Galley vs. Novelium
Last reviewed July 2026
The facts first: Novelium (a subscription of $0–$19/month on its listed tiers, up to $147/month for the top add-on tier; runs in the browser) uses AI to read your manuscript and flag inconsistencies in the timeline, characters and plot. It also has a character dashboard, a world codex, and export to PDF, EPUB and DOCX with book themes. Novelium says its AI never writes or rewrites your prose. Galley (€199 once, runs in the browser) doesn't use AI to write either, and it doesn't let AI read your manuscript at all.
Novelium is closer to Galley than most tools on this site, because it also keeps AI from writing your prose. The difference is in how it checks your book. Novelium's continuity checking works by having an AI read your whole manuscript, including the characters, timeline and world details, so it can flag where they contradict each other. A lot of writers find that useful, especially for a long series.
Galley doesn't use AI for anything involving your writing, including reading it to check it. The checks it does run, like overused words, name consistency and pacing, are regular code that looks at your text. If you need continuity checking across a series, Novelium is the better choice. If you don't want any AI reading your manuscript, Galley is.

What both tools promise about AI
Novelium promises its AI will never write for you, and that's a good promise, because it means your prose stays in your own voice. Galley makes the same promise and also doesn't let AI read your book. Novelium can't offer that second part, because its continuity checking only works if an AI reads the manuscript.
What Novelium does that Galley won't
Novelium can notice when a character's eye colour changes between chapter 3 and chapter 40, or when the timeline contradicts itself across a series. That needs an AI that has read the whole manuscript, which Galley doesn't allow. If you're happy for an AI to read your book in exchange for those checks, Novelium is worth a look.
Choose Novelium if…
- You want AI to check continuity across a long book or a series
- You'd like a character dashboard and world codex built from your prose
- You're fine with an AI reading (but not writing) your manuscript
Choose Galley if…
- You don't want any AI reading or touching your writing
- You'd rather pay once than pay a subscription based on how much AI analysis you use
- You want to write and export the finished book (trim-size page, print PDF, EPUB, KDP preflight) in the same tool
Common questions
Does Novelium write or rewrite your prose with AI?
No. Novelium’s own site says it “never writes for you — not a single sentence, paragraph, or chapter.” Galley and Novelium are the same on that, which isn’t true of most AI writing tools.
So what’s the difference, if neither one writes for you?
It’s about what the AI is allowed to do. Novelium’s AI reads your whole manuscript to find timeline and character inconsistencies. That’s useful, but it means an AI is reading your book. Galley doesn’t let any AI read, generate or train on your writing. Its checks, like overused words and name consistency, are regular code, not a model reading your prose.
Does Novelium make a print-ready book?
Novelium says it exports PDF, EPUB and DOCX with embedded fonts, trim sizes and ten book themes, so it does more formatting than most drafting tools. It doesn’t mention a KDP preflight check. Galley has one built into its export.
