    Review History

    Review Studio Guide

    Everything you need to run a professional manuscript review from upload to finished corrected draft.

    What This App Does

    Manuscript Review Studio runs your manuscript through a structured seven-stage editorial process using three simultaneous expert perspectives: a professional book editor, a book marketer, and a subject matter expert for your specific domain. The review is unsparing — it provides the level of critique a serious publisher's editorial team would deliver before committing to print.

    The Six Stages

    1 — Manuscript Input

    Upload your manuscript as one or more files. Reorder multi-file uploads to set chapter sequence. The app assembles everything into a single text before review begins.

    2 — Pre-Review

    Before the full review, the app derives five key points from the manuscript itself: author positioning, subject matter domain, target reader profile, competing titles, and a front/back matter audit. You confirm these before proceeding.

    3 — Critical Review

    A complete six-section analysis covering structural integrity, voice and pacing, prose quality, factual accuracy, front/back matter, and market positioning. No section is omitted. No findings are softened.

    4 — Recommendations

    One best recommendation per issue identified in the Critical Review — written and ready to implement. No option lists. Decisive, actionable guidance with a brief justification and one viable alternative per recommendation.

    5 — Title Evaluation

    Evaluation of title, subtitle, and author name as a trio. Covers genre fit, Amazon discoverability, and series branding. Includes pen name recommendation if no author name was found, or evaluation of the existing name's market fit.

    6 — Cover Design

    Generates a scroll-stopping ChatGPT prompt for your book cover. Ebook: front cover prompt. Print/Both: full cover dimensions, editable back cover blurb, author bio, and complete print cover prompt. Upload 3–4 ChatGPT versions and Claude recommends the strongest.

    7 — Implementation

    A single corrected manuscript pass incorporating the confirmed title, subtitle, and author name, plus all accepted recommendations. Download as .md, .txt, or .pdf. Followed by AI-generated rule recommendations to personalize future reviews.

    The Rules System

    Rules are custom editing and formatting instructions that apply to every review you run. They are appended to the review instructions automatically. Over time, your Rules library becomes a personalized style guide that shapes every manuscript the app touches.

    See the Step-by-Step tab for full details on creating and managing rules.

    Before You Start

    Open Settings (⚙ top right) and enter your Anthropic API key. Click Test Connection to confirm it works. Your key is stored only in your browser — it is never sent anywhere except directly to Anthropic's API.

    💡 Tip: If you don't have an API key, visit console.anthropic.com to create one. You'll need a funded account — reviews consume a moderate number of tokens per session.

    Step 1 — Upload Your Manuscript

    Click the upload area or drag files onto it. You can upload:

    • .md or .txt — plain text, read directly
    • .docx — Word documents, text extracted automatically
    • .pdf — text extracted from each page
    • Multiple files — e.g., one file per chapter

    If you upload multiple files, a reorderable list appears. Drag files into chapter order before proceeding — this is the order they'll be assembled and reviewed.

    Large manuscripts: The app will warn you if your manuscript exceeds approximately 80,000 words. Very large files may approach the AI's context limit. If this happens mid-review, the app will attempt automatic recovery and provide manual recovery steps if needed.

    Step 2 — Pre-Review Confirmation

    After assembly, the app automatically runs a Pre-Review analysis and streams the results into the transcript. Review the five derived points:

    1. Author positioning
    2. Subject matter domain
    3. Target reader profile
    4. Competing titles
    5. Front/back matter audit

    If anything looks wrong, use the text input at the bottom to add a correction before confirming. When satisfied, click Confirm — Begin Critical Review.

    Step 3 — Critical Review

    The longest phase. Six sections stream into the transcript one by one. You can add notes or questions in the text input at any point — the reviewer will incorporate them. When the full review is complete, click Confirm — Begin Recommendations.

    Step 4 — Recommendations

    Each issue from the Critical Review receives one best recommendation — formatted as: recommendation → brief justification → one viable alternative. Review carefully. Use the text input to push back, ask for elaboration, or accept with notes. When done, click Confirm — Begin Title Evaluation.

    Step 5 — Title Evaluation

    Title, subtitle, and author name are evaluated as a trio. If Phase 1 found no author name in the manuscript, this phase opens with that flag. The reviewer will:

    • Recommend one title and subtitle with justification and one alternative
    • Confirm or recommend an author name / pen name with justification and one alternative
    • Consider genre fit, Amazon searchability, and series branding

    Confirm your choices in the text input, then click Confirm — Begin Implementation.

    Step 6 — Implementation

    The app produces a single corrected manuscript incorporating your confirmed title, subtitle, author name, and all accepted recommendations. When complete, three download buttons appear — see the Export & Production tab for what to do next.

    Using the Rules System

    Before Starting a Review

    Open the Rules tab and confirm all rules are correct and enabled before clicking Begin Review. Rule changes made during a review do not take effect until the next review. If you want a rule change applied to the current manuscript, you must restart the review from the beginning.

    Four Ways to Create Rules

    1. Rules tab → + New Rule — write directly, any time.
    2. 💾 Save as Rule button on any Claude response in the transcript.
    3. + Suggest Rule button in the input bar during a review — queues your suggestion for post-review evaluation. Does not affect the current review.
    4. Post-Implementation rule recommendations — AI-generated, reviewed one-by-one with dialogue before being added.

