A fascinating tool, recommended to me by a colleague in the industry. It delivers deeply considered feedback with a handy breakdown by chapters and areas of work. I recommend it to the authors I collaborate with as their first beta reader, and to editors as a supporting tool that generates ideas.
The writing tool that knows every chapter.
Vellam reads your novel chapter by chapter. It catches character inconsistencies, tracks plot threads, and tells you exactly what doesn't work. Before your editor does.

Vel — character consistency Minor inconsistency
Vel's reaction to Isu's return is consistent with his analytical nature. At the start of the chapter, Vel is struggling with the heat — moments later it turns out he's wearing a jacket. Worth explaining why he didn't take it off.
Pyroprojector malfunction Suggestion
The description of Mount Heron's disaster is vivid. The transition from the malfunctioning device to the narrator's account is abrupt — one sentence about image stabilization would suffice.
Living room in Vel's home Consistent
The marble sofa 'pulled from the earth' consistently corresponds to the bedroom description from chapter 1. Worth clarifying the spatial arrangement: is Isu speaking from the kitchen, or are they side by side?
The Problem
Writing a novel is
a lonely sport.
Every writer knows the pain. No one looks over your shoulder. And sometimes that's exactly what you need.
You don't remember what you wrote in chapter 7
At 80,000 words, no one can hold every detail in their head. And then a character's eye color changes.
Beta readers get back to you in weeks — or never
You're left sitting with your manuscript not knowing if it's a good story or just feels that way.
Other tools don't know your book
You ask a chatbot for feedback and get a context-free answer. It doesn't know that Mark died in chapter 5 or what the magic rules are in your world.
You feel something's off — but you don't know what
Writer's block isn't a lack of words. It's a lack of certainty. Vellam tells you specifically what needs attention.

What
users say
I was skeptical about "AI for writers", I expected yet another tool that would tell me my sentences are too long. Vellam actually tracks plot threads. It showed me that the subplot with Detective Nowak disappears after chapter 14 and never comes back. I had it in my head, but I couldn't see it on "paper".
The text analysis made a positive impression on me. You could see exactly what needed improvement and what was missing. Unlike typical AI, the tool picked up on the very things I myself felt needed polishing. I like that it automatically detects characters, analyzes geography and other elements that a person wouldn't normally notice on their own.
Vellam pointed out things none of my beta readers noticed, for example, that one of the characters appears in chapter 8 as if the reader already knows her, but I don't actually introduce her until chapter 11. A minor detail, but exactly those details knock you out of the reading experience. I also got a great thread map that made it clear I was wrapping up three plotlines too quickly.
I self-publish my books, and before Vellam, every editing round was a logistical nightmare: notes in Word, margin comments, an Excel spreadsheet for plotlines, plus sticky notes with a timeline on the wall. Now I have it all in one place, and more importantly, in a format that can actually be used.
I used to wait two, three months for feedback from beta readers, sometimes longer, because everyone has their own life and reading someone else's text isn't always a priority. With Vellam I got specific, actionable feedback in a matter of minutes.
FAQ
Questions from
writers
How long do I have to wait for the text analysis?
A few minutes. Seriously. Instead of waiting weeks for feedback from beta readers, you get a detailed editorial report the same day.
What format should my text be in?
You can import a ready-made .txt, .docx, or .pdf file, or create a book from scratch directly in Vellam. You add and edit chapters in the built-in editor.
How do I prepare my file to get analysis for each chapter?
Every new chapter must start with a numbered heading, e.g. "Chapter 1", "Chapter 2". That's it. Vellam does the rest.
Can I edit the text after submitting it for analysis?
Yes — Vellam has a built-in editor where you can edit chapters and save changes at any time.
What is the Story Bible?
It's where you describe your book before starting the analysis. Characters, style, genre, plot assumptions — Vellam uses this data in every analysis so the feedback is precisely tailored to your story, not generic.
Is Vellam a novel writing program?
Vellam is more than an editor. It has a built-in text editor, but its strength is analysis: it knows your manuscript, characters, and world rules from the Story Bible and gives concrete feedback like a beta reader with an elephant's memory.
How is Vellam different from other AI writing tools?
Most AI tools treat every query from scratch and simply don't know your story, characters, or world rules. Vellam builds a Story Bible: a permanent knowledge base about your book that every analysis draws from. It's like talking to someone who's actually read your manuscript instead of seeing it for the first time.
Will Vellam train AI on my manuscript?
Never. Your text is not used to train any models. We store data only to provide the service and you can delete it at any time.. See our privacy policy.
How do credits work — do they expire?
Credits have no expiry date. Pay once and use whenever you want — this year, next year, when you finish one volume and start the next. One package (from $9.99) is enough for several full novel analyses.
What language does Vellam work in?
Vellam works in Polish, English, and German — interface, analysis, and support. It's the first dedicated novel-writing tool available in three languages.
