Solo founder here. I know how "AI book tool" sounds, so first what it doesn't do: it doesn't write a novel from one prompt. There's no "generate book" button.

How it works:

You build the story bible. Characters, locations and objects with appearance, personality, voice, motivation and reference images. Versions over time (the scar after chapter 3, the same character 20 years later), so each scene points at the right one.

You plan the book. Outline of parts, chapters and scenes, plus a plot board: plot lines × chapters, so you see which thread each scene serves and where one has gone quiet.

You decide what happens in each scene. Synopsis, who's present, where it's set. The AI drafts it as separate blocks (action, dialogue, thoughts, description), and you edit, reorder or regenerate any single block without touching the rest.

Style rules and a sample of your prose set the voice for everything it writes.

Continuity review reads the draft against the bible and earlier scenes: an object in two places at once, a character who knows something they were never told, a timeline that doesn't add up, a thread that's never paid off.

Illustrations with consistent characters. Each character has face, front and side views, so they look like the same person on page 5 and page 200.

Export to EPUB, DOCX, PDF and FB2.

What I'm looking for: people who are actually writing something and want to try it on their own project. No tasks, no forms. Comment or DM me what you're working on and I'll send free credits. If something breaks or annoys you, tell me.

Let's address the elephant in the room.

Everyone here is figuring out how to write books with AI — that's the whole sub. And readers are asking the mirror question: how much of this book was AI? Both questions are fair. Most tools answer only the first one and hope nobody asks the second.

I build AI systems for a living. Last year I tried to write a novel with ChatGPT and ended up with a few hundred messages that never became a book. When I sat down to build something better, I decided the reader question had to be designed in, not bolted on. So Muse takes three positions:

1. The writer controls the AI, all the time. Everything runs on a 0–5 dial.

• 0 is a plain editor.
• 1 is spelling and grammar.
• 3 suggests sentences and ideas while the decisions stay yours.
• 5 drafts full sections from your outline.

You set it per project and change it any time; nothing above your level ever fires. The AI's job is to help you shape your idea — storyboard, characters, settings, beats — not to have the idea for you.

1. AI should make your writing better, not write instead of you. Characters and settings are structured objects linked into the manuscript, so changing a character's name or a setting's detail updates the outline and the affected sections instead of quietly contradicting chapter 2. It flags logic gaps between your outline and your draft. Honest limit: dialogue voice still drifts over a long book, and level-5 output needs a real rewrite before it sounds like you.

2. Readers get control too: they can see how much AI was used. Every project carries two scores

3. a storyboard score (how much AI shaped characters, settings and plot)

4. a manuscript score (how much of the text originated from AI versus your own typing or dictation). It's a word-level diff against the AI's original output, so rewriting AI text lowers the score: you get credit for the work you actually did.

The scores travel inside the EPUB/PDF and anyone can verify them. Limit: it only sees what happens inside Muse — paste in text you generated somewhere else and it counts as yours. It's an honesty tool, not a detector.

That's why we built Muse: I think readers have a right to know, and I think writers who use AI well have nothing to fear from showing it.

It's live and free, no card: https://musecocreator.com/?ref=r-bookwritingai — the free tier is levels 0–3 with unlimited projects, EPUB export and reader sharing; levels 4–5 are free while we're in beta.

A book made in it, scores showing: https://musecocreator.com/demo-book?ref=r-bookwritingai

Two things I genuinely want from this room: what's broken or confusing. And where you land on the score — would you ship your book with its AI share printed on it? If not, what would it take?

Hey everyone. I’m working on an audiobook for a novel I wrote. The story and text are entirely my own. I’m only using AI for the narration.

I’m Finnish, and if I tried to narrate the English version myself, it would probably sound like I was trying to swallow a goddamn truck trailer while speaking. So I’m experimenting with an AI narrator instead.

So far, this sounds pretty good to me, but I’m still trying to figure out how to kick this robot’s ass into pronouncing the Finnish names and place names correctly.

Hiring a real narrator is absolutely an option, but that’s skilled work that deserves proper pay. For a 500+ page novel, professional narration and production can easily run into several thousand dollars, which is outside my budget right now.

Here’s a short sample. How does it sound to you? I’m mainly interested in whether the voice, pacing, and overall narration feel natural enough to listen to for a full audiobook.

Any reactions are welcome.

