**限制:** Pro pricing is on the higher side compared with some general-purpose writing tools; Free tier is capped at 5 uses a day and 1,000 characters; Best experience depends on installing the keyboard or browser extension; Enterprise features require contacting sales

**優勢:** Works directly inside any website's text fields, no copy-paste required; Covers grammar, conciseness, tone, translation, and emoji in one menu; Fast, one-click improvements suited to short-form and social writing; Lightweight browser extension with a simple learning curve

**限制:** Requires installing a Chrome extension before most features work; No dedicated desktop or mobile app; Feature set is narrower than full document editors like Google Docs add-ons; Grammar and rewrite quality can miss nuanced or technical language
