From the praxis
You read the praxis. Here is what I built after it.
The praxis names what AI rewriting normalizes when it tries to improve prose. Rewriter is the second draft. It reads first, mends only at seams the writer accepts, and refuses to push when there is nothing to fix.
Weaver works in scenes. Rewriter works in seams. R/W works in marks.

Stage two of three · Kaizen Rewriter
Where the weave becomes a draft, chapter by chapter.
A pass through the whole manuscript.
Bring the weave from Weaver, or any draft you have. Rewriter reads the manuscript as a whole, drafts a vision back to you, and works through it a chapter at a time. Your dictionary and voice carry forward. When the draft is coherent, hand it to R/W for the editorial reading.
01 · How Rewriter works
Four stages. Roughly.
Four stages. Roughly.
You can skip any of them.
Most rewrites move through the same shape: read the manuscript whole, decide what each chapter is doing, rewrite chapter by chapter, hold the lines and facts that earn it. Rewriter makes that shape visible and lets you wander off it whenever the work demands.
Stage 01 · Vision
What is the piece actually doing?
Before any line edits, Rewriter does a vision pass: a short, plain reading of what the draft is about, what it seems to want, and where it's quietly working against itself.
You pick a voice source first: your own past work, a target essayist, a house style, or none at all. The vision pass is rendered through that lens.

What this piece is doing
An attempt at a portrait of a city by way of its river, the river doing most of the work, the city standing back. The opening is patient; the middle drifts; the ending lands hard, but maybe too hard.
Working against itself
The narrator wants to disappear. The metaphors keep pulling them back into frame. Pick one.
Stage 02 · Outline
Intents, per chapter.
From the vision, Rewriter drafts a short list of intents for each chapter: the goals the rewrite should satisfy. Click any row to edit. Drop one that doesn't match. Add one that's missing.
Intents keep the rewrite accountable. The supervisor reads each chapter against its intents, drops the lowest-priority intent on retry, and falls back to keeping the original when every intent has been pulled. The writer's draft is the baseline; the rewrite has to earn its place.
Outline · 14 chapters
Chapter 1 · the river arrives
- Establish Mara's observer stance before the bell motif arrives
- Hold the river's quiet arrival; resist the urge to overshow
- End on the chair-by-the-window image, not on commentary
Chapter 2 · the bell tower · editing
- Mara's separation from the bell ritual, shown through what she's not doing
- Pull the third bell forward; it's doing too much late
- Clean exit on the platform; no narrator reflection
Chapter 3 · the storm finds the bell
3 intents
⏎ accept · E edit · D drop · + add intent
Stage 03 · Rewrite
Side by side. Chapter by chapter.
The original on the left. The rewrite on the right. You accept or retry chapter by chapter; the supervisor reads each one against its intents and either passes the rewrite, asks for a retry, or keeps the original. Every kept chapter has an undo a click away.
Hold a passage verbatim to lock it. Add a voice note to push the rewrite in a direction. Watch the ripple thread updates forward and back to the chapters that depended on what you just changed.
Original · ch. 2
The river didn't arrive at the city so much as wander into it, the way a stranger drifts into a room and waits to be noticed.
By the time anyone looked up, it had already taken a chair by the window.
The water was the color of weak tea, and ran the way a sentence runs when its writer is tired.
Rewrite · in your voice
The river arrived at the city the way a stranger arrives at a party: late, and certain it had been invited.
By the time anyone looked up, it had taken a seat.
The water was the color of weak tea, and moved like one.
Stage 04 · Control
Three small instruments
Three small instruments
for keeping the pen.
The rewrite view has three side panels you can call in when you need them. Most days you won't. Some days they're the whole reason the tool works.
Holds
Facts and lines
Facts and lines
that are already right.
Pin a passage verbatim or a fact about a character, a world rule, or a piece of continuity. Rewriter rewrites around them. Useful for the line that sets the tone, the rule the world cannot break, and the timeline you've already worked out.
Voice notes
Tell the rewrite
Tell the rewrite
what you want.
Highlight a passage on either pane and add a short note. More like this. Less wry. Drop the metaphor. Notes flow into the dictionary as voice-scope entries the rewrite has to honor on the next pass.
Ripple
Only what depends
Only what depends
on what you changed.
Keep a chapter and Rewriter quietly proposes updates to the chapters that referred back to it, forward and back. Nothing else moves. Pip indicators on the rail show which chapters carry incoming ripple.
The writer's draft is the baseline. The rewrite has to earn its place. If it doesn't, the chapter you finished yesterday is still the chapter you finished yesterday.

02 · A short list
How Rewriter behaves.
Rewriter waits for a finished draft. The cursor in Rewriter is the same cursor you started the morning with; the writing happened before you opened the tool.
Rewriter works from what you already wrote. Bring a first pass and Rewriter has plenty to do; come without one and there's nothing yet to read.
Rewriter is for the bigger questions: shape, pacing, the line that drags, the chapter that lands flat. Sentence-level cleanup tools run alongside it perfectly well.
Rewriter shows its reasoning. Every proposed change comes with the editorial logic behind it, visible and argued with on the page.
03 · Who Rewriter is for
Writers with a draft that almost works.
Rewriter is for the writer with a finished draft who wants a manuscript-wide pass, with the reasoning visible at every step.
- Novelists going into their second or third pass
- Authors who finished a draft and need someone to hold it accountable
- Writers who want a rewrite they can argue with
- Indie authors revising before they hand the manuscript to an editor

05 · Common questions
Things people ask before
Things people ask before
they sign up.
How does the voice source work, exactly?
You point Rewriter at a body of writing: your own archive, an essayist you admire, a house style guide. It builds a small profile of cadence, sentence shape, and word preferences, and uses it to bias every rewrite. You can switch sources mid-document. Your text is never used to train the model.
Does it work on long pieces?
Yes, chapter at a time, manuscript-aware. Rewriter holds the whole book in context: a critique on page 240 can refer back to a thread laid down on page 12. For very short passages where you're choosing between drafts, see Weaver.
What about confidentiality?
Your drafts are not used for training, full stop. They live in your browser, never on our servers. Purge any draft and its profile from one screen and the work leaves with the same keystroke.
Can I use it without the rewrite stage?
Yes. Some writers use Rewriter only for the vision pass and the critique, and rewrite by hand from there. That's a valid loop and the tool is built to honor it.
Does it talk to R/W?
Rewriter exports a bundle (manuscript plus dictionary) for the next stage; the receiver in R/W is shipping next. Rewriter and R/W share a vocabulary, marks, voice notes, dictionary kinds, so when the bundle import lands, the editorial memory the writer built in Rewriter travels forward. For now, the export is ready; the matching import on the R/W side is on the way.
