Who wrote this: the Vellam team. We build a competing tool, so treat any comparison here as an interested party talking. Everything stated about Novelium is taken from what Novelium publishes about itself, checked on 20 August 2026, and every claim below can be verified on its own site or in the app stores. Where the public record runs out, this page says so instead of filling the gap.
Short answer: yes, Novelium is an AI tool, but of the reading kind rather than the writing kind. Its own tagline is “It reads. It never writes.” It analyses a manuscript you already wrote and flags timeline conflicts, character inconsistencies, plot continuity breaks and information-flow problems. It does not draft scenes, rewrite your sentences or suggest plot changes. If your question is really “will this write my book for me”, the answer Novelium gives is no.
What Novelium actually is
Novelium is a writing environment with an analysis layer on top. You can import a draft from Word, Scrivener, Google Docs or plain text, or start on a blank page, and write in its editor. While you write, it tracks characters, locations, world rules and dates, and raises issues in a sidebar.
Its four named checks are:
- Timeline conflicts, for example a duration that cannot fit the dates you gave it.
- Character inconsistencies, for example a character who appears after being written out.
- Plot continuity, for example an object that quietly changes description between chapters.
- Information flow, for example a character acting on something nobody has told her yet.
Around that sit a character dashboard, a World Codex for lore and rules, a timeline view, beta reader sharing with inline comments, and a book design module that exports print-ready PDF, EPUB and DOCX. The book design part is free on every plan.
So does Novelium use AI, and where does it draw the line?
It does. Reading a novel and understanding that a character is dead in chapter eight is a language-model job, not a spellcheck job. The distinction that matters for authors is not whether a tool uses AI, it is what the AI is allowed to touch.
Novelium publishes five explicit limits, in its words, under the heading “Five Things Novelium Will Never Do”:
- Write or suggest a single line of your story
- Send your work anywhere unencrypted
- Train on your manuscript or learn from your writing
- Make a creative decision on your behalf
- Hand your data to a third party
That is a clearer promise than most tools in this category make, and it is the same category Vellam sits in. Neither tool is a co-writer.
One correction to a claim that circulates in AI-generated summaries of Novelium: it is not a local-only tool that never touches the cloud. Its own site describes encrypted, “privacy-first processing” and a browser app at app.novelium.com, alongside desktop and mobile builds. Encrypted and never-trained-on is a real commitment. Never-leaves-your-machine is a different commitment, and Novelium does not make it.
Is Novelium legit?
It is a real product, not a landing page with a waitlist. What follows is the verifiable record as of 20 August 2026, with both sides of it.
What checks out. There is a named founder with a public origin story: a cybersecurity professional who started a novel, lost track of his own timeline and built a tool to find his way back. The App Store lists the developer by name, Bradley Jay Tenenholtz. There are shipping apps on more than one platform: a web app, an iOS and iPadOS build, a macOS build for Apple silicon, a visionOS build and an Android app. The iOS app was at version 2.11.7 when we checked, which is the release cadence of something actively worked on rather than abandoned. Pricing is published openly, with a free tier that needs no card. Support runs through a public Discord.
What is thin. The iOS listing carried 3.7 out of 5 from 12 ratings, so there is no meaningful body of user reviews yet in either direction. The independent review record is similarly small: the company’s own Academy runs to roughly 600 pages, but third-party coverage that is not a directory listing is hard to find. Its own blog had three posts. The desktop download page warns, in its own words, that “Windows and macOS don’t recognise it yet and will show a security warning”, which means the desktop build is not code-signed the way an established vendor’s would be. That is normal for a new independent app and it is not evidence of anything bad; it is a thing to know before you click through a warning.
One thing to check for yourself. The testimonial block on the Novelium home page attributes a quote to “James Patterson, Bestselling Author”, next to two testimonials credited by first name only. We could not independently corroborate that attribution, and we are not asserting anything about it either way. The general rule is worth more than this one case: a celebrity name on a marketing page is not a verifiable signal for any tool, ours included. Ratings, refund terms, a readable privacy policy and your own trial run are.
None of that adds up to “avoid”. It adds up to “young product, verify the current state yourself, and do not take a marketing page as documentation”.
How much does Novelium cost?
