Sudowrite or Extypis: which is better for writing a novel, with or without AI?

Sudowrite is writing software built around AI, which drafts scenes and chapters from your outline and is paid in credits; Extypis is a writing workshop where AI remains optional, with a free account, then a monthly subscription. Here is how each one answers the questions people ask before choosing, what its users say about it, and the rounds Sudowrite wins are on the board.

How this page was made

Every line about Sudowrite was read on 17 October 2026 on sudowrite.com, its pricing page and FAQ, its help center, its changelog and its App Store listing. Its prices are shown there in US dollars, and its pricing page gives two different credit counts for the Professional plan: we follow its help. User reviews come from Trustpilot, App Store reviews, its feedback board, a published review and the press, each with its link. Extypis prices and limits are read live from our pricing page. The AI credits of the two programs cannot be compared: they do not buy the same thing.

Sudowrite in figures

The rating gaps between the App Store and Trustpilot come down to who leaves a review: the App Store rating also counts ratings with no text.

What do I pay?

  • How much do I pay, and for how long?

    Better answer

    Extypis

    You pay nothing, with no time limit, with 1 project and at most 15,000 words per project

    Sudowrite

    Nothing during the trial, with no bank card; there is no free version

  • What can I do without a subscription?

    Better answer

    Extypis

    Write, organise and export, with no time limit, with 300 AI credits given once

    Sudowrite

    Open and export your projects; no AI tool works without a plan, and AI is the whole software

  • And if I write on a computer, a tablet and a phone?

    Extypis

    The free account opens in the browser of each device, and you find the same text everywhere

    Sudowrite

    In the browser, and in cut-down iPhone and Android apps: no series folders and no sheet generation

Who writes, and how do I organise my novel?

  • Does the software write in my place?

    Extypis

    Only if you ask: the AI rewrites, continues or comments on the passage you choose, and you keep or refuse each suggestion

    Sudowrite

    That is its purpose: it drafts a first version, scenes or whole chapters from your outline and your sheets

  • Can I write with no AI at all?

    Better answer

    Extypis

    Yes: one setting removes every AI tool from the screen; only importing a manuscript still goes through an AI

    Sudowrite

    By not clicking its buttons: no setting removes AI from the screen

  • While I write, do I see the pages of my book?

    Better answer

    Extypis

    Yes, on a computer: you write in the pages, at the size, margins and font of your PDF

    Sudowrite

    No: you write in a continuous text field, with no page size

  • Can I keep sheets for characters, places and objects?

    Extypis

    Yes: characters, places, objects, events and your own categories, with their fields, images and documents

    Sudowrite

    Yes: its Story Bible keeps character and world sheets, with a portrait, which the AI can fill in and reads in order to write

  • If I name a character, even by a nickname, does the app find them?

    Better answer

    Extypis

    Yes, everywhere in the book, as soon as the nickname is on their sheet; a tab suggests the names in the text that have no sheet yet

    Sudowrite

    No: you note nicknames by hand on the sheet, so that the AI understands them, but the text is not scanned

  • Can I see the relationships between my characters and the timeline of the story?

    Better answer

    Extypis

    Yes: a map shows the links you write between sheets, and a timeline places each event at its date in the story

    Sudowrite

    No: its help describes neither a relationship map nor a timeline of a book's events

  • Can I see my whole story scene by scene, and reorder it?

    Better answer

    Extypis

    Yes, up to 10 sheets per project: each scene is a card with its summary, and moving the card moves the text

    Sudowrite

    An outline of summarised chapters, reordered by dragging them, and a free-form canvas of cards; its help does not say that moving a chapter in the outline moves the text

And AI?

  • Which AI can I use?

    Extypis

    Tools to rewrite a passage, continue a scene, generate a sheet or review a chapter, with 300 credits given once
    Better answer

    Sudowrite

    During the trial, its writing tools, its Muse model trained for fiction, and about fifteen models to choose from, from Claude to GPT and Gemini

  • Are my texts used to train an AI?

