authors.ai

Authors A.I. is an analytical AI editing service for novelists, built around a tool called Marlowe. Instead of generating or rewriting prose, it reads your manuscript and returns developmental feedback on plot, pacing, characters, and story structure — typically in about 10 minutes. It suits fiction authors at any stage: those with rough drafts, completed manuscripts, or a full backlist. The free report covers readability, cliché use, and writing stats; deeper analysis of story beats, character arcs, theme, and subplots sits behind Marlowe Pro at $19.95/mo.

How Marlowe differs from generative AI writing tools

Most AI writing tools are built to produce text. Authors A.I. is explicitly the opposite: the site states Marlowe "never generates or rewrites text." It analyzes what you've written and hands the creative decisions back to you.

That distinction matters if you're using AI to improve a manuscript rather than draft one. A generative tool might suggest a new scene; Marlowe tells you where your pacing drags or a character arc flattens, and you decide what to do about it. The service was designed by bestselling authors and data scientists, with cross-genre attention to structure and character arcs.

What you get

Both tiers run through the Author Dashboard, where the critique appears after upload.

How it works

1. Upload a manuscript. Marlowe accepts rough drafts, completed works, or an entire backlist of titles.
2. Wait for analysis. Results appear in your Author Dashboard in roughly 10 minutes, with the site advertising under 15 minutes for the full process.
3. Read the developmental feedback. You get observations on plot, characters, story beats, and pacing — not rewritten text.
4. Revise on your own terms. Every creative decision stays with you.

For genre comparison, you'll need Marlowe Pro.

Privacy and data handling

The site makes three specific commitments: no AI models are trained on your uploads, no human sees your manuscript, and you can delete all your data at any time. It describes use of its editing tools as 100% confidential. If you're protective of unpublished work, these are the claims to verify against the current privacy policy before uploading.

Who it's for

• New authors who want a structural read on a first draft before querying or self-publishing.
• Published authors who want a fast developmental pass between drafts.
• Prolific authors with multiple titles who want consistent analysis across a backlist.

The site cites 40,000+ authors using the service, with testimonials from romance, thriller, and USA Today bestselling authors. One reviewer describes it as "an indispensable first pass for your novel" — a framing worth taking literally: it's a first pass, not a final edit.

What to check before signing up

• Pricing details. The $19.95/mo. figure comes from the site's own description of Marlowe Pro; confirm current plans on the pricing page, since tiers and terms can change.
• Genre fit. The tool is built for fiction novels. If you write nonfiction, the plot-and-character framing may not map to your work.
• What "free" covers. The free report is real but limited to readability, clichés, and writing stats. Story beats, arcs, theme, and comps require Pro.

If you want an analytical second read on a novel — and you're comfortable making every revision decision yourself — Marlowe is built for exactly that job.

The free Marlowe report gives you baseline writing metrics — readability score, cliché usage, and writing stats — while Marlowe Pro ($19.95/mo.) adds developmental analysis of story beats, character arcs, theme, and subplots, plus comparisons to bestselling authors in your genre. Choose the free report if you only need a quick diagnostic on prose-level issues; upgrade to Pro if you're revising structure, character development, or market positioning and need feedback at the story level.

What the free Marlowe report covers

According to Authors A.I., the free report is available through your Author Dashboard and includes:

• Readability score — how easily your prose reads
• Use of clichés — flagging overused phrases and constructions
• Writing stats — quantitative measures of your manuscript

The free tier also includes the core analysis itself: Marlowe reads and analyzes your draft to provide developmental feedback, and the site states it never generates or rewrites text. The full analysis is delivered in about 10 minutes, and the service handles rough drafts, completed works, or an entire backlist.

One important limit: the free report is a diagnostic, not a structural edit. It tells you how your writing measures up at the sentence and surface level, but it does not break down how your plot, characters, or pacing compare to what sells.

What Marlowe Pro adds

Marlowe Pro is priced at $19.95/month and layers advanced analysis on top of the free report:

The comparison feature is the most consequential addition. Pro lets you benchmark your manuscript against top bestselling authors in your genre — what the site calls "discovering your comps." That's a market-positioning tool as much as a craft tool: it tells you whether your structure, pacing, and character work land in the same territory as books that already sell in your category.

How to decide

The decision comes down to what stage of revision you're in and what kind of feedback you can act on.

Stay on the free report if:

• You're early in a draft and mainly want to catch prose-level problems (readability, clichés, stats)
• You want to test whether Marlowe's feedback style is useful to you before paying
• You already have structural feedback from beta readers, an editor, or a critique group

Upgrade to Pro if:

• You're revising at the story level — plot, pacing, character arcs, theme, subplots
• You want to know how your book compares to bestselling comps in your genre before querying or self-publishing
• You're working through a backlist and want consistent developmental analysis across multiple titles

A practical approach: run the free report first. If the prose-level feedback is useful and you find yourself wanting to know why the story isn't landing — not just whether the sentences are clean — that's the signal that Pro's structural analysis is worth the $19.95/month. If the free report already tells you what you needed, there's no reason to pay for dimensions you won't act on.

