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'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.
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.
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?
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.
A writing tool
that truly knows
your story.
Story Bible: Vellam knows your world
Define your characters, rules, locations, and style once. Every analysis uses this knowledge instead of reinventing it.
Story Atlas: every character, location, and thread chapter by chapter
Vellam builds detailed cards for every story element, separately for each chapter. See how characters evolve, locations gain importance, and threads develop.
Plot consistency and open threads
Vellam tracks threads, detects logical gaps, and points out where the narrative loses momentum. Before your editor does.
Character voice and behavior consistency
Checks whether characters speak and act consistently throughout the manuscript. No more accidental personality changes.
Built-in editor with contextual analysis. Write and analyze in one place
Import .docx, .txt, or .pdf. Write new chapters directly in Vellam. Every analysis considers the context of the entire book, not just a single excerpt.
Feedback loop: Vellam learns your decisions
Mark each suggestion: accept / consider / not applicable — with a reason. On the next analysis, Vellam won't repeat rejected suggestions and knows the context of your choice.
Built-in assistant
Write and ask questions instantly. No window switching. No context loss.
Refine your style, bring every scene to life
Select a passage and say what you want changed. Vellam will rewrite it with more sensory detail, expand descriptions, or apply the "show, don't tell" principle.
Analyze the entire book at once
No need to go chapter by chapter. Vellam will run through the entire manuscript in one pass and find patterns that aren't visible in a single excerpt.
Static analysis of every sentence
Nine layers of style and readability: clichés, fillers, long sentences, passive voice, weak verbs, adverbs, repetitions, dialogue vs narration, and the fog index. Click a statistic and jump straight to the flagged passage.
Focus mode: one chapter, one screen
Open a specific chapter and switch on focus. The rest of the book disappears from view, leaving only the passage you're working on.
Research on demand
Writing about time travel, a machine uprising, or Mars colonization? The assistant finds and synthesizes the scientific and historical knowledge you need to write with confidence.
Chapter summaries
Vellam generates a concise synopsis for each chapter. Ready for a query letter, pitch, or your own notes.
Pacing analysis with a chart
A visual chart of narrative tension across the entire book. Instantly see where the story slows down.
Every character. Every location. Every thread.
Chapter by chapter.
Vellam builds detailed cards for every element of your story, separately for each chapter. See exactly how characters evolve, which locations gain significance, and how threads develop.

Vel really just wanted to leave already.
The door was closed by someone unseen, whom no one had heard or noticed.
He muttered quietly under his breath.

Notes that stay in the text.
Highlight a passage or a whole chapter and leave a note. Vellam remembers where you left it and brings you back the next time you open the book.
That evening she walked to the old house on Cherry Lane, though she knew no one was waiting there anymore. The house was silent. So was she.
Ch. 2 calls it "Linden Street". Unify the street name.
Check the amulet motif. Did it disappear after Ch. 4? Anna mentions it in Ch. 2 and then nothing.
Comes back in Ch. 12. Keeping it.
