AutoCrit vs Sudowrite (2026): Editing Reports or AI Drafts?

AutoCrit and Sudowrite answer different questions. AutoCrit asks "how does the prose I wrote compare with published books in my genre?" and answers with editing reports and a score. Sudowrite asks "what could come next?" and answers by drafting, rewriting and expanding fiction with AI.

So pick by the job in front of you. If you have a draft and want to polish it, AutoCrit is the closer fit. If you want help producing scenes, Sudowrite is. As listed on 23 October 2026, AutoCrit Pro costs $15 a month billed annually, and Sudowrite runs from $10 to $44 a month billed yearly.

StoryWith AI is our own product, so weigh what we say about it accordingly.

Key takeaways

• AutoCrit is a self-editing platform: "25+ interactive editing tools plus advanced reports," a Summary Report with an AutoCrit Score, and comparison with genres. Its FAQ says the editing reports use "no generative AI."
• Sudowrite is an AI writing partner: Write, Rewrite, Describe, Expand, Brainstorm, Story Bible and Chat, on its own fiction models plus "+30 industry-leading models."
• Pricing models differ. AutoCrit Pro is a flat $30 a month or $15 a month billed annually. Sudowrite sells monthly credits; only the Max plan rolls unused credits over.
• Feedback on your draft: AutoCrit's reports are on every Pro plan. Sudowrite's Feedback (developmental, line, dialogue and copy edits, plus an AI beta read) is on Professional and Max only.
• Neither drafts and edits equally well. AutoCrit's Inspiration Studio "will not generate prose for you." Sudowrite has no score or genre benchmark.
• Both say your writing is not used to train their AI; Sudowrite's statement names its own and OpenAI's models.

What is the difference between AutoCrit and Sudowrite?

Features as listed on AutoCrit's pricing page, FAQ and help centre, and Sudowrite's pricing page and help centre, read on 23 October 2026.

What does AutoCrit do?

AutoCrit is a browser-based editor with reports in a side panel. Its pricing page lists "25+ interactive editing tools plus advanced reports including Pacing, Dialogue, and Strong Writing," a "Summary Report with AutoCrit Score and Editing Recommendations," and the option to "Compare your style with major select genres."

Its FAQ is direct about how the reports work: "All editing reports are algorithmic and based on comparative data sets, with no generative AI involved." The same answer says generative AI is used in the Inspiration Studio, which its own page describes as producing ideas and suggestions. Asked whether the studio writes prose, that page answers: "No. The Inspiration Studio will not generate prose for you."

Pro also adds Story Analyzer+, automated alpha and beta readers, Market Fuel for marketing copy, and ePub and PDF formatting. AutoCrit's help centre calls Story Analyzer+ and the virtual readers "AI analysis features," but does not say which model powers them.

On the score, AutoCrit's help centre (18 September 2026) is careful: "AutoCrit's Overall Score is not a judgment of the quality of your writing." By default it compares you with General Fiction.

What does Sudowrite do?

Sudowrite is built to produce text with you. Its help centre describes Write as "like the most advanced autocomplete ever," reading up to 20,000 words of what came before and writing 50 to 2,000 words. Rewrite works on up to 6,000 words at once, and Expand builds out a passage of up to 1,000 words at a time. Story Bible "gathers the core elements of your story in one place" so the AI can reference them.

For revision, Sudowrite has Feedback. Its help article (updated 13 May 2026) says Feedback "reads your work and leaves comments in the margin, just like a real editor," that its types include Developmental, Line, Dialogue and Copy Edits, and that it "is exclusive to Professional and Max plans." It also offers a Beta Read from three AI readers.

What Sudowrite does not offer is AutoCrit's kind of counted report. We found no Sudowrite help article describing a score, adverb counts or a comparison with published books in your genre.

How much do AutoCrit and Sudowrite cost?

AutoCrit has a free plan and one paid plan, Pro: $30 a month, or $15 a month billed annually, as listed on AutoCrit's pricing page on 23 October 2026. The free plan has no word limit but only the Adverbs, Word Choice and Readability tools. Our AutoCrit review has the full plan table and its refund terms.

Sudowrite has three plans. Billed yearly, Hobby & Student is $10 a month, Professional $22 and Max $44, as listed on Sudowrite's pricing page on 23 October 2026. Feedback, its revision tool, is on Professional and Max only. Our Sudowrite vs ProWritingAid comparison has the monthly prices, the credits on each plan and how rollover works.

Sudowrite plans are metered in credits, and credits do not map neatly to words. Sudowrite's help centre (7 January 2026) says the same 200-word Write cost about 70 credits on one model and over 8,000 on another. AutoCrit charges nothing per report.

A year on each

A hypothetical comparison at yearly prices: AutoCrit Pro is $180 a year ($15 x 12), with no per-run charge for any report. Sudowrite Hobby & Student is $120 a year but has no Feedback; Professional, the cheapest plan with Feedback, is $264; Max is $528.

