Galley vs. Novelium
Last reviewed July 2026
The facts first: Novelium (subscription, $0–$19/month on its listed tiers, up to $147/month for the highest add-on tier; browser-based) uses AI to read your manuscript and flag timeline, character, and plot-hole inconsistencies, plus a character dashboard, world codex, and export to PDF/EPUB/DOCX with book themes. It states plainly that its AI never writes or rewrites your prose. Galley (€199 one-time, web app) shares that no-generation rule but takes it a step further: no AI reads your manuscript at all, for any reason.
This is a closer comparison than most on this site, because Novelium has clearly drawn a line similar to Galley's: the AI counts and checks, it does not compose. That is a genuinely good line to hold, and their marketing is upfront about it. Where the two part ways is what "checking" is allowed to mean. Novelium's continuity engine works by having AI read your whole manuscript — characters, timeline, world details — to build the cross-references it flags inconsistencies against. For a lot of writers, especially on long series, that is a real and useful trade.
Galley doesn't make that trade. Its rule is that no AI touches your content in any capacity — not generating, not rewriting, not reading for analysis, not training. The checks it does run (overused words, name consistency, pacing) are plain deterministic logic against your text, not a model interpreting it. If continuity-checking across a series is the feature you need, that is Novelium's category to win. If you'd rather no AI process ever sees your manuscript, that's the whole reason Galley's rule exists.

The line both tools draw, and where it stops
Credit where it's due: Novelium's "never writes for you" promise is real and matters. It means the prose stays yours in the way that counts most to most writers — no AI voice creeping into your sentences. Galley draws the same line and then keeps going: not just "AI won't write your book," but "AI won't read your book, either." That's a stricter standard, and it's the one thing Novelium's continuity engine can't offer by design, because the feature only works if an AI is reading.
What Novelium does that Galley won't
Catch a character's eye colour changing between chapter 3 and chapter 40, or a timeline that quietly contradicts itself across a series. That requires an AI with the whole manuscript in view, which is exactly what Galley's rule rules out. If that safety net is worth an AI reading your book to you, Novelium earns its case.
Choose Novelium if…
- You want AI-assisted continuity checking across a long book or series
- A character dashboard and world codex built from your prose is worth having
- You're comfortable with an AI reading (not writing) your manuscript
Choose Galley if…
- You want a hard guarantee that no AI, anywhere, ever touches or reads your content
- You'd rather pay once than meter a subscription by analysis words per month
- You want the finished book — trim-size page, print PDF, EPUB, KDP preflight — from the same tool you drafted in
Common questions
Does Novelium write or rewrite your prose with AI?
No, and they are explicit about it: their own copy says it "never writes for you — not a single sentence, paragraph, or chapter." On that specific point Novelium and Galley agree, and it is worth saying plainly since most AI writing tools do not make that promise.
So what is the actual difference, if neither one writes for you?
What each AI is allowed to touch. Novelium's AI reads your whole manuscript to catch timeline and character inconsistencies — that is real value, but it means an AI is reading your book. Galley's rule is stricter: no AI reads, generates, or trains on your content, full stop. Its checks (overused words, name consistency) are plain non-AI logic, not a model reading your prose.
Does Novelium make a print-ready book?
Its own pages describe PDF/EPUB/DOCX export with embedded fonts and trim sizes, and ten book themes — a real formatting feature, closer to Galley's territory than most drafting tools. It does not mention a KDP preflight check. Galley's export includes one before you upload anywhere.
