How It Works

Two workflows, one project. Edit a finished manuscript through four professional stages, or write new chapters with Assist — the AI learns your voice before it suggests a word. Both use the same models trusted by leading publishers.

Writing New Chapters with Assist

Assist helps you plan and draft the chapters you haven't written yet — but you're the author at every step. Assist proposes, you decide, you edit, you repeat. It reads your existing manuscript, learns your voice, and generates chapter drafts into a staging area — nothing touches your manuscript until you review and accept it. Expect to iterate: regenerate plans if none fit, discard drafts that miss the mark, re-score your own edits, and keep going until a chapter feels right. The four-step loop below is designed to go around more than once.

1. Plan

The Forward Planner reads your Story Brain (characters, open threads, beats) and proposes three distinct directions for the next chapter. You pick the one that matches your vision — or, if none of them do, regenerate with a sharper "direction" note. Options are cheap. Once you pick, the planner breaks your choice into a scene-by-scene beat plan you can tweak before drafting.

Model: Sonnet 4.6 Output: Beat plan

2. Draft

The style enforcer writes the chapter from your beat plan, scores each pass against your voice fingerprint, and rewrites up to three times trying to hit an 80% match. You watch live progress ("Iteration 2 — 74% style match") and can safely leave the page — the draft keeps writing in the background. Typical time: 1-3 minutes. If the draft's direction doesn't feel right when you read it, there's no commitment at this stage — discard and run again with a different plan or tighter guidance.

Model: Opus 4.6 Output: Draft in your voice

3. Review in Staging

Drafts land in Staging, not your manuscript — this is where the creative back-and-forth actually happens. Read the draft, edit in place to shape the prose, re-score your edits to see how your changes moved the voice match, and iterate until a version feels right. Discard-and-retry is a normal tool here, not a failure mode. Each card shows whether the AI's draft hit the voice target (green "Voice target met") or not (yellow "Best of 3 attempts"), so you know how much shaping it likely needs going in.

Author-driven (no AI call) Output: Reviewed draft

4. Accept into manuscript

Accept inserts the draft (with your edits baked in) at the right position in your book and records a provenance entry so AI-assisted passages are excluded from future style-fingerprint extractions. Your fingerprint keeps reflecting your writing, not the AI's. From there, loop back to step 1 for the next chapter — the manuscript grows from your decisions, one chapter at a time.

The Editing Pipeline

When your manuscript is done — whether you drafted it with Assist, wrote it in Word, or pasted it in — the editing pipeline takes it through up to four professional editing stages. Each stage targets a different layer of your writing. Run all four, or toggle individual stages on and off.

Running the pipeline

Step 1

Upload

Drop in your manuscript as .docx, .txt, or .md. Chapters are detected automatically — no special formatting required.

Step 2

Configure

Choose which editing stages to run. See cost and time estimates upfront. Toggle stages on or off — run the full pipeline or just what you need.

Step 3

Download

Watch progress in real time. When it's done, download your edited manuscript and per-stage outputs. Re-run anytime.

The four stages

1. Pre-Edit Assessment

A diagnostic pass that reads every chapter and produces a detailed quality report — no rewrites. Flags structural issues, pacing problems, and areas that need attention. Think of it as your editor's first read-through notes.

Model: Sonnet 4.5 Output: Assessment report

2. Developmental Edit

The big-picture edit. Rewrites for structure, pacing, character arcs, plot consistency, and narrative tension. Chapters are processed in batches so the AI can hold context across scenes.

Model: Opus 4.6 Output: Rewritten manuscript

3. Line Edit

Sentence-level refinement. Sharpens voice, fixes dialogue rhythm, eliminates AI-tells and cliches, and tightens prose. Uses custom rules to catch the patterns that make AI-assisted writing feel generic.

Model: Opus 4.6 Output: Polished manuscript

4. Copy Edit

The final polish. Catches grammar, spelling, punctuation, and consistency errors. Ensures character names, places, and details stay consistent across chapters.

Model: Sonnet 4.5 Output: Clean manuscript

Using Assist and the Pipeline Together

Most authors who use both features do so in that order: Assist first while the book is being written, then the editing pipeline once the manuscript is complete. Here's what that looks like inside one project.

A

While you're still writing, use Assist

Extract your style fingerprint once, run the Story Brain analysis, and use the Forward Planner + chapter drafter to write new chapters over days, weeks, or months. Each accepted draft is recorded with provenance so your fingerprint stays honest. Re-run the Brain analysis occasionally as the manuscript grows.

B

When the manuscript is complete, run the editing pipeline

From the same project, switch to the editing side. Run the pipeline on the finished manuscript. The four stages don't know or care which passages were Assist-drafted and which you wrote from scratch — they edit the whole book for structure, pacing, sentence-level prose, and final polish.

C

Want to mix order? You can.

Nothing forces a strict sequence. You can run a pre-edit assessment on an early draft to diagnose structural issues, go back to Assist to rework specific chapters, then run the full pipeline later. Both workflows share the same manuscript under the hood.

Time & Cost

Estimates are shown before you run. You only pay for the AI API calls — we don't mark them up.