Which is better for revising a finished draft?

AutoCrit, for sentence-level polish. You get repeatable reports, a score you can watch move, and a genre benchmark, and a flat price means a rerun after each pass costs nothing extra. The reports flag; you decide what to change.

Sudowrite's Feedback can also comment on a draft, from structure down to copy edits, and its Rewrite will offer new wording. That wording is generated, so if you want every sentence of the final book to be yours, treat Rewrite output as suggestions to rework rather than text to paste.

Independent reviewers have mixed views on AutoCrit's depth. Dave Chesson at Kindlepreneur, in a roundup of writing software (updated 21 September 2026), wrote that AutoCrit's feedback "never feels very deep" and that "compared to newer AI tools, it just feels a bit behind." Chesson co-founded the competing Atticus, which that article ranks first, so weigh it accordingly.

Which is better for drafting?

Sudowrite. Drafting is what it is for. In the same Kindlepreneur roundup, Chesson called Sudowrite "one of the few AI tools I've actually found useful for fiction," and added: "I'd never use Sudowrite to write a book for me." Jamie Biggs at The Write Practice (29 October 2025) wrote that "Sudowrite is not a replacement for creativity. It is a tool that helps you keep the momentum going when the words are slow to come."

AutoCrit's Inspiration Studio offers mood suggestions, "What Happens Next?" plot ideas and a contextual thesaurus, but it will not draft scenes.

If you plan to publish on Amazon, check KDP's rules before you draft with AI. KDP's content guidelines, read on 23 October 2026, say text an AI tool created counts as "AI-generated," "even if you applied substantial edits afterwards," and must be disclosed. Text you wrote and then edited with AI tools is "AI-assisted" and does not need disclosing. Our guide to AI-assisted vs AI-generated writing goes through the difference.

Where StoryWith AI fits

StoryWith AI is closer to AutoCrit's side of the line: it reads the manuscript you wrote rather than writing it, and text changes only when you ask for an edit and accept it. It works mainly at the story level rather than the sentence. It returns ranked diagnostics: one list of what to fix, sorted by severity, with each finding linked to the passage that caused it. So where AutoCrit would flag the adverbs in a chapter, StoryWith AI asks whether the chapter earns its place, whether a character's arc holds across the book and whether an early promise gets paid off. Our features page lists every analyzer.

The free plan's one-time allowance covers a first book-level pass, so you can see the kind of findings before paying. Our pricing page lists what each paid plan adds, including reader sessions with real people you invite.

It is the wrong tool if you want AI to draft scenes, which is Sudowrite's job. It is also the wrong tool if you want counted line reports and a genre score, which is AutoCrit's.

Frequently Asked Questions (FAQ)

Is AutoCrit or Sudowrite better?

They do different jobs. AutoCrit is better for measuring and polishing prose you wrote, with editing reports, a score and genre comparison. Sudowrite is better for generating, rewriting and expanding fiction with AI. If you use both, use them at different stages: Sudowrite while drafting, AutoCrit while revising.

Does AutoCrit use AI like Sudowrite?

Not in the same way. AutoCrit's FAQ says its editing reports are algorithmic, with no generative AI, and that generative AI is used in the Inspiration Studio for ideas and suggestions. That studio "will not generate prose for you." Its help centre also lists Story Analyzer+ and the virtual readers as AI analysis features, which comment on your manuscript rather than write it. Sudowrite's main tools generate prose.

Can Sudowrite edit my novel like AutoCrit?

Partly. Sudowrite's Feedback, on the Professional and Max plans, leaves developmental, line, dialogue and copy-edit comments in the margin. It does not give you a score, counted reports such as adverb frequency, or a comparison with published books in your genre, as far as its help centre shows.

How much do AutoCrit and Sudowrite cost?

As listed on 23 October 2026, AutoCrit Free is $0 and Pro is $30 a month or $15 a month billed annually. Sudowrite is $10, $22 or $44 a month billed yearly, or $19, $29 or $59 billed monthly, depending on the plan.

Do AutoCrit or Sudowrite train AI on my writing?

Both say no. AutoCrit's FAQ answers "Absolutely not" when asked whether your writing trains its AI, and Sudowrite's pricing FAQ says "we do not use your writing to train Sudowrite or OpenAI's AI models."

Does AutoCrit have a free plan, and does Sudowrite?

AutoCrit has a Free plan with no word limit and a few tools, including Adverbs, Word Choice and Readability. Sudowrite offers a free trial with no credit card, and its help centre says paid plans can be refunded if you ask in the first week.

Do I have to disclose Sudowrite or AutoCrit use on Amazon KDP?

It depends on what the tool did. KDP requires you to disclose AI-generated text, meaning text an AI tool created, even if you edited it heavily. Text you wrote and then checked or refined with AI tools is AI-assisted, which KDP does not require you to disclose. Check KDP's current guidelines before you publish.
