Roast and proofread your entire manuscript with your own AI. Free, open-source, and built for books of any length.
Free download. Your AI provider may charge for a plan or API usage.
Inspect the complete public source on GitHub · Read what stays local and what an AI provider sees.
Install one or use both in the order professional editing usually happens: structure first, correctness second.
Maps the complete book before judging it, then reviews plot, character arcs, pacing, dialogue, POV, continuity, style, and reader experience.
Checks the full book for errors and cross-chapter consistency while keeping objective corrections separate from subjective style advice.
No GitHub experience is required. Pick the environment you actually use.
Move the folder somewhere you can keep it, then open a terminal inside it.
python install.py --target codex --scope project --skill all --project-dir "/path/to/My Novel"Put your manuscript in the project. Type /skills if you want to confirm both skills are visible.
Use $manuscript-roast to critique my complete manuscript at manuscript.docx.Open a terminal inside the extracted folder.
python install.py --target claude --scope project --skill all --project-dir "/path/to/My Novel"cd "/path/to/My Novel"
claude/manuscript-roast Critique my complete manuscript at manuscript.docx.Keep a numbered checklist so no chapter is skipped.
For critique, update the book map. For proofreading, update the style sheet.
Save every chapter report outside the chat and verify quoted evidence against your original.
Open docs/INSTALL-CHATGPT.md after extracting the pack.
The local script preserves your original, discovers chapters, creates stable chunks, and records a manifest. The agent first reads across the book to build context, then works through each chunk. Completed chunks are saved to disk, so an interrupted run resumes from the first unfinished item.
Source protectedThe original is copied into input/ and never edited.
Context maintainedA book map or style sheet carries decisions across chapters.
Progress savedstate.json tracks complete and pending chunks.
Claims checkedThe validator catches skipped chunks and mismatched quotes.
The release includes The Bell Below, a three-chapter manuscript written for testing. No client work is used.

DiagnosisMara's final choice invokes her father before that relationship has acquired enough scene weight. Seed a concrete memory, object, or costly belief earlier so the action reads as her choice rather than the plot selecting the dramatic lever.

The included Python scripts only prepare local chapters, keep progress, and verify quotations. They do not upload manuscripts or call EditRoast servers. A reproducible GitHub Actions check scans Python entry points and all three release ZIP packages for suspicious network imports, executable calls, private file paths and common credential patterns. This project-run check is not an external security certification.
Important distinction: once you ask Codex, Claude Code or another AI service to analyze text, that service may receive the passages it reads according to its own terms. Review its data and training policies before using confidential work.

Yes. All three ZIP downloads are free, require no account, and use the MIT open-source license. Codex, Claude Code, or another AI provider may require its own paid plan or API usage.
There is no hard-coded manuscript word cap. The workflow splits long books and resumes across sessions. A longer book still takes more model turns, time, and provider allowance.
No. The preparation and validation scripts run locally and make no EditRoast network request. The AI provider you use receives whatever text its agent reads; check that provider's privacy and retention settings.
No. Version 1 produces an auditable Markdown correction report. It does not silently change the source or claim to preserve complex DOCX structure and tracked changes.
TXT, Markdown, and ordinary DOCX. EPUB is deliberately deferred in v1 to keep installation dependency-free and predictable.
Run the status command shown in the README. The workspace records every completed chunk and continues from the pending list.
These run in your browser and are separate from the downloadable Agent Skills.
The inspiration for EditRoast came from author Nadi Petrova's experience preparing and publishing her books. These open skills are free tools for authors who want to examine their own manuscripts before deciding on the next step.
