The app delivers real value for essays and legal documents, but trial period behavior raises questions and the editor has no version history. The product works, but clearly falls short of web-based ChatGPT.
評価点：Helps structure and rephrase drafts, especially for academic texts.
不満点：No version history: one undo button rolls back all edits at once.
向いている人：Students who need to quickly improve an essay draft
The app genuinely helps with essays and business letters at a basic level, but a request limit under an unlimited subscription and a clunky onboarding undermine trust. Real value is there but buried under opaque terms.
評価点：Helps put thoughts into words when nothing comes, especially for formal and business texts.
不満点：The unlimited subscription actually has a hidden rate limit with forced pauses between requests.
向いている人：Students and professionals who occasionally need a letter or essay draft
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
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
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