    Extypis

    No: neither Extypis nor its AI providers reuse them, and they are sent under a “no training” condition

    Sudowrite

    No, according to its FAQ: neither Sudowrite nor OpenAI trains their models on your texts; its privacy policy does not address it

Which language can I write in?

  • Which languages is the interface in?

    Better answer

    Extypis

    In French, English, Spanish, German and Chinese

    Sudowrite

    In English; its help acknowledges that some tools answer in English even to a text written in another language

How do I get, print and share my book?

  • Do I get a PDF for the printer and an EPUB for the e-reader?

    Better answer

    Extypis

    Yes: Extypis typesets the PDF with LaTeX, in A4, A5 or Letter, and exports the EPUB, up to 2 exports per month

    Sudowrite

    No: it exports to Word, a .zip archive or a .csv table, with no PDF and no EPUB

  • Can I publish my book in the app, so people read it online and send comments?

    Extypis

    Yes: the book has its reading page, open to everyone, and readers with an account comment paragraph by paragraph

    Sudowrite

    Yes, by a link: each reader receives their own copy, where they comment on passages without seeing the others' comments

  • Can I show how much of my text I typed myself?

    Better answer

    Extypis

    Yes: the “human origin” certificate says what was typed, pasted, moved or written by Extypis's AI, and is shared by a link; it does not say where the ideas come from

    Sudowrite

    No: its documentation describes nothing that distinguishes typed text from text the AI drafted

  • Can I bring in a manuscript started elsewhere?

    Extypis

    Yes: Word, PDF, EPUB, Markdown or HTML, as long as the manuscript fits in 15,000 words, with the character sheets already filled in

    Sudowrite

    Yes: text, Word, RTF or OpenDocument up to about 120,000 words, with a pre-filled Story Bible, and Scrivener backups

What its users like about Sudowrite

A summary of what comes back in published reviews, each with its link. We paraphrase rather than quote.

What bothers its users, and how Extypis answers

The complaints that come back, from the most frequent to the rarest. Opposite each one, what Extypis does, including when it does no better.

  1. The complaint

    Credits are unpredictable and expire each month: a hungry model empties the month's allowance on a single import, a failed generation can still cost, and 10,000 trial credits are not enough to judge a novel.

    Reviews on Trustpilot · Sudowrite on the App Store · Sudowrite, feedback board

    Extypis's answer

    At Extypis, credits only serve the AI tools, which are optional: writing, organising, publishing and exporting use none.

  2. The complaint

    Billing and cancellation cause problems: charges after a cancellation, the annual plan billed instead of the monthly one, a management button in error, refunds refused.

    Reviews on Trustpilot · Reviews on Trustpilot, page 2 · Sudowrite on the App Store

    Extypis's answer

    The subscription is cancelled in one click from the dashboard, with no notice, and access runs to the end of the paid period.

  3. The complaint

    The AI strays from what you wrote: it ignores the Story Bible, changes names, motivations or facts, or repeats itself; one test saw a character's eye colour change around the fifteenth chapter.

    Sudowrite on the App Store · Reviews on Trustpilot · UC Strategies review, January 2026

    Extypis's answer

    Extypis AI proposes, and you keep or refuse each change: it replaces nothing without your action. It can be wrong too, and does not guarantee the book's consistency.

  4. The complaint

    The mobile app is cut down, and the iPad is sent to it: no sheet generation, no series folders, crashes and edits that do not apply.

    Sudowrite on the App Store · Help: the mobile app

    Extypis's answer

    The phone and the tablet open the same Extypis as the computer, in the browser; only writing in the pages of the book needs a computer.

  5. The complaint

    Outages: timeouts, requests blocked by another in progress, and Story Bible content gone for some, up to four hours of work.

    Sudowrite on the App Store · Reviews on Trustpilot

    Extypis's answer

    Your text and your sheets are saved continuously, with a local copy in case of a dropout, and a deletion waits 30 days in the trash.

  6. The complaint

    Filtering of adult scenes is uneven: authors have a scene refused, despite a model presented as unfiltered, and an uncensored mode is the most followed request.