Published pricing on novelium.com, checked 20 August 2026:
| Plan | Price | What you get |
|---|---|---|
| Free | $0 | One project, one device at a time, 10,000 analysis words per month |
| Basic | $7 / month | Unlimited standalone projects, all your devices, 100,000 analysis words per month |
| Pro | $19 / month | Unlimited projects, series workspaces, cross-book tracking, 2,000,000 analysis words per month |
| Premier | $39 / month | 20,000,000 analysis words per month, in-app only |
| Publishing | $147 / month | Unlimited analysis words, in-app only |
The number that decides your plan is the word meter, not the price. Analysis words are consumed by how much text you run through the checks, and a full novel is a big meal. Take a 90,000-word manuscript:
- On Free, 10,000 words a month means you cannot analyse a full novel in a month at all. It is a look around, not a pass over your book.
- On Basic, 100,000 words a month is roughly one full pass, once. If you revise chapter twelve and want the book re-read, you wait for the reset.
- On Pro, 2,000,000 words a month is about twenty-two full passes, which is the first plan where re-reading the whole book after every revision round stops being a calculation.
If you buy through the iPhone or iPad app instead of the website, Apple’s in-app prices are higher: Basic at $10.99 a month, Pro at $29.99 a month, Pro at $289 a year, plus theme packs at $3.99. Same product, so subscribe on the web unless you have a reason not to.
For contrast, since this is a page written by a competitor and you should know where the bias points: Vellam is a one-time payment with credits that do not expire, so a re-run after a revision round costs credits you already own rather than a monthly allowance you have to wait out.
The three questions to ask before you upload anything
These apply to Novelium, to Vellam and to every tool in this category. Ask them of the current version of the site, not of a blog post:
- What does it store, and where? A manuscript uploaded for analysis is a copy of your unpublished book on someone else’s server unless the tool states otherwise.
- How long does it keep it, and can you delete it? Look for an actual delete path, not just a promise of privacy.
- Is your text used for training? Novelium’s answer is a clear no, published on its home page. Get the same answer in writing from anything else you try.
How this compares to Vellam
The two tools share the core promise, so the honest summary is short. Both read the novel you wrote and neither generates prose for you. Novelium is a subscription metered by analysis words, with a strong writing-environment surface: editor, world codex, beta readers, and free book design and export. Vellam is a one-time payment with credits that never expire, and it adds a Story Atlas built from your chapters, whole-book consistency checks, a built-in detector that scores how AI-like your prose reads, and a free rule-based prose layer for cliches and weak verbs.
The full feature-by-feature breakdown, including where Novelium is ahead, lives in the Vellam and Novelium comparison.
Frequently asked questions
Is Novelium AI?
Yes, and it says so. Novelium uses AI to read and analyse a manuscript you already wrote, catching timeline conflicts, character inconsistencies, plot continuity breaks and information-flow problems. What it does not do is generate prose: its own tagline is “It reads. It never writes.” If the worry behind the question is that a tool will put words you did not write into your book, Novelium is not that kind of tool.
Does Novelium write for me?
No. Novelium states it will never write or suggest a single line of your story, and never make a creative decision on your behalf. It flags where the facts of your story stop lining up and leaves the fixing to you.
Is Novelium legit?
It is a real, actively developed product with a named founder, published pricing, a free tier that needs no card, and shipping apps on web, iOS, iPadOS, macOS, visionOS and Android. It is also young: 3.7 out of 5 from 12 iOS ratings at the time of writing, little independent review coverage, and a desktop download that its own site warns will trigger an unrecognised-app security prompt because it is not code-signed as an established vendor would be. Verify the current state yourself and try the free plan before subscribing.
How much does Novelium cost?
Free with one project and 10,000 analysis words per month, Basic at $7 a month for 100,000 words, Pro at $19 a month for 2,000,000 words, Premier at $39 a month for 20,000,000 words, and Publishing at $147 a month for unlimited words. Buying inside the iPhone app costs more: $10.99 for Basic and $29.99 for Pro per month. Prices checked on 20 August 2026, so confirm on the current site.
Does Novelium store my manuscript in the cloud?
Yes. Despite summaries that describe it as local-only, Novelium runs a browser app and syncs across devices, and describes its handling as encrypted with privacy-first processing rather than as processing that never leaves your machine. It states your manuscript is never used for training.
Does Novelium work for novels written in Polish, German or Spanish?
Novelium says it reads manuscripts natively in more than 30 languages, and lists Polish, German and Spanish among them. That is a claim on a marketing page rather than something documented in help articles, so run a chapter through the free plan in your own language before you commit. Vellam’s interface and analysis are shipped and localized in Polish, English, German and Spanish.
Is Novelium the same as Vellam?
Close in principle, different in shape. Both read your novel and never write it. Novelium is a subscription metered by analysis words with a broad writing environment around the checks. Vellam is a one-time payment with credits that never expire, and adds a Story Atlas, an AI-writing detector and a free rule-based prose layer. The side-by-side comparison goes through it row by row.
