Could AI help you revise a novel without writing a word?

As November brings a fresh wave of novel-writing, a British startup is making the case for AI as a manuscript analyst: a tool to help writers spot structural problems and decide how to fix them.

For many novelists, finishing a first draft is only the beginning. 

The next challenge is working out whether the story holds together, where it loses momentum and what needs attention before readers see it.

That kind of close structural reading is the work of a developmental editor. It can also be costly, putting professional feedback out of reach for some writers.

Novel Maestro, a British startup launching on First November, wants to make this stage of revision more accessible. Its software analyses a manuscript’s structure, characters, scenes, subplots and pacing. It does not write or rewrite the novel.

“Everyone is arguing about whether a machine should write your novel,” founder Timothy Large told Be That Writer.

“Personally, I don’t think it should. But far less attention goes to the promise of using AI to analyse thousands of details across a manuscript simultaneously, to help the writer see the precise shape and dynamics of their story, and fix what’s wrong. Think of it as an MRI for your manuscript.”

The service was beta-tested with over  30 writers across Britain, Canada, the United States and Australia.

The cost of a structural edit

Developmental editing looks at the big-picture elements of a novel: its structure, character arcs, pacing and cause and effect. It takes time, and the cost reflects that.

The Chartered Institute of Editing and Proofreading’s suggested minimum rate for development editing is £42.66 an hour. Using editing speeds reported for fiction developmental editing in the US Editorial Freelancers Association’s 2026 rate chart, an 80,000-word novel could cost roughly £1,370 to £2,480 to edit. This is an illustrative calculation, not a surveyed UK price range, and does not include copyediting or proofreading.

Many independent authors spend much less. In Written Word Media’s 2024 survey of more than 1,500 authors, nearly a third said they paid nothing for editing. Its 2025 survey of 1,346 authors found that only a small minority spent more than US$2,000 (about £1,500) editing a book.

That does not tell us how many novels go without structural feedback: writers may receive useful comments from readers, writing groups or other sources. But the figures do point to a gap between professional editing rates and many authors’ budgets.

“The structural edit is where a writer gets to ask the big questions about a book,” Large says. “Too many never get that chance. We built Novel Maestro to do the deep reading, show the evidence, inspire revision ideas. It actually creates more work for the author, because the edit is on them.”

After the November draft

The challenge of writing 50,000 words in 30 days outlived NaNoWriMo, the US nonprofit that helped hundreds of thousands of people take on the challenge. The organisation closed in 2025 after a turbulent period that included a dispute over its position on generative AI.

For writers who take part in NaNo2.0, or set themselves a similar goal, reaching the end of a draft can bring a new question: what now?

“The first achievement is getting the words down,” Large says. “Then come the harder questions. Does the story hold together? Where does it lose the reader? What should I change first? Writers deserve something more useful than ‘the middle drags’ and something more affordable than a bill for thousands.”

AI as an analyst

Much of the debate about AI and fiction has focused on machines writing books: what material was used to train them, whether AI-generated titles will crowd out human writers, and whether readers should be told when a book was created with AI.

A 2025 University of Cambridge survey of 258 published UK novelists found that 97% felt extremely negative about AI writing whole novels. Views on AI editing were more varied: 43% felt extremely negative about AI editing their text, while around 8% already used it in that way.

Novel Maestro’s approach is to analyse a manuscript against principles of storytelling craft, without generating or rewriting prose. It assesses whether a story holds together, whether characters drive events and whether the ending delivers on the promises made at the beginning. The writer decides whether its reading is right and what to do next.

The company says the tool maps a manuscript scene by scene, running around 175 analytical passes and 14 whole-book diagnostics. It covers 106 genres grouped into eight families, and has no word limit.

Authors begin by describing the book they intend to write. They can then correct the software’s initial understanding before it examines how the manuscript matches that intention.

The aim is to trace problems back to their causes. A sagging middle, for example, might be linked to a protagonist who has stopped making decisions. An ending that feels unconvincing might reflect a promise in the opening that was never developed. Several apparent character problems could have their roots in one relationship.

The analysis also looks for what is working, so writers can consider what a revision should preserve.

“Criticism is only useful if the critic understands what the work is trying to do,” Large says. “The question is whether a choice serves this book, not whether it follows somebody else’s template.”

Findings writers can inspect

Novel Maestro says its findings are tied to passages and scenes in the manuscript. Interactive charts show patterns in areas such as character agency, stakes and subplots, giving writers evidence to examine and question.

Its “Ask Maestro” chat feature lets writers query a finding or explore possible ways to address it. They can turn revision priorities into tasks pinned to the margin of the built-in text editor, or export reports to use with other writing tools.

When a writer submits a revised manuscript, the software reads the whole book again to assess whether issues have improved, disappeared or surfaced elsewhere.

“A finding that your protagonist stops making decisions is the start of a conversation,” Large says. “Is that a weakness, or exactly what this book needs? The writer still has to make that judgement. Our job is to give them a clearer view of the book they are judging.”

Novel Maestro says its staff do not read users’ manuscripts. If a support issue requires someone to see the text, the company asks the writer to provide the relevant passage. It uses Google’s paid Gemini API and Anthropic’s commercial API, and says manuscripts submitted for analysis are not used to train those providers’ models.

Price and availability

Novel Maestro is available at novelmaestro.com. Writers can start with Maestro’s First Take, a free reading of their entire manuscript.

The Full Maestro costs £59 for three deep reads of one novel, with no subscription or time limit. Additional reads cost £15 each. The price includes an in-depth developmental report, feedback from six beta-reader personas, 14 interactive diagnostics with charts and analysis, and access to the smart text editor.

Gift certificates are available. The interface is in English, though the tool can analyse manuscripts in any language.

Novel Maestro is operated by Large & Stoker Ltd, registered in England and Wales under company number 17448669.