    Sudowrite on the App Store · Sudowrite, feedback board

    Extypis's answer

    Extypis does not promise an unfiltered AI: its models may refuse some scenes. What you type yourself is never filtered.

  7. The complaint

    Some authors refuse AI writing tools: in May 2023, the launch of its novel engine raised questions of consent, training data and jobs, in the middle of the screenwriters' strike. Sudowrite replied that it had collected and trained nothing without consent.

    Gizmodo, May 2023 · Genre Grapevine, May 2023 · Reviews on Trustpilot, page 2

    Extypis's answer

    Extypis AI is optional, a mode removes it from the screen, and the “human origin” certificate shows what you typed yourself.

  8. The complaint

    English first: the interface remains in English, and one user who had prepared everything in French received a first draft in English.

    Sudowrite on the App Store (Canada) · Sudowrite, feedback board · Help: writing in other languages

    Extypis's answer

    The Extypis interface exists in French, English, Spanish, German and Chinese.

What Sudowrite does better

  • Its AI is specialised in fiction: an in-house model, Muse, and about fifteen models to choose from, from Claude to GPT and Gemini.
  • It drafts a first version or whole chapters from your outline and your Story Bible, which Extypis does not do.
  • Its Professional and Max plans give AI feedback on structure, style and the reading of a manuscript.
  • It has apps for iPhone and Android, and its entry plan costs $10 per month paid annually.
  • It reads a Story Bible shared by all the books of a series before writing.

What Extypis does that Sudowrite does not

  • It is for writing without AI, for free and with no time limit, and one setting removes AI from the screen.
  • You write in the pages of the book, at the size, margins and font of your PDF, and you export to PDF and EPUB.
  • It finds your characters in the text by name or nickname, draws the map of their relationships and places events on a timeline.
  • It issues a “human origin” certificate that distinguishes what you typed from what the AI wrote.
  • Its interface exists in five languages, and your book can have a public reading page where your readers comment.

Moving from Sudowrite to Extypis

Sudowrite exports a project as a single Word file, without the Story Bible. Import that file into Extypis: it is split into chapters and scenes, and the characters who come back often already have their sheet, filled with what the text says about them. Sudowrite's sheets are exported separately, as a .csv table, and copied over. The free account imports a manuscript as long as it fits in 15,000 words; beyond that, importing requires a subscription.

The questions people ask us

Is Sudowrite free?
No. It offers a trial with no bank card, of 10,000 credits according to its blog, then three plans: Hobby & Student ($10 per month annually, $19 monthly), Professional ($22 or $29) and Max ($44 or $59). Without a plan, you can open and export your projects, but no AI tool works (surveyed on 17 October 2026).
How do Sudowrite's credits work?
Each plan gives credits per month: 225,000, 1,000,000 or 2,000,000. A tool uses some depending on the model and the length of the text: its help cites about 70 credits for a 200-word continuation with GPT-5 Nano, and more than 8,000 with Claude 4.1 Opus. Credits expire each month, except on the Max plan.
Is Sudowrite available in French?
Its interface is in English. Its help says you can write in nearly every language, but that some tools answer in English. The Extypis interface exists in French, English, Spanish, German and Chinese.
What is the difference with Extypis?
Sudowrite is built around AI, which drafts scenes and chapters and is paid in credits. Extypis is a writing workshop: sheets, relationship map, timeline, scene board and writing in the pages of the book, free up to 15,000 words per project, with an optional AI in the 13 € per month plan.
Are my texts used to train Sudowrite's AI?
According to the FAQ on its pricing page, no: neither Sudowrite nor OpenAI trains their models on what you write, and Sudowrite claims no rights over your texts. Its privacy policy does not address the question. At Extypis, your texts are never used to train a model, neither by us nor by our AI providers.
How do I move from Sudowrite to Extypis?
Export your project as a single Word file from Sudowrite, then import it into Extypis: it is split into chapters, and the characters who come back often already have their sheet. The Story Bible sheets are exported separately as .csv. The free account imports a manuscript of at most 15,000 words.
