What Is the Difference Between the Free Marlowe Report and Marlowe Pro?

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.
