Ginger runs sentence-level context analysis rather than word-by-word flagging, which means it catches 'their' where you meant 'there' in a clause that a basic spell-checker would pass. The rephraser surfaces alternative constructions for wordy or awkward sentences — useful for ESL writers who know something reads wrong but cannot identify the fix. It operates across Chrome, Edge, Word, desktop apps, iOS, and Android, so correction happens in the surface where you are already writing. The free tier exists but the features that matter for extended professional use are paid-only. For anything beyond basic grammar and rephrasing — style scoring, advanced vocabulary coaching, substantive prose feedback — you are outside what Ginger covers.
