For authors in progress

A partner for the book
you’re still writing.

Critique Partner reads your chapters and gives you the kind of feedback a good editor would — warm, specific, and aware of the whole book. As you submit chapters, it quietly builds a story bible and timeline of your characters, places, and threads, so it can tell you when something drifts. A whole library of partners comes ready to read — craft specialists and a reader for every genre — and you can build your own when you want a different ear.

What it does

A library of partners, a living story bible.

I.

A library of partners, each with a voice

Craft specialists — developmental, line, dialogue, pacing, continuity, and more — plus a genre reader for every shelf, from fantasy to literary. Or design your own: answer a few questions and a wizard drafts the prompt for you.

II.

A bible — and a timeline — that grow themselves

Characters, locations, plot threads, recurring objects, each linked back to the passage that established it — plus a timeline that lays your story’s events out in order. The bible you would keep yourself, if you had the time.

III.

It tells you when something drifts

A character’s eye color shifts; a timeline tangles; a thread is left dangling. See exactly where, then resolve in one click — update the bible to match, or dismiss it and keep your version.

Meet the partners

A reader for every angle.

More than a dozen partners come ready — craft specialists and a genre reader for every shelf — each with its own focus, voice, and house style. Pick the ones you want for any given chapter, or design your own.

Big-picture

Developmental Partner

Warm and perceptive. Asks probing questions about structure, arcs, scene purpose, pacing, and emotional truth. Speaks in paragraphs.

  • Does this scene earn its beats?
  • Where does the tension sag?
  • Do the actions follow from who these people are?

Sentence by sentence

Line Partner

Precise and attentive, with an ear for rhythm. Catches repetition, weak verbs, tags doing too much, POV drift. Quotes the line.

  • Repetition within close range
  • Telling that should be showing
  • Sentence rhythm and shape

Knows the whole book

Continuity Partner

Methodical and librarian-calm. Cross-references the bible. Notices voice drift, timeline tangles, plot threads quietly going unhonored.

  • Has this character’s voice drifted?
  • Do the durations actually add up?
  • What open threads is this chapter missing?

An ear for dialogue

Dialogue Partner

Alert and attentive, with a stage-actor’s love of voice. Listens for who’s really speaking, the subtext under the words, and lines doing too much — or too little.

  • Can you tell who’s speaking without the tags?
  • Is the subtext doing the work?
  • Is anyone saying what they’d never say aloud?

Where it goes next

Next Steps Partner

Warm, energized, a true collaborator. Reads for what wants to happen next, which threads are ripe for payoff, and how to get unstuck — in possibilities, never prescriptions.

  • What scene wants to happen next?
  • Which threads are overdue for a payoff?
  • Where could the story surprise — and still feel earned?

A reader for your shelf

Genre experts

Fantasy, sci-fi, mystery, thriller, horror, romance, historical, literary, contemporary — each reads with its own shelf’s conventions in mind, then helps you bend them.

  • Does your world — or your whodunit — hold together?
  • Is the genre’s promise being kept?
  • Where can you break the rules on purpose?

Custom · example

The Brooklyn newspaperman

Plainspoken, no ornament, suspicious of any sentence that sounds like it’s trying. Reads dialogue out loud in his head.

  • Is anyone here actually saying that?
  • Why two adjectives when one will do?
  • What’s the verb doing for its keep?

Built by you

Add your own

Beyond the ready-made library, add as many partners as you like — each with the voice, focus, and house style you want. The Brooklyn newspaperman is just one example; yours could be anything.

  • Built from a short questionnaire
  • Or pasted in from your own prompt
  • Reusable across every project

Continuity, by design

A bible worth keeping.

Every chapter you submit teaches the bible a little more about your book — who your characters are, where the story lives, the threads still unresolved, the objects that keep appearing, the way time moves. Each fact is anchored to the passage that established it.

When a new draft contradicts what the bible holds, you see exactly where — and choose, in one click, how to resolve it. The bible updates with you, never behind your back. A companion timeline lays every dated event out in order, so a week that should have passed can’t quietly become an afternoon.

For non-fiction, it tracks your people, terms, and timeline — and catches you contradicting yourself in chapter nine.

Already finished a draft? Import the whole manuscript and Critique Partner builds the bible and timeline for you — a continuity pass for a book that’s already written.

  • Locations
  • Plot threads
  • Timeline events

    In bible:

The kind of feedback a good editor gives — warm, specific, and aware of the whole book.

The Critique Partner promise

How it works

Three steps. Then quiet.

  1. Start a project

    A title, a genre, a note about the book if you like. Run as many books as you want — each gets its own bible and its own history.

  2. Submit a chapter

    Paste your draft. A live word count and a cost preview show what you’re about to send. Pick which partners read this chapter — every submission becomes a new version; earlier drafts stay in your history.

  3. Read the critique

    Findings from each partner, grouped by severity. Resolve any bible drift inline. Revise when you’re ready — the bible follows along, and past critiques stay readable next to the new one.

Your book is yours.

We never train AI on your writing — and neither do the leading models we build on. Your chapters are encrypted in transit and at rest, private to your account, and never sold or shared. The critique system that reads them is our own.

What it costs

Credits, nothing surprising.

Each critique costs credits — more for long chapters or many partners, fewer for shorter passes. Plans include monthly credits; top up whenever you need. You see the exact cost before you submit, and a running ledger shows where every credit went.
