Write the whole novelwithout losing the thread.

Your story bible is a click from the page, and a continuity check warns you when someone who died in chapter four walks back in. When the last scene is done, Onwarder makes the ebook and the paperback interior.

Chapter 19, first draft

The innkeeper looked up from the bar and smiled. Hesper reached for his usual cup before he had finished crossing the room. “Back so soon,” she said.

Possible contradiction. Your notes say Hesper died in chapter 4, and the inn burned down with her.

Your revision

Half the roof was open sky. Kaelen set two coins down on what was left of the bar, the way Hesper would have made him, and nobody came to take them.

Story bible

Hesper

Innkeeper, The Salted Crow

Status: Deceased
Recorded: Chapter 4, The Salted Crow burns
Known by: Kaelen, Fitz, the Ashfall guard
Place: Ruin, Ashfall Row

Try it: write a line that brings Hesper back, and a demo check flags it. This needs JavaScript, which is off or has not loaded.

Try it: bring a dead character back. Write the next line.

A demo of how a continuity check works, with the two facts on Hesper's card: it only looks for Hesper acting alive or the inn still trading. The real check compares a scene with the facts you recorded.

An illustrative continuity check. It flags; you choose the words.

Before you choose a tool

Every writer of a long book has one of these stories.

Six problems writers describe again and again, in their own words from public Reddit threads, and what Onwarder does about each. None of these writers are talking about Onwarder.

Lost work and sync disasters

A laptop dies, a cloud folder conflicts, a file will not open, and a year of a book is gone.

I used to use scrivener, but my last pc fried and I lost everything. I should have had a backup but I didn’t.

A writer on r/fantasywriters, September 2025

I have lost everything at one point, and it forced me to rewrite a book. Which turned out better than the first time

A writer on r/writing, November 2025

What Onwarder does

Onwarder saves as you type, on your device, with no account, and saves your whole library to one file whenever you like. With Cloud, every book you write is backed up automatically, on every device you write on. How your work is saved.

Losing track of a long book

Eye colours change, the dead come back, a promise from chapter three is never paid off.

The hardest part isn't creating ideas, it's remembering all the little details months later when you're 50k words in.

A writer on r/fantasywriters, July 2026

I find my head works fine up to about 30K words but somewhere past that things start slipping.

A writer on r/writing, March 2026

What Onwarder does

The story bible is a click from the page, story events record who knew what and when, and the continuity check warns when a dead character walks back in. No AI needed.

Tools that take a weekend to learn

Hours of setup, templates and settings before a single word of the novel.

I always end up getting stuck right at the learning curve, which usually puts me off.

A writer on r/fantasywriters, July 2026

I just wrote my last book in Scrivener. Although it's preferred by a lot of writers, it's too much for me.

A writer on r/writing, May 2026

What Onwarder does

Open Onwarder and type. No account, no setup and no course first; the story bible fills in as you need it.

Subscriptions and lock-in

Another monthly fee, a format only one app can open, and the fear the app shuts down.

Even with a one-time purchase, I rather not spend money on something that might terminate or might not work after purchase.

A writer on r/writers, June 2026

Would it also be not too harsh to ask if it can be not too expensive on the subscription fees or a permanent one?

A writer on r/writing, January 2026

What Onwarder does

Writing is free for good. Every book exports whole, at any time, on any plan: Word, EPUB, Markdown, PDF, or one file of your whole library.

AI pushed in, and trained on your book

Writing tools adding AI nobody asked for, and nobody sure where the manuscript goes.

If I just use a simple google doc, could that be used to train ai?

A writer on r/writers, August 2026

Does anyone have any software they recommend that AI won't be sifting through?

A writer on r/WritingHub, August 2026

What Onwarder does

AI is off for every book unless you turn it on, and Onwarder never uses your writing to train AI.

Formatting and export pain

The book is done, and then a week of fighting Word, compile settings and the KDP previewer.

Used to use Scrivener, but it's lack of portability and the struggle of exporting made me sadly abandon it. Now I use Word.

A writer on r/writing, May 2026

A bit annoying that I have to scrap all of that and do a PDF completely differently.

A writer on r/selfpublish, September 2026

What Onwarder does

When the last scene is done, Onwarder makes the EPUB and a paperback interior PDF at 5 by 8, 5.5 by 8.5 or 6 by 9 inches. Check each file in the store's previewer before you publish.

Read all 43 excerpts, grouped by problem, with their threads

What makes a writing tool worth it.

The book you end up with, and how sure you can be that you will get there, against how long it takes and what it costs you. Here is Onwarder on all four.

The book you wantA whole novel, consistent and finishedProof it worksSee every part before you trust it

Time to startSeconds, with no accountWhat it costs youNothing, and nothing locked in

A worn leather book on a dark surface, lit from above by a floating gold quest marker.

The book you want

A whole novel, finished, and in readers' hands.

Consistent from the first chapter to the last, and ready for the stores. Finishing turns the manuscript into the files a store, a printer and a narrator ask for. You check each file and publish it under your own name; Onwarder never publishes for you and takes no rights. With no account, it makes EPUB, Word, Markdown and PDF files, including paperback interiors. Private readers and the book page are part of Cloud.

The story bible. Characters, places, items and factions, opened over the page and back again.
The corkboard. The shape of the book as cards; drag a scene to move it.
Check and export. Word, EPUB or PDF, from the saved draft, checked first.

Everything a long novel needs. All of it free.