    Suggesting Rules Mid-Review

    If you notice a pattern worth capturing while the review is in progress, click + Suggest Rule in the bottom input bar. Enter a short title and description. Your suggestion is saved but not applied to the current review — it will be surfaced during the post-review rule evaluation, where Claude assesses it, recommends refined wording if needed, and you discuss it before it is added.

    Post-Review Rule Dialogue

    At the end of every Implementation, the app presents all candidate rules — app-generated and your suggestions — one at a time. For each you can: Accept to add it immediately, Discuss to open an inline dialogue with Claude to refine the wording, or Skip to discard it. User-suggested rules are automatically evaluated by Claude first, with refined wording recommended where appropriate.

    Enabling and Disabling Rules

    Each rule has a toggle switch. Disable a rule temporarily without deleting it — useful if a rule applies to one series but not another. Only enabled rules are sent to the reviewer.

    💡 Best practice: After your first full review, open the Rules tab and formalize any patterns you found yourself repeatedly correcting. These become your personal house style guide.

    Session Recovery

    Your session — including the transcript, current phase, and assembled manuscript — is automatically saved to your browser's local storage after each phase. If you accidentally close the browser, reopen the app and you'll be prompted to resume where you left off.

    If the AI hits a context limit mid-review, the app will:

    1. Pause and explain what happened in plain language
    2. Attempt automatic recovery (compressing prior context and continuing)
    3. If automatic recovery fails, display a manual recovery panel with step-by-step instructions and a Restart from Phase X button

    Downloading Your Manuscript

    At the end of Phase 6 (Implementation), three download buttons appear in the transcript:

    • Download .md — Recommended. Markdown format, best for Pandoc → EPUB or PDF production.
    • Download .txt — Plain text fallback, universally compatible.
    • Download .pdf — In-browser PDF generated instantly, good for quick sharing or archiving. Not suitable for professional print interiors.
    💡 Recommendation: Download .md as your primary file. Use Pandoc (free) to convert it to EPUB for KDP or PDF for distribution.

    Installing Pandoc

    Pandoc is a free, open-source tool that converts between document formats. It runs from the command line.

    Mac

    If you have Homebrew installed:

    brew install pandoc

    If you don't have Homebrew, download the installer from pandoc.org/installing.html

    Windows

    Download the .msi installer from pandoc.org/installing.html and run it. Pandoc will be available in Command Prompt after installation.

    Linux

    sudo apt install pandoc
    💡 After installing, verify it worked by opening a terminal and typing pandoc --version. You should see a version number.

    Creating an EPUB File

    EPUB is the format Amazon KDP accepts for Kindle ebooks. Here's how to convert your downloaded .md file:

    Step 1 — Open your terminal

    Mac: Open the Terminal app (search Spotlight for "Terminal").
    Windows: Open Command Prompt (search Start for "cmd").

    Step 2 — Navigate to your manuscript folder

    Use the cd command to go to the folder where you saved your .md file. Replace the example path with your actual folder location:

    # Mac / Linux example: cd Desktop/manuscripts # Windows example (same command): cd Desktop\manuscripts
    💡 What is cd? It stands for "change directory" — it moves your terminal into that folder, so the next command knows where to find your file.

    Step 3 — Run the conversion

    pandoc input.md -o output.epub

    Replace input.md with your actual filename and output.epub with whatever you want the EPUB file named. The EPUB will appear in the same folder.

    KDP note: Pandoc generates a valid EPUB 3 file that KDP accepts. KDP will auto-generate a table of contents from your headings. Review the KDP file requirements at kdp.amazon.com before uploading.

    Creating a PDF File with Pandoc

    Pandoc can produce high-quality PDFs, but requires a LaTeX engine to be installed. The easiest free option is TinyTeX.

    Step 1 — Install TinyTeX

    Mac / Linux:

    curl -sL "https://yihui.org/tinytex/install-unx.sh" | sh

    Windows: Download and run the TinyTeX installer from yihui.org/tinytex

    Step 2 — Navigate to your manuscript folder

    cd Desktop/manuscripts

    Step 3 — Run the conversion

    pandoc input.md -o output.pdf

    Replace input.md and output.pdf with your actual filenames.

    💡 In-browser PDF vs. Pandoc PDF: The in-browser PDF download (from the app) is instant and good for sharing or archiving. The Pandoc PDF uses proper typesetting and is suitable for professional distribution or print review copies.

    Editing Rules

    Good time to review your rules. Confirm all rules below are correct and enabled before starting your manuscript review. Changes here will be applied from the beginning of your next review.

    Rules are custom editing and formatting instructions applied to every review automatically. Toggle rules on or off without deleting them. Active rules are appended to the review instructions on every API call.

    No rules yet. Add your first rule above, or save one from the transcript during a review.

    Settings

    Enter your Anthropic API key below. It is stored only in your browser's local storage and sent exclusively to Anthropic's API.

    🔒 Your API key never passes through any third-party server. It travels directly from your browser to api.anthropic.com.

    Suggest a Rule

    Describe an editing or formatting rule you'd like applied to future reviews.

    📌 Your suggestion will not be applied to the current review in progress. It will be surfaced during the post-review rule evaluation at the end, where you and Claude can refine it before it's added to your Rules library.

    Save as Rule

    Give this rule a short title and edit the description so it reads as a clear instruction for future reviews.
