What is Manuscript Polish?
A proofreader for serious writers.
Manuscript Polish is an AI-assisted proofreading service built for novelists, screenwriters, and long-form writers who care about voice as much as correctness. It corrects grammar, spelling, punctuation, style, tone, and format-specific issues — without flattening the way you write.
Powered by both OpenAI GPT-5.2 and Gemini 3 Pro, the tool understands the difference between literary fiction and a thriller, between a children's picture book and a documentary screenplay. Pick a genre preset, choose a priority level, and your manuscript receives the right kind of attention.
Every correction is highlighted side-by-side so you can see exactly what changed before you accept it. Your downloaded file is always clean — no markup, no annotations, just the corrected version of your work.

About the Creator
Keith Williams
Novelist · Songwriter · Founder
Writing has been a major part of my life for decades. As both an author and songwriter, I understand the excitement, challenges, and dedication that go into creating original work.
I have completed four novels, including Continuum, a two-part sci-fi thriller. While science fiction is one of my passions, my writing experience spans multiple genres, including drama, comedy, romance, suspense, and thriller fiction.
Alongside novel writing, I have spent more than forty years writing songs across a wide range of styles, including Hip Hop, Rap, Pop, R&B, Soul, and Rock. Working across different creative disciplines has given me a deep appreciation for storytelling, structure, pacing, character development, and the importance of finding the right voice for your audience.
Manuscript Polish was created because I saw a gap in the services available to writers. Too often, proofreading and manuscript reviews focus only on surface-level corrections. I wanted to create a service that looks deeper.
By allowing writers to select the genre of their manuscript before the review begins, Manuscript Polish can provide more focused and relevant feedback, helping writers strengthen not only grammar and presentation, but also the elements that matter most within their chosen genre.
The same philosophy inspired our Song Lyric Analysis service. As a songwriter myself, I have always been interested in understanding how others interpret my work. Detailed lyric analysis can highlight strengths, themes, patterns, and opportunities for improvement while helping creators recognise what is already working well.
My goal is simple: to help writers and songwriters present their work at its very best while preserving their unique voice and creative vision.
Thank you for visiting Manuscript Polish. I look forward to being part of your creative journey.