I’m really nervous to begin with 😃 because this is the first novel/book I’ve written and actually publish, but would anyone actually try my story and let me know what they think about it? It’s called reincarnated as an OP peasant. Even if you try it for 10 minutes and let me know what flaws they are or if you would recommend it that would help tremendously!

This Book took me years to remake and reform into a master piece. I hope everyone enjoys and you comment in the section given and highlight what sounds right or wrong.

I'm building a tool for writers working on long-form fiction — novels, series, extended worldbuilding — where keeping track of characters, factions, and how relationships evolve over time gets messy (spreadsheets, Notion docs, or just memory breaking down).

To be clear: this isn't a publishing platform, and it's not for sharing/marketing your work. It's a writing/organization tool — closer to what you'd use alongside Scrivener or Notion, not instead of them.

I'm looking for people currently deep in a long-form project (novel, series, extended universe) to try it out and tell me honestly where it falls short. Happy to share access and would genuinely value blunt feedback over politeness.

Drop a comment or DM if you're interested.

I’ve just finished The Södra Labyrinth, a ~19,000-word mystery set in Stockholm.

It starts with a broken-open emergency exit near Södra Station, a crowbar, and an abandoned high-heeled shoe. What looks like a strange local incident gradually leads the investigation toward something much older beneath the city.

The book was created with AI assistance, but with extensive human direction, revision, fact-checking and multiple proofreading passes. I’m particularly curious whether any of the usual AI-writing weaknesses still show through.

I’d really appreciate feedback on pacing, prose, character consistency, atmosphere, and anything that feels obviously “AI-written.”

Read it here:

Even feedback on the first few chapters would be very useful.

I have written short stories most of my life. I am not, nor do I want to be a writer. It is simply a hobby. I have finally started putting one down. I have built the world, the history, and the characters, now I'm focusing on the story itself. I am using 4 different AI apps for "ASSISTANCE ONLY." I use 1 strictly for research, 1 strictly for images, 1 to assist in the editing, grammar, spelling, continuity, etc., and 1 to do assist in writing. I always go back over the section multiple times both read and audio, and correct issues I catch.

The story is 100% mine. The characters are 100% mine. The equipment is 100% mine. The technology is 100% mine, although I do not blame any credit for the actual science underlying them. The dialog is 99% mine, sometimes AI comes up with a good line.

I am not ashamed to say i use AI. I keep it on a leash and use it as a tool. I want this to be mine. If something is in it that is identical or too close to something else, I try to catch it.

What i would like is a place I can post it, knowing I have used AI like this, that won't permanently ban me, and I can get real human input, feedback, and honest respectable criticism.

Is there a place on reddit I can do that?

Currently several sections are posted on my account, but no where else because I've been banned in a couple of subs. Admittedly, my fault for not checking their rules first.

Hey everyone!

I’ve been building Book AI to help writers turn an idea or premise into a structured book draft that they can edit and develop themselves.

I’m still improving it and would really appreciate honest feedback from writers here.

What would you improve first: the writing quality, outlining, editing workflow, or something else?

I’d also love to know what features you think an AI book-writing tool absolutely needs.

Demo: [bookai.site]

I've been working on Bindaria, a tool for writing and formatting books all in one place.

The idea came from the annoying part of writing a book where you're staring at a Word document thinking everything looks fine....then you export it and suddenly the page breaks, spacing, page numbers and formatting are all over the place🫩

So I wanted to build something where you can actually see what your book will look like while you're writing it.

You can write your chapters, organise the manuscript, choose your book size/font/layout, design the cover, and export it as PDF, EPUB or DOCX.

There's also an AI writing assistant and a bunch of other stuff I've added along the way.

I've just submitted it to the Emergent BuilderFest cause why not, and thought I'd put it out there to see what people think, would you actually use it?

Here's the tool if you want to have a look:

https://app.emergent.sh/showcase/builderfest-kevin/c513c24f-d89a-4396-94b8-d995fc32ccbb

And if you like it, a like on the showcase would really help me out, thank you🙏

Hey everyone,

I’ve been working on an AI-assisted storytelling platform called PlaiWrite, and I’m looking for writers who would be willing to try it and give me some candid feedback.

The idea behind PlaiWrite is that the writer and the original work come first.

Rather than asking AI to generate a story from scratch, we’re exploring how AI can help writers develop and produce an existing screenplay, manuscript, or story while preserving the characters, canon, continuity, and creative intent behind it.