Privacy and access notes

Authors A.I. states that no AI models are trained on your uploads, no human sees your manuscript, you can delete all your data at any time, and your use of the tools is 100% confidential. The service is described as trusted by 40,000+ authors. Pricing and plan details are listed on the site's pricing page; check there for current terms before subscribing, since the $19.95/month figure reflects the information available at the time of writing.

Authors A.I. analyzes fiction manuscripts at almost any stage of completion — rough drafts, finished novels, and even a full backlist of titles. The service is built specifically for novels, so genre fiction and literary fiction are the target, and the feedback covers plot, pacing, story beats, and character arcs rather than line-level copyediting.

Manuscript types and stages it handles

According to the site, Marlowe (the analysis engine) "handles rough drafts, completed works — or your entire backlist of titles." That means you don't need a polished manuscript to get useful feedback.

What it is designed to analyze

Marlowe was "designed by bestselling authors and data scientists for deep analysis of fiction novels." The feedback is developmental, not generative — the site states it "never generates or rewrites text." You stay responsible for every creative decision.

The free report includes readability score, use of clichés, and writing stats. Marlowe Pro ($19.95/mo.) adds advanced analysis of story beats, character arcs, theme, and subplots, plus comparison to top bestselling authors in your genre.

Who it fits

The service is positioned for authors at all levels. Testimonials on the site come from romance, thriller, and other genre authors, including debut writers and USA Today bestselling authors. One quoted author calls it "perfect for an author just starting out," while another describes it as "an indispensable first pass for your novel."

If you write nonfiction, the site gives no indication that Marlowe is built for it — the described analysis (plot, character arcs, story beats, comps to bestselling novelists) is fiction-specific.

Practical notes before uploading

• Turnaround: results appear in your Author Dashboard in about 10 minutes; the site elsewhere describes the process as under 15 minutes.
• Privacy: no AI models are trained on your uploads, no human sees your manuscript, and you can delete your data at any time.
• Access: you can get started for free, and the free report is available without the Pro subscription. Current pricing details are on the site's pricing page.

If your goal is developmental feedback on a novel — finished or not — Authors A.I. is built for that task. If you need copyediting, proofreading, or nonfiction analysis, look elsewhere.

Yes, according to Authors A.I.'s own published statements. The site states that no AI models are trained on your uploads, no human sees your manuscript, you can delete all your data at any time, and your use of the AI editing tools is "100% confidential." Those four commitments are the core of the safety case, and they cover the two risks authors usually worry about most: having their text absorbed into a model, and having a person read their unpublished work.

What Authors A.I. Says About Privacy

The privacy claims come directly from the site's own description of the service. In its words:

• No training on your uploads. Your manuscript is not used to train AI models.
• No human review. No person sees your manuscript.
• Deletion on demand. You can delete all your data at any time.
• Confidential use. The site describes use of its AI editing tools as 100% confidential.

These are vendor statements, not independently verified audits. That distinction matters: they tell you what the company commits to, not what a third party has confirmed. If your situation requires contractual or legal guarantees, treat the site's wording as a starting point for a direct question to the company rather than as a finished answer.

Why the "Analytical, Not Generative" Design Matters Here

Authors A.I. is explicit that its tool, Marlowe, "never generates or rewrites text." It reads and analyzes your draft to produce developmental feedback — plot, pacing, characters, story beats, structure, character arcs, and (on the paid tier) theme and subplots.

This is relevant to privacy in a practical way. A tool whose job is to critique your existing text has no reason to reproduce or repurpose that text, and the company's stated model is analysis rather than generation. That doesn't by itself guarantee anything, but it aligns with the no-training claim: the product's purpose is to describe your manuscript back to you, not to produce new writing from it.

What You Upload and What Comes Back

Understanding the flow helps you judge the risk for your own project.

1. You upload a manuscript. The site says Marlowe handles rough drafts, completed works, or an entire backlist of titles.
2. Marlowe analyzes it. Results appear in your Author Dashboard in roughly 10 minutes, with the site elsewhere citing "less than 15 minutes."
3. You get developmental feedback. The free report includes readability score, use of clichés, and writing stats. Marlowe Pro ($19.95/mo., per the site) adds analysis of story beats, character arcs, theme, subplots, and comparisons to bestselling authors in your genre.
4. You make every creative decision. The site frames the output as feedback to incorporate into your own rewrite.

The manuscript is the input; the output is a critique. Nothing in the described workflow involves publishing, sharing, or redistributing your text.

