detection. ParaphraseApp is a simpler, cheaper choice if your main job is rewording text to avoid AI detection or change style, but it lacks Grammarly's breadth. The single biggest difference: Grammarly is a full writing copilot; ParaphraseApp is a focused paraphrasing tool.

Common questions
Yes, Grammarly is better because it rewrites while also fixing grammar and adjusting tone, and it works directly inside Gmail and Outlook. ParaphraseApp only rewrites and you'd have to copy-paste back and forth.
Yes, that's one of its main strengths. It's designed to rephrase text so it sounds more human and less like ChatGPT wrote it. Grammarly's AI Detector does the opposite—it spots AI-written text.
ParaphraseApp is slightly easier—just open the website and paste text. Grammarly requires installing a browser extension or desktop app and signing up, but the setup is still quick and guided.
Grammarly's free tier gives you solid grammar and clarity suggestions. ParaphraseApp's free version is very limited (only 1,000 words per session with ads). For serious use, you'll likely need to pay for ParaphraseApp.
Grammarly has a mobile keyboard app for iOS and Android, so you can use it in any app. ParaphraseApp does not have a mobile app—you'd have to use it in a mobile browser, which is clunky.
Grammarly is the versatile daily driver for all your writing; ParaphraseApp is the affordable specialist for rewording text.
If you write a lot and want one tool that checks grammar, adjusts tone, and rewrites text everywhere you type, go with Grammarly—its free tier alone is worth it. If your only need is to rephrase paragraphs quickly and cheaply, especially to sound less like AI, ParaphraseApp is a solid, simple choice. For most people, Grammarly is the better daily companion.