Manuscript Size Time (all 4 stages) Estimated Cost
Short novel (30K words) ~8 min ~$5
Standard novel (50K words) ~14 min ~$8
Full novel (80K words) ~22 min ~$13
Epic (120K+ words) ~35 min ~$19

Cost estimates are based on real-world edit data and Anthropic direct pricing (BYOK). Actual costs vary by manuscript complexity and caching. Running fewer stages reduces both time and cost proportionally.

Your Manuscript Is Safe

Your API key, your account

BYOK (Bring Your Own Key) means your manuscript goes directly to your Anthropic or OpenRouter account. We never see your API traffic.

No training on your work

Anthropic's API does not use your data for model training. Your unpublished manuscript stays unpublished.

Encrypted key storage

API keys are encrypted at rest. Session tokens are signed. No plaintext secrets stored.

Delete anytime

Your projects and manuscripts can be deleted from the dashboard. When you delete a project, all files are removed from the server.

Frequently Asked Questions

How is Cherry Edits different from ChatGPT, Claude, or Sudowrite?
Chat tools produce prose in a generic model voice and leave it up to you to notice when the AI head-hops, drifts tense, or leans on AI-telltale rhythms. Cherry Edits measures your actual writing across 19 style dimensions, detects your POV mode and tense, and checks every AI draft against both before you see it. Drafts below an 80% voice match, or with fatal POV violations, get rewritten — up to three times — before reaching your staging area. You also get two complete workflows in one project: the four-stage Edit pipeline for a finished manuscript, and Assist for planning and drafting new chapters.
What happens to my manuscript — do you store it or train on it?
Your manuscript is stored in a per-project volume scoped to your account and is never used to train any model, by us or by your AI provider. With BYOK, your text goes from our app directly to your own Anthropic or OpenRouter account over an encrypted connection — we don't mirror it to a third-party cache or markup layer. You can export your files and delete your project at any time.
What's the difference between "Edit" and "Assist" — do I need both?
Edit runs a finished manuscript through up to four professional stages — developmental, line, copy, and proofreading. Assist helps you plan and draft the chapters you haven't written yet, one chapter at a time, with your voice profile enforced. Most authors write with Assist chapter by chapter and then run the Edit pipeline on the completed draft. Either side works on its own — you're never required to use both.
How does Assist actually learn my voice?
Nothing is trained on your text. Assist measures your existing prose across 19 dimensions — sentence length distribution, paragraph rhythm, clause depth, punctuation signature, dialogue tag patterns, adverb and passive ratios, distinctive phrases, and your pet words, among others — and stores the result as your style fingerprint. Every AI draft is then scored against that fingerprint; drafts below 80% match trigger an automatic rewrite, up to three times. Your fingerprint is extracted once per project from the Assist dashboard.
How do you prevent the usual AI-slop problems (head-hopping, POV drift, "not X, not Y, not Z" rhythms)?
Two programmatic validators run on every draft before it reaches you. The style enforcer catches AI-tells at generation time — em-dash overuse, fragment-sentence cascades, rhetorical tricolons ("not X, not Y, not Z"), repetitive openers, and a banned-phrase list. The POV enforcer checks for head-hopping, tense drift, POV-mode mismatch, a first-person narrator's name appearing in their own narration, and motive attribution to non-POV characters. Fatal violations force a rewrite — they never reach your staging area.
What if my book has unusual POV or tense (second person, dual POV, present tense)?
Your Assist dashboard shows a Narrative Voice card with the detected POV mode, tense, POV character(s), and alternation pattern (single POV, alternating duet, rotating ensemble, scene-level switching, or free). If detection got any of it wrong, or you want to write against a different spec than what's in your existing prose, the Override button lets you set it manually — first, second, or third person; close or omniscient; past or present; single or multi-POV. Assist treats your setting as a hard constraint on every future draft.
What if the AI produces something I hate?
Nothing AI-generated lands in your manuscript automatically. Every draft goes to a staging area where you can review, edit it line by line, re-score your edits against your voice, and then accept or discard. Accepted drafts record a provenance entry so those passages are excluded from future voice-fingerprint extractions — your fingerprint keeps reflecting your writing, not the AI's. Discarded drafts leave no trace in your manuscript.
What does BYOK cost me compared to a managed service?
With BYOK (Bring Your Own Key) you pay Anthropic or OpenRouter directly at their published rates — we don't proxy, cache, or markup the API. For a typical novel you should expect a few dollars for a full Edit pipeline and pennies per Assist chapter. Caching across re-runs means subsequent passes are often cheaper than the first. If you'd rather not manage your own key, the Studio plan (coming soon) bundles managed API access into a single subscription.
What if a job crashes or I hit a rate limit?
Edit pipeline: progress is saved per chapter, so a re-run picks up where it left off and skips chapters that already completed — you're never charged twice for the same work. Assist: Brain analysis and draft generation persist state to the database, so if a job crashes or a rate limit trips you can retry from the dashboard without losing progress.
Can I work on a series, or on a manuscript I haven't finished yet?
Both. Series projects run a continuity analysis across all books first — extracting characters, timelines, world rules, and plot threads — and generate a series bible so each book is edited and drafted with full awareness of the others. Naming inconsistencies or other cross-book issues can be optionally resolved before editing. Partial manuscripts are supported in Assist — upload what you have, and Brain analysis marks the book as partial so the planner doesn't expect a resolved ending. Draft the next chapter from there.