Questions the Site Doesn't Answer

The published material covers the headline privacy points but leaves some practical details unstated. Before uploading something you consider sensitive, it's reasonable to ask the company directly about:

• Retention windows. "Delete at any time" describes your control, but not whether data is retained by default until you act.
• Where data is stored and which subprocessors are involved. Not addressed on the page.
• What deletion actually removes. Whether it covers backups and logs, not just the active copy.
• Whether the no-training commitment is contractual. The site states it; whether it's backed by a formal agreement is a separate question.

None of these gaps contradict the site's claims — they're simply outside what the page states.

A Practical Way to Decide

If your concern is "will a person read my unpublished novel" or "will my prose end up in a model," the site's stated policies address both directly, and the analytical-not-generative design is consistent with them. For most authors weighing a critique tool, that's likely enough to try the free report.

If your manuscript is under a contract, subject to an NDA, or otherwise legally sensitive, the safer path is to confirm the specifics in writing with Authors A.I. before uploading — particularly retention, deletion scope, and whether the confidentiality commitment is contractual. The site gives you the claims to verify; it doesn't substitute for verifying them when the stakes are high.

Marlowe, the analytical AI behind Authors A.I., reads your uploaded manuscript and returns developmental feedback through your Author Dashboard in about 10 minutes. It does not generate or rewrite text — you make every creative decision. The free report covers readability, cliché use, and writing stats; Marlowe Pro ($19.95/mo.) adds story beats, character arcs, theme, subplots, and comps to bestselling authors in your genre.

What Marlowe is and isn't

Marlowe is an analytical AI editorial partner designed by bestselling authors and data scientists for fiction. It reviews your draft rather than writing it: no text is generated or rewritten, and the service positions itself as a first-pass critique you incorporate into your own revision.

Two practical implications follow from that design:

• You stay the author. Feedback is developmental input, not replacement prose.
• It works on fiction specifically. Cross-genre insights target structure, pacing, and character arcs rather than general prose correction.

How the analysis process works

The workflow has two steps.

1. Upload a manuscript. Marlowe accepts rough drafts, completed works, or an entire backlist of titles.
2. See the results. Your Author Dashboard shows the critique in about 10 minutes.

From there, you read the feedback and decide what to change in your rewrite. The service describes the turnaround as "less than 15 minutes" in one place and "about 10 minutes" in another — treat roughly 10–15 minutes as the expected window.

Privacy and data handling

Authors A.I. states that no AI models are trained on your uploads, no human sees your manuscript, you can delete all your data at any time, and use of the editing tools is confidential. If manuscript confidentiality is a deciding factor for you, these are the specific commitments the site makes.

What the free report includes

The free report is available through the Author Dashboard and covers:

• Readability score
• Use of clichés
• Writing stats

This is the tier to start with if you want to see how Marlowe reads your prose before paying anything.

What Marlowe Pro adds

Marlowe Pro ($19.95/mo.) extends the analysis to story-level elements:

The comps feature is the one most tied to the "bestseller" framing: Pro compares your work to top bestselling authors in your genre, which is useful if you're positioning a book for query letters or market fit.

How to decide which tier fits

• Choose the free report if you want a quick read on prose-level issues — readability, clichés, stats — before committing to a subscription.
• Choose Marlowe Pro if your questions are structural: whether your beats land, whether character arcs hold, whether subplots and theme come through, and how your book compares to genre bestsellers.

Because Pro is billed monthly at $19.95, a reasonable approach is to run the free report first, then subscribe for the period when you're actively revising structure rather than drafting.

What authors report

Testimonials on the site come from authors across genres and career stages:

• AD Justice (romance author) ran an unfinished manuscript and called the feedback "SOOO helpful."
• Jonathan Baldie (thriller author) said the Marlowe Pro tool is "so good you won't believe it until you try it."
• Ellis Leigh (USA Today bestselling author) called it "a powerful and impressive tool for authors of all levels."
• Avery Jenkins (published author) found the report contained "much more than I expected, with solid insights."
• Sarah Dalton (bestselling author) described it as "an indispensable first pass for your novel."
• Dee Cooper (published author) called it "one of my new favorite tools."

The recurring theme is first-pass developmental feedback — authors use it to catch structural and prose issues before investing in human editing.

Common questions before you upload

Does it rewrite my book? No. Marlowe never generates or rewrites text; it provides feedback for you to act on.

Can it handle an unfinished draft? Yes — at least one testimonial describes running an unfinished manuscript, and the upload step accepts rough drafts.

Can I use it on multiple books? The upload step is described as handling a single manuscript or an entire backlist of titles.

How long until I see results? About 10 minutes, per the "How it works" section.

Is my manuscript used for training? No, per the site's privacy statements, and you can delete your data at any time.
