How to use the free AI book writer.

Describe the book in two or three sentences. Who it is about, what they want, and what stands in the way. For a memoir, write what happened and what it meant to you.
Choose a genre. It shapes the plan: a thriller gets a clock, a romance an obstacle between two people, a memoir chapters built only from what you described.
Choose 12, 20 or 30 chapters, then press Outline my book. The plan arrives in under a minute: a title, a logline, the main characters, the setting and one line per chapter.
Read it for the shape, not the words. Look for a strong opening, a turn in the middle, a crisis and an ending that answers the opening.
Keep what works and rewrite the rest. Run it again for a different plan, or copy it into your own document and make the chapter lines yours.

12, 20 or 30 chapters?

Outline	Suits	At about 4,000 words a chapter
12 chapters	A novella, a short memoir, a middle grade novel	About 48,000 words
20 chapters	Most adult novels and memoirs	About 80,000 words
30 chapters	A long novel, or a thriller with short, fast chapters	About 120,000 words, or less with shorter chapters

Fiction, memoir and children's books.

Fiction

Choose the genre. For a novel with point of view and subplots, use the free AI novel writer.

Memoir

Choose Memoir. The plan uses only the events you describe and names what each chapter should cover where details are missing.

Children's books

Choose Middle grade or Picture book. Keep the idea simple and the plan short, and read it aloud as you revise.

From outline to finished draft, in four steps.

Each step works on its own. Plan by hand and write every word yourself, or let Feldar draft and keep only what you like.

1. Outline the book

Keep the premise, the turns and the cast as cards on the Canvas, linked by relations such as Causes or Opposes.

2. Plan each chapter as scenes

Each page has an Outline. Type the scenes, or describe the beats and Generate scenes proposes some to edit, reorder or delete.

3. Draft the pages

Draft Page writes a page from its scenes at the length you set, up to ten pages in one run. New AI writing is marked in blue.

4. Revise

Polish, Deepen or Enhance a passage, run Checks, or ask Lens for a reader's view. Each change waits for your OK.

Scenes first, then the page.

The plan sits beside the page it belongs to, so the draft follows the scenes you chose.

How scene planning works

The chapter, planned

The scenes the writer typed or kept. Draft Page sits in the Outline's footer.

The ledger was in the bottom drawer of the bureau, under a seed catalogue from 1958 and a tin of the mints her father had sucked for his chest. It fell open, as she had known it would, at the last page he had used.

He looked at the page for a long time without touching it. Then he wiped his hands on the sack tied round his waist, slowly.

Then the page

Your words stay black. New AI writing is blue until you accept it.

A worked example: one book, from idea to a drafted chapter.

The Weighing House is an invented novel set in 1911, in a fen market town. Here is how its writer might use Feldar, and who did what.

Step	What the writer did	What Feldar did	What stayed
Premise	Wrote one line: a weighmaster's daughter finds her father's weights have cheated the town for twenty years.	Nothing. Writing and planning by hand never use credits.	The writer's line.
Story world	Made cards for Nell, her father and the Weighing House, and asked Chat to add a character two years older than Nell.	Chat proposed a card for Kit, who sets eel traps on the fen.	Kit's card, saved and linked to Nell.
Chapter plan	Typed the beats for chapter 7 and asked for scenes.	Generate scenes proposed scene titles and descriptions.	Most scenes, after the writer rewrote two and added the last by hand.
Draft	Set the page length and pressed Draft Page.	Wrote a first pass of the page from the scenes, marked in blue.	The opening and the ledger scene, which the writer then rewrote in her own words.
Revision	Selected a flat paragraph and chose Deepen, then ran Checks on the page.	Returned a rewrite with the new words marked, and a list of issues with fixes.	One rewrite and three fixes. The rest were discarded.
Record	Opened the Writing record.	Showed which words were typed and which came through Feldar's tools.	A private account the writer can use to answer a publisher's questions.

Questions about writing a book with AI

Is the book outline tool free?

Yes. You can make 10 outlines a day with no account and no card, and nothing you type is stored. It runs on Kimi K2.6, an open model by Moonshot AI, on Cloudflare Workers AI. The outline is a starting point: keep the chapters that work and change the rest.

Can Feldar write a whole book for me?

No. Draft Page can write a first pass of a page from the scenes you planned, but Feldar is not built to write books on its own. Each tool waits for your decision, and new AI writing is marked in blue so you can review it.

Who owns a book I write with Feldar?

You do. What you write in Feldar is yours, and Feldar does not use it to train AI models. Publishers and contests have their own rules on AI use, and the Writing record helps you answer them accurately.

Can I bring in an outline or a draft I already have?

Yes. Import a Word (.docx), PDF, Markdown or plain text file of up to 20 MB, then plan the next chapters as scenes.

Which AI models does it use?

You choose: GPT-6 Astra, Sol and Luna, and Claude Opus, Sonnet and Haiku 5.5, depending on your plan. The free Starter plan uses GPT-6 Luna.

Will the draft sound like me?

It gets closer if you give Voice & Style a sample of your prose and keep the cast and places on the Canvas. The sentences that matter most are still best written or rewritten by you.

How much does it cost?

The Starter plan is free with 500 credits and no card. Core is $20 a month with 20,000 credits.
