Grammarly is a well-known program for Windows that comes with a writing assistant. Known for grammar, spelling, style, tone and plagiarism checks across many desktop and web applications, including Firefox, Chrome and Opera.
Real time
It is possible to monitor text input fields and highlight potential errors as they are typed. Underlines appear for grammar, punctuation, clarity and stylistic issues, supporting immediate correction. Users can click suggestions to accept or ignore them, or view explanations to learn why a change is proposed.
Suggestions and AI
Beyond basic correctness, there are suggestions that improve clarity, tone, engagement and formality depending on your writing context. A tone detector expresses how your texts may come across friendly or formal. For longer passages, the app may propose full-paragraph rewrites or alternative phrasings to help vary structure.
In higher tiers, the tool checks your text against a large database to identify potential plagiarism and missing citations. A quotation generator assists in forming APA, MLA or Chicago style references automatically. Generative AI features allow you to draft or expand text, create outlines, or propose reworded segments.
