How to Edit a Book with AI: A Step-by-Step Guide
AI won't replace your editorial judgment, but it can carry out your changes in a fraction of the time. Six steps: get the text in, write a narrow instruction, pick one pass, read the changes, keep what works, export.
This is a guide to the method.
Looking for the editor itself — import a manuscript and get AI edits you keep or drop? That is Edit a Book with AI. Free to start, no credit card.
Open Edit a Book with AIStep 1: Prepare Your Manuscript
Editing works chapter by chapter, and the importer splits your manuscript into chapters for you. Four ways to get your text in (New book → Import or translate a book):
- Paste directly — Copy from your word processor and paste in. Best for editing a single chapter at a time.
- Upload a file — EPUB, Word, PDF, RTF, ODT, HTML, TXT or Markdown. Chapters split automatically from your headings.
- Import from a link — a book on Project Gutenberg, Standard Ebooks, Royal Road or ScribbleHub, or your own site.
- Open a project — If you wrote the book in Entangled Text, the chapters are already there.
Formatting that matters
The AI reads plain text and Markdown. Before pasting, strip out headers, footers, page numbers, and any layout-specific formatting. Keep paragraph breaks, italics (using asterisks), and scene breaks (three asterisks on a line). The cleaner the input, the fewer artifacts show up in the output.
Step 2: Write Effective Editing Instructions
This is where most people go wrong. The editing instruction is the single input that determines whether the AI produces something useful or something you immediately discard. Vague instructions get vague results. Specific, targeted instructions get surgical edits.
What bad instructions look like
Make it better.
Fix everything that's wrong with this chapter.
These tell the AI nothing about your intent. "Better" according to whom? "Wrong" by what standard? The AI will guess — and it will guess generically.
What good instructions look like
Effective editing instructions name the problem, describe the desired outcome, and stay focused on one dimension of the prose at a time.
Rewrite all dialogue in this chapter to feel more natural and conversational. Characters should use contractions, interrupt each other, and leave thoughts unfinished. Remove any dialogue where a character explains something they would both already know. Keep the same plot beats — only change how people talk.
This chapter drags in the middle. Cut or condense the three paragraphs where Maya walks through the market — keep one sensory detail and move on. Shorten the conversation with the vendor to four exchanges max. The chapter should feel like it's accelerating toward the final scene, not stalling.
The tone of this chapter is too detached. Add interiority: let the reader feel what Jonah is feeling through physical sensation and fragmented thought, not through narration. When he sees the letter, his hands should shake before he understands why. The dread should be in the body, not in the summary.
Strip every description in this chapter down to its strongest image. If a paragraph uses three metaphors, keep the best one and delete the rest. Replace any instance of "orbs" with "eyes." No similes longer than half a sentence. The prose should read lean and fast, not lush.
Step 3: Pick the Right Pass
There is no model to choose — editing runs on included Kestrel AI for your plan. The lever that actually changes the result is which pass you run. Each one targets a single dimension, so the edit stays predictable and easy to review.
- De-AI cleanup — Removes AI tells and unnatural phrasing. Start here when a chapter sounds robotic or hedged.
- Tighten & trim — Cuts filler, repeats, and lines that advance nothing. Best on an overwritten chapter; it will shorten the text.
- Voice & style and Emotion & interiority — The voice-sensitive passes. Use these when the prose is technically fine but flat.
- Dialogue, POV & clarity, Pacing & tension, Scene & sensory — Targeted fixes for one craft problem at a time.
- Line edit — Sentence-level cleanup: weak adverbs, passive voice, clichés, hedging.
Step 4: Review the Diff
After the AI processes your instruction, you don't get a mystery rewrite — you get a word-level diff that shows exactly what changed. This is where the editor becomes powerful: you can see every insertion, deletion, and substitution before you commit to anything.
How to read the diff
- Added — words or phrases the AI inserted that weren't in your original.
- Removed (struck through) — words or phrases from your original that the AI took out.
- Unchanged text — Everything the AI left alone. This is usually the majority of the chapter if your instruction was focused.
Read it like a track-changes document — card by card, or switch to the full-text view to read the chapter through. Where the AI deleted something you liked, drop that card. Also watch for additions that shift meaning in ways you didn't intend.
Step 5: Accept, Reject, or Re-Edit
The review shows one card per changed paragraph, before and after side by side. For each one:
- Keep — leave its switch on, and Accept applies it.
- Drop — switch it off and your original paragraph stays.
- Re-edit — neither version is right. Select the passage, adjust the instruction, and run it again on just that section.
When to accept
Accept when the AI's version is clearly better: tighter pacing, more natural dialogue, a stronger image replacing a weak one. If you hesitate, read both versions aloud. The one that sounds right when spoken is usually the right choice.
When to reject
Reject when the AI has flattened something distinctive — a quirky sentence you liked, a deliberate rhythm, an unusual word choice that carries meaning. Also reject when the AI over-corrects: shortening a passage that needed its length for emotional weight, or smoothing out a character voice that was intentionally rough.
Accepting everything
Every card starts kept, so if the whole pass is good, Accept applies all of it. Changed your mind afterwards? Ctrl/Cmd+Z takes the AI edit back.
Step 6: Export or Publish
Once your chapters are edited and you're happy with the text, you have several paths forward:
- Keep working — the book stays in Story Studio for more passes, beta readers, or a new edition.
- EPUB — a formatted ebook for Amazon KDP, Apple Books, Kobo, or any distributor, with chapter breaks, a table of contents, and your metadata. The KDP package bundles the upload files.
- DOCX or PDF — for editors, agents, beta readers, or layout tools like Vellum and Atticus.
- TXT or Markdown — plain text, as a backup or for other tools.
Your work is yours. Exports use open formats with no lock-in. Free-plan Word, PDF, Markdown and text files include a short Entangled Text foreword and afterword (not a watermark); the Kindle EPUB and the KDP zip carry one line on the copyright page. Pro and Ultra omit those attribution pages from exported files. Compare plans.
Tips for Better Results
Use multiple focused passes
The best editing workflow isn't one pass that tries to fix everything — it's three or four passes that each focus on one thing. Run a dialogue pass first. Then a pacing pass. Then a line-level polish pass. Each pass builds on the last, and the cumulative result is far better than any single all-purpose edit.
Keep instructions under control
If your editing instruction is longer than a paragraph, it's probably trying to do too much. Split it into two separate passes. The AI handles one clear objective better than five competing ones.
Ask for a list before a rewrite
Before substantive editing, ask Kestrel to flag inconsistencies, continuity errors, or repeated phrases without rewriting anything. That gives you a map of what actually needs fixing. On Pro and Ultra, Check consistency does this across the whole book.
Do not rewrite anything. Read this chapter and list: (1) any continuity errors with previous chapters, (2) repeated words or phrases used more than twice, (3) paragraphs that could be cut without losing plot or character information. Return the list, not a rewrite.
Trust your ear over the AI's confidence
The AI will always produce a result. It will never say "actually, this paragraph is fine — leave it alone." That means some changes are improvements and some are lateral moves disguised as improvements. If your original version reads well when spoken aloud, keep it. The AI's edit isn't better just because it's different.