Your manuscript in the middle, and every character, place and promise behind it one click away. None of it needs AI, and none of it needs an account.

Level up, and the book remembers.

For LitRPG and progression writers. Give a character System details and change them as the story does. A new level, experience, a skill or ability, a title or a quest is recorded as an event; log it against a scene, and it appears in that chapter's System changes.

The last of the Ashfall guard went down on one knee and stayed there. Kaelen kept his shield up until the man's sword hit the flagstones.

The System spoke in the quiet after, the way it always did, as if it had been waiting politely for the noise to stop.

Something settled behind his ribs, heavier than a breath. The shield felt lighter. The yard felt smaller.

He tried the stance he had watched the old sergeant use a hundred times, and this time his body knew it.

Your Cloud books, with their history and files, stay readable and downloadable for 90 days after Cloud ends. We email you before that period ends, then those Cloud books are deleted. Each device keeps its own copy of your writing. Deleting the Cloud books does not affect writing on a device. Renew while your Cloud books are still there and they are kept. After deletion, renew and deliberately sync again to put writing from a device back in Cloud. Every book exports whole for as long as it is kept. Storage is counted in binary units: 1 GB is about 1 GB, and 10 GB about 10 GB.

Onwarder is free, and stays free: Writing in Onwarder with no account costs nothing and has no time limit, in your browser and in every Onwarder app. Only Onwarder Cloud is paid. That does not change.
Your words are yours: We claim no right to screen, train on or remove what you write. The only writing we delete is what you delete, and your Cloud copy at least 90 days after Cloud ends, after telling you. We never touch the books on your devices.
Export is always open: Every book exports whole, at any time, on any plan, trial spent or not. When Cloud ends, every book stays on your devices, so it exports for as long as you keep it.
The Cloud trial counts days you use: 30 days you actually write on, not 30 days on the calendar. Time away costs you nothing.

Your own AI: off unless you turn it on.

Onwarder works fully without AI. If you already pay for Claude, ChatGPT or Codex, connect it to your book, and it can explain your own story back to you while you draft. What else it may do is your choice, book by book. Onwarder never uses your writing to train AI.

It reads and suggests. It cannot change a word. Onwarder's server refuses every change a connected AI asks for, so this does not rely on the AI behaving well. Your manuscript and story notes change only when you change them.

Off until you allow it. AI access starts off for every book. Allow it for one book in that book's settings, and turn it off again whenever you like.

Ready-made roles. Ask your AI to work as a developmental editor, line editor, continuity checker, beta reader, LitRPG system balancer or voice check, or write your own role for a book. Each one works within what that book allows.

No AI credits. We don't sell AI or charge for it. Connect the plan you already pay for; your provider's terms apply. We never train AI on your book, and Onwarder's servers never call an AI model.

Questions writers ask before they start.

Is Onwarder free?

Yes. Writing in Onwarder is free on every device, with no account and no time limit: in any browser today, on a computer or a phone, and in Onwarder for Mac, Windows, Linux and iPhone. Onwarder Cloud is the paid part, at $10 a month or $99 a year, free for your first 30 writing days. Free and Cloud, line by line.

So how does Onwarder make money?

From Cloud. Writing stays free; writers who want their library on every device, backed up as they write, shared with readers or connected to their own AI pay for Cloud. We do not sell your data, sell AI credits or show adverts.

Will I lose my work?

Onwarder saves as you type, on your device, and you can save your whole library to one file whenever you like. With Cloud, every change is backed up as you write, with versions you can go back to. If two devices change the same words, Onwarder asks which to keep. Nothing is lost. If Cloud ends, sync pauses. Your Cloud books stay readable and downloadable for 90 days, with their history and files, then they are deleted. We email you before that period ends. Each device keeps its own copy of your writing, which Cloud deletion does not affect. After deletion, renew and deliberately sync again to put writing from a device back in Cloud. How your work is saved.

Can I bring the book I am already writing?

Yes. Import your Word manuscript in one step; Onwarder keeps chapters, headings, bold and italics and shows you what it found before anything is saved. Start with a copy, and keep your original until you are happy.

Can I get my book out again?

Always. Every book exports whole, at any time, on any plan, trial spent or not: Word, EPUB, Markdown, PDF, or one file of your whole library. That promise is written into the terms.

Do I have to write with AI?

No. Writing, story planning and learning do not require an AI account. Use assistance for the tasks you choose, or write every word yourself. Neither choice makes you more or less of an author.

Do you train on my book?

No. Onwarder does not use your manuscript to train AI models. If you connect your own AI, what it reads goes to that provider under its terms and data settings, so check them. Saving to your Onwarder account and allowing AI access are separate choices. Our privacy policy explains how we handle your data.

I already use Scrivener, Word or Google Docs. Why change?

You do not have to change everything. Bring one chapter, try the story bible and the continuity check, and export it back if you prefer. Where another tool is better, our comparison pages say so. Every comparison.

Is there a desktop app?

Onwarder for Mac: Available. Onwarder for Windows: Available. Onwarder for Linux: Available. Books you keep on your own computer are free and need no account. With Cloud, your whole library is there too, even offline. Download.

What works today, and what is still coming?

Onwarder for Mac: Available. Onwarder for Windows: Available. Onwarder for Linux: Available. Onwarder for iPhone: Beta. Onwarder for Android: Coming soon. Onwarder in your browser: Available. Move a book between devices with an .onwarder file. Today: automatic backup to Cloud; and sync between your devices.
