Honest comparison
Sudowrite pricing — and the half of the job it doesn't do
Sudowrite is one of the best-known AI fiction-writing tools: brainstorming, expanding outlines into prose, rewriting, and feedback, metered by monthly credits. Its pricing page advertises three tiers at $10, $22, and $44 per month (a monthly/yearly billing toggle offers up to 50% off for yearly, so confirm the billing period on their site). What no drafting tool does is the publishing: once the novel is finished, publish.ai turns the manuscript into a validated EPUB, print-ready PDFs, covers, and an Amazon listing — for a one-time fee.
| Sudowrite | publish.ai | |
|---|---|---|
| Pricing model | Subscription: Hobby & Student $10/mo (225,000 credits), Professional $22/mo (450,000–1,000,000 credits depending on billing), Max $44/mo (2,000,000 credits, 12-month rollover) — as advertised September 2026; yearly billing is discounted | One-time per book: $29.99–$99. No subscription, no credits, nothing to cancel |
| What it's for | Writing fiction with AI: brainstorming, outline-to-draft expansion, busting writer's block, rewriting, beta-style feedback | Publishing finished books: validated EPUB, print-ready PDFs, six designed covers, Amazon listing copy, launch graphics |
| Output | A manuscript (and a more fun time writing it) | A complete Amazon KDP launch package built from your manuscript |
| Metering | AI credits per month; heavier use of stronger models burns more credits | Flat price includes everything in the package — no meter |
| Free to try? | Free trial, no credit card required | Inspect a complete real sample package before paying anything |
| Your rights | They claim no rights over what you write or generate | Yours entirely — no royalty share, flat one-time payment |
Where Sudowrite is the better choice
An honest comparison cuts both ways. Sudowrite genuinely wins if:
You're still writing the novel
Sudowrite is a drafting partner, and a mature one — purpose-built fiction features and in-house models trained for narrative. If the manuscript doesn't exist yet, a launch package is premature; write the book first. publish.ai only enters the picture once the words exist.
You want ongoing feedback while you draft
Getting beta-style feedback chapter by chapter, alternates for a word that isn't landing, help through a blocked scene — that's a subscription-shaped need, and Sudowrite's whole design. A one-time publishing package can't help you mid-draft.

Common questions
How much does Sudowrite cost?＋
As of September 2026, Sudowrite's pricing page advertises three plans: Hobby & Student at $10/month with 225,000 credits, Professional at $22/month with 450,000–1,000,000 credits (the page shows both figures, likely varying with billing period), and Max at $44/month with 2,000,000 credits that roll over for 12 months. The page has a monthly/yearly billing toggle advertising up to 50% off for yearly, so check which billing period the displayed price reflects before subscribing.
Is there a free version of Sudowrite?＋
There's a free trial with no credit card required, but no permanently free plan is advertised. If you just want to see whether AI-assisted drafting suits you, the trial is the way to find out.
What happens when the draft is done?＋
Publishing — the half no writing tool covers. Amazon wants a validated EPUB, a print-ready interior PDF, a cover wrap with exact spine math, listing copy, keywords, and categories. publish.ai builds that whole package from your .docx in minutes, from $29.99 one-time, with every EPUB run through epubcheck.
I wrote my novel with Sudowrite — can publish.ai publish it?＋
Yes. Sudowrite claims no rights over what you write or generate with it, so the manuscript is yours to publish. Upload the .docx and the launch package comes back with a typeset interior, six genre-matched covers, print files, and Amazon listing copy.
Do I need both?＋
They don't overlap, so it's not either/or: Sudowrite (or any writing tool) gets the manuscript written; publish.ai gets it launched. Plenty of authors pay for a drafting subscription while they write, then a one-time package when the book is ready — that's cheaper than keeping a subscription running for features they no longer need.
Whatever you format with, our free tools work for every book: the KDP cover calculator, KDP royalty calculator, KDP manuscript checker, and more tools & guides.