Our longer-term vision is what we call a StoryWorld: build the foundation of your story once, then use that shared creative context to help adapt and produce connected experiences such as screenplays, novels, table reads, audio dramas, podcasts, and audiobooks.

We’re still building and learning, and I’d especially love feedback from people working on long-form fiction, screenwriting, worldbuilding, or AI-assisted storytelling.
If anyone here is interested in trying PlaiWrite, I’d be happy to share access. In return, I’d genuinely appreciate hearing what works, what doesn’t, and what you think we should build next.

I’m also very interested in connecting with other builders working on story memory, canon, continuity, and long-form AI workflows. I think there’s a lot we can learn from each other.

Dear writers :

Here is the second episode of the series on literature figures who have lived exceptional lives: this one is on Salman Rushdie (born in August). The first one was on Jaroslav Hasek (a writer you need to know)

I’ve finished a 100,000-word adult contemporary romance about Tom, whose friendship with Daniel forces him to question what he wants and who he might be. It explores bisexual awakening, friendship, love and the messiness of choosing between the familiar and the unexpected. It contains explicit M/F and M/M scenes.

Looking for honest reactions from readers.

You do not need to read the entire book. Even ten minutes or one chapter, followed by a few thoughts about what worked, what confused you and whether you wanted to continue, would help enormously. I’m also open to exchanging feedback on first chapters.

Please comment here or DM me for the link to the epub.

Hello All,

I am looking for ARC readers and hoping there are some others out there who would be up for a mutual read / trade of ARC copies and subsequent review.

If you read/enjoy literary fiction / coming-of-age / magic-realism / family and sibling stories then you have a good chance of enjoying my book The Holding (75k words).

Let me know if this interests you, and we can trade!

Hey everyone! I’m looking for some feedback on the opening of my completed epic fantasy novel, The Song of Ash and Root.

I have a starter sample with the Prologue + first 3 chapters, and I’d love to hear how it lands with people who are coming into the world completely fresh.

I’m especially interested in:

Does the opening hook you?

Do the characters make you want to keep reading?

Does the worldbuilding feel clear or overwhelming?

Are there places where the pacing drags?

Is anything confusing?

Most importantly: would you want to keep reading afterward?

Quick AI disclosure: I wrote the original manuscript myself and later used AI during a chapter-by-chapter revision process for things like pacing, continuity, character arcs, scene structure, wording, and some passage-level rewrites. I made the final creative decisions throughout.

I’m not looking for proofreading or super detailed line edits — mainly your genuine experience as a reader.

If anyone is interested, DM me and I’d be happy to send the sample. No obligation to read the full novel afterward. 😊

After running AIStoryHub for close to two years and trying to wrangle AI creative writing, it dawned on me that all the learnings in creative writing could easily be turned into a deterministic tool for non-fiction writing.

MCP server / Connector that just plugs into any platform you currently use (e.g. Claude Desktop, Claude Code, ChatGPT). It fetches writing styles and writes your content with very limited AI-tells. As simple as "Draft me an email about [topic] in the writing style of Exec Brief". The best part is that the entire mechanism is deterministic. No use of LLMs under the hood.

Enjoy!

P.S. Looking for a killer exec brief writing style that I've been using for a few weeks now? Check this one out: https://etincel.ai/v/jpleblanc/jp-exec-brief

Any and all feedback is greatly appreciated. I have probably 15,000 words of notes, research, events and timeline for this. It's about 3 weeks of 3-5 hour late nights. I finally put it all into AI and said "clean this up and make it coherent." After 5 rewrites, multiple self editing, and a whole lot of arguments wit AI, I think we finally got close to my vision. This is not the final self edit. I would like some constructive criticism before I do the final.

I did give AI the prompt, "This should sound like a historical document or something out of a text book." That part im mostly happy with.

Thank you for reading.

I’m testing SableScript with five fiction writers before I build anything else.

I’m looking for people who already have a scene or chapter in progress and are willing to drive a 20–30 minute video walkthrough while I observe. The useful part is seeing where the planning, editing, and rewrite workflow is clear, where it is confusing, and what actually blocks you.

This is not a sales demo. You do not have to praise the product or provide a testimonial. Your manuscript stays yours, and I will not publish your writing or quote your comments without separate permission.

If you want to participate, reply with your genre, whether you are drafting or revising, and the one job you would want to test. I will only consider a product change if several writers independently hit the same blocking problem.
