Everything the reader knows how to do.
^ keep this open the first time through. you'll want it.
Getting started
Paste your manuscript, upload a file (.txt, .md, or .docx), or try the built-in demo chapter. The story should already exist. This tool is for revision, not drafting.
paste works best for a single chapter. upload for a full manuscript (it detects chapter headings automatically).
Chapters are split by headings like "Chapter One," "CHAPTER 1," "Prologue," or markdown headings. Paste without a heading and it loads as one continuous read.
The reading
As you read, the AI quietly tags passages it wants you to look at. Each one shows up as a color shift in the letters themselves. No boxes, no icons, nothing yelling at you. Some marks are tagged as suggestions, meaning the AI is less certain. They look the same at rest but carry a confidence level the system tracks internally. It adjusts what it flags based on what you keep and what you dismiss.
Click a mark to open its panel. Try it.
Four breaths. Four heartbeats. Four walls in my room.
I swung my feet out of bed and onto the carpet. Cool fibers pressed between my toes. RepetitionThe walls, the ceiling, the dusty morning light. Everything looked exactly the way it should on a lazy Saturday morning.
Parallel rhythm accumulating into post-image explanation: "The walls, the ceiling, the dusty morning light" lists three fragments in the same frame, then "Everything looked exactly…" restates what those details already implied.
Except Pacingthe hum was already there. Low and constant, so steady I almost mistook it for the house settling.
The shift from domestic calm to unease could land harder with a shorter lead-in. "So steady I almost mistook it" dilutes the strangeness.
It came from beneath the floorboards, more felt than heard.
Six categories. Click one to highlight its marks above:
Your moves
Open a mark above, then try these. They work here.
D is the one you'll press most. most marks are "yes, I see it, moving on."
A few more, once you're in the flow:
Teaching
Press T on a mark above, type a short explanation, and it saves. Next time the AI sees that pattern, the mark won't appear. Try it, then watch the dictionary below fill in.
The tool gets quieter the more you use it.
this is the whole point. first pass is noisy. third pass, only the real stuff is left.
The dictionary lives in your browser. Conditional rules let you scope entries to specific POVs, chapter ranges, or scene types.
Making changes
AI rewrite: Press Q on any mark. The AI streams a rewrite using its own reading as context. Edit the suggestion, then apply. Try it on the demo marks above.
Manual edit: Click the pencil, double-click, or press E. Try the paragraph below:
Both paths share the same undo stack, three levels deep. Edited paragraphs show a gold bar in the margin.
manual edits also offer a "Rescan" link in the toast. one click, the AI re-reads just that paragraph.
Your marks
Select any text below. A pill appears.
The road crumbled at the edges where rain had eaten through years of neglect. She kept to the center line, stepping over the cracks out of habit more than caution.
Ask AI opens the AI reader on your selection. Later flags it for audit mode, no AI involved.
author marks override system marks on the same text. your attention takes priority.
Flag and return
Press F on a mark and it doesn't disappear. It moves to a list you check later. Try it, then resolve it from the list.
She nodded once, the way she always did when she meant the opposite. VoiceIt was a kindness she'd inherited from her mother, the kind that took years to recognize.
Narrator stepping outside the moment to label the gesture instead of staying in it. Worth a second look.
The list lives at the top of audit mode under History → Queue. Flagged marks stay there until you handle them, across sessions.
flag is for "I want to think about this." dismiss is for "I've decided." different muscles.
The big picture
Five groups. Click the tabs:
D/T/F/Q work on audit cards the same as reader panels. check a box to build a beta reader packet.
The heatmap is the thin rail on the right edge. Each dot is a mark. Clusters mean dense sections.
Chapter sidebar appears when you hover the left edge. A table of contents slides out with scan status per chapter and expandable mark sub-lists.
Full scan reads every chapter and returns cross-chapter findings: phrases that repeat, motifs that track, continuity slips the per-chapter scan missed.
Inline context
Click the pills below a chapter heading. Click the chevron at the end of the last paragraph.
The sky had been bruised all morning. She stood at the window watching it darken.
She sat on the porch step and pressed the phone to her ear. Nothing.
He hadn't called in three days.
Scene breaks show the scene type and pressure shifts. Density toggles in the TOC let you turn each family on or off.
vessels mount lazily as you scroll. the tool isn't building hundreds of panels you'll never see.
Passes and runs
Pick a lens before you scan. Each one changes what the AI looks for:
Each time through, the tool logs a reading run. The rest of the toolkit builds on that history:
Snapshots save the manuscript state before a big change. Analytics compare two runs: word count deltas, density shifts, which flagged marks got addressed. Journal logs every edit chronologically. Queue promotes flagged marks into a tracked task list. Recurrence clusters the same pattern across chapters so you can handle the group at once. Summary brief is a short editorial letter about the whole book, with citations.
flag a mark in the queue, fix it, check it off in the journal.
Developmental reading
Pro unlocks a second toolkit. Every scene the AI reads gets a card. Click any field to edit it:
That's one piece. The full toolkit: tension arc curves pressure across every chapter with TOC sparklines. Continuity ledger tracks characters, objects, locations, and flags contradictions. Setup and payoff watches what you planted, what paid off, and what's still dangling. Character pressure maps external, internal, relationship, and deadline weight per character per chapter. POV drift locks a baseline scene per POV character and flags when the voice shifts.
all of these live in the audit notebook now. open audit mode, pick the Structure, Voice, or Craft group.
Getting it out
DOCX export (gear menu, Pro). Word document with your revisions as native comments and a dictionary appendix.
Beta reader packet. Check findings in audit mode (try the checkboxes above), export a DOCX with only what you picked plus a cover page. Hand it to a reader without exposing the whole manuscript.
Beta reader feedback. Gear menu → Import → Beta reader feedback. Upload a DOCX with Word comments and they come in as marks. Preview before committing. D/T/F/Q work on them the same as AI marks.
feedback import works with any commented DOCX, not just ones originally exported from KRW.
Settings
Bottom-right corner of the reader.
Theme. Light or dark. Follows your system by default.
Tiers. Free uses Gemini on Google's paid API. Pro ($20/mo) uses Claude on Anthropic's commercial API. Both tiers run on paid APIs that don't train on inputs. Or bring your own key.
Dictionary. Everything you've taught the tool. Conditional rules let you scope entries to specific POVs, chapter ranges, or scene types.
Categories. Six built-in, plus custom categories you can create, rename, and recolor.
Voice profile. Dictionary, categories, and POV baselines bundled as a file. Export it when you start the next book.
Import. Bring back a previous DOCX export with mark recovery, or import beta reader feedback from a commented Word file.
Recent edits. All revisions in one place, regardless of source.
Audit mode. Opens the diagnostic notebook. Everything that used to have its own dialog (tension arc, scene cards, continuity, pressure, recurrence, analytics, queue, journal, snapshots) now lives in audit tabs.
The log
newest at the top. everything here is live.
Scans now wait until you open a chapter before using your budget. Marks that span paragraphs now resolve as one.
Polish pass across category toggle, cascade undo, and assorted reader details.

Beta reader packet export. Pick marks, export a DOCX with a cover page and only the comments you chose.
Beta reader feedback import. Upload a commented DOCX, get the comments back as reviewable marks.
