Grammarly remains a strong tool for real-time grammar and style checking, especially in keyboard mode. However, AI rephrasing often distorts meaning, and the aggressive paywall is frustrating.
評価点：Keyboard mode works directly in any app and highlights errors immediately.
不満点：AI tone-reframing changes the meaning of what you wrote instead of improving the form.
向いている人：Native speakers who need a quick grammar checker
Wordtune was a useful keyboard paraphrasing tool, but after the 2024 redesign the core feature became unstable or disappeared entirely. Paying users are complaining broadly about a regression in suggestion quality.
評価点：Rephrasing variations directly in the keyboard without switching apps.
不満点：After the update the model picks worse suggestions than it did a year ago.
向いている人：People who write a lot in messaging apps and want to quickly improve their tone
Claude as a model is highly regarded for reasoning quality and writing assistance, but the mobile app is regularly criticized for instability, crashes, and poor support. The product is stronger on the web.
評価点：The quality of responses on text and nuance of phrasing is above most competitors.
不満点：The mobile app frequently freezes, loses chats, and is not adapted for assistive technologies.
向いている人：Writers and developers who work through a browser
OpenAI's flagship AI assistant with broad capabilities for editing, rewriting, and structuring text. The main weakness: the model hallucinates on facts and loses context in long sessions.
評価点：Handles complex editing and style requests faster and more accurately than a search engine.
不満点：Memory between sessions is inconsistent and sometimes mixes another conversation's context into the current one.
向いている人：Anyone who writes regularly and wants a general-purpose AI assistant
QuillBot genuinely helps with paraphrasing and improving text, especially for non-native speakers. After recent updates, the quality of a second round of editing has degraded, and the free mode has become nearly worthless.
評価点：Natively paraphrases and finds better word choices so that text sounds more polished and precise.
不満点：A second round of editing often merges words and breaks sentences that were already correct.
向いている人：Non-native speakers writing in English
