novel is built.
An AI editor that reads your whole book, and never writes a word of it.
A novel is a structure. At launch, you upload yours and RedPencil maps the whole of it: where the acts turn, where a thread goes slack, where a character stops holding weight. It shows you the shape of the book you actually wrote.
At launch, your first chapter is read free.

How it works
From manuscript to marked-up, in four steps.
No setup and no plugins. At launch, you upload the file you already have.
STEP 01
Upload
Drop in your .docx, .pdf, .epub, .md or .txt file. Up to 350,000 words: the whole book, not a sample.
STEP 02
We read everything
Tell us what the book is meant to be first. Then the AI editor reads it cover to cover, every chapter and every thread, so you (or your human editor) start from a map of the whole book.
Intent brief: “Aurel’s absence is deliberate. Protect it.”
STEP 03
Your Editor’s Desk
Four reports arrive, plus comment pins set right in your manuscript margins.
STEP 04
Talk it through
Click any pin to open a conversation. The editor advises; you keep every decision.
What you get back
Four documents, one honest read.
Every note cites chapter and page, and says which kind it is: a fact on the page, an inference from the evidence, or an editorial judgment. Nothing is rewritten for you; the words stay yours. see Sample reports, Editorial Letter, Ch. 11, p. 162

Editorial Letter · 12 pages · excerpt · Sample report
Dear writer,
I read The Cartographer’s Daughter twice: once straight through, then chapter by chapter against your intent brief. The good news first: your premise is fresh, and Elena is a protagonist I trusted from the first page. The map-as-memory motif in Ch. 3, p. 38 is the kind of image most novels never earn.
Where the book asks the most patience is the middle. The midpoint reversal, the torn corner, lands beautifully, but Act II makes the reader wait more than sixty pages for it. Three changes would raise the whole manuscript:
- Bring the torn corner forward. Move the discovery from Ch. 11, p. 162 to Ch. 8, p. 119. Elena’s aimlessness in Ch. 8–10, pp. 119–160 reads as the book’s, not hers.
- Let the father speak sooner. He’s the emotional engine but stays offstage until Ch. 14, p. 212. One scene in Act I would make the ending devastating instead of merely sad. His long absence may be intentional; if so, give the reader one early moment that makes them feel the gap, so it reads as a choice rather than a delay.
- Trust your endings. You explain the final image three times (Ch. 22, pp. 336–339). Consider keeping one. Readers are smarter with you than you’re letting them be.

Chapter 14 · The Atlas Room
Elena unrolled the map across the table, the parchment still curling at its edges. She traced the ridgeline with one finger, her green eyes narrowing at the gap where a river should have been.
“It ends here,” she said, though the word ends felt wrong in her mouth. Maps did not end. They waited.
Behind her, the door opened without a knock, and she did not need to turn to know the sound of her father’s boots.
