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
When you scan a chapter, the AI reads it like an attentive editor. It leaves marks: color-shifted phrases that caught its attention. Not errors. Observations.
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. Type a short explanation and the AI saves it. Next time it sees that pattern, the mark doesn't appear.
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. Review it from the gear menu.
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 in the manuscript. A small pill appears:
Ask AI opens the AI reader on your selection. It tells you what it notices, and "Rewrite this" generates a revision.
Later flags the selection for audit mode. No AI, just a bookmark.
author marks override system marks on the same text. your attention takes priority.
The big picture
Audit mode (gear menu) shows every mark as a card, grouped by chapter, with category filters at the top.
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.
Full scan reads every chapter. Takes longer, gives you recurring patterns across the whole manuscript.
Getting it out
Gear menu → export (Pro). Builds a Word document with all your revisions and author marks included.
your manuscript stays in your browser the whole time. export is the only moment it becomes a file again.
