Prosed

Prosed is a service that transforms a creator's existing written and spoken content—newsletters, podcast episodes, blog posts, transcripts, and notes—into a structured, publish-ready manuscript. Users provide sources (Substack, YouTube, podcast links, transcripts, or files); Prosed's pipeline (The Inkwell) assembles and fills short connective 'bridges' where needed, and the Typo reviewer evaluates grammar, voice, flow, and cohesion. Creators work in a private portal to review chapters, request rewrites, and export the final manuscript as PDF, ePub, or DOCX. Prosed emphasizes author ownership (you own 100% of your book), transparency (a Source Map that shows which words are original vs. added connective tissue), and a fast turnaround during its beta offering.

Key Features

Content ingestion & transcription

Paste Substack, YouTube, or podcast links, or upload transcripts and notes; Prosed pulls and transcribes spoken content to gather source material.

The Inkwell assembly pipeline

A multi-stage pipeline built on patterns from 150+ bestselling nonfiction books that structures content into a complete manuscript and writes short connective bridges where ideas need linking.

Typo editorial reviewer

An editorial reviewer that checks grammar, voice, flow, and cohesion; every note links to the exact passage in the manuscript.

Private editorial portal

A distraction-free reader where users can read chapters, leave comments, accept or reject suggestions, and request revisions.

Source Map transparency

A view that color-codes paragraphs to show which words are the creator's and which are connective tissue added by Prosed, with ratios (e.g., 90%+ creator words).

Export and publish

Export finished manuscripts as print-ready PDF, ePub, or DOCX for publishing or selling (including on Amazon).

Ownership and data controls

Users retain 100% ownership of their book; the site states content never trains models, is never shared, and is deleted on request.

Included rewrites and ongoing edits

Beta includes five full rewrites per book; Typo feedback and chapter-level edits remain unlimited; additional rewrites available for a fee.

Benefits

Quick assembly of a manuscript from existing content, often in days rather than months.
Editorial infrastructure (pipeline + Typo reviewer) that aims to maintain the creator's voice across chapters.
Transparent provenance via the Source Map so creators can see which words are theirs versus added connective tissue.
Lower cost compared with traditional ghostwriting (beta pricing $47 vs. ghostwriter estimates cited on the page).
Export-ready outputs (PDF, ePub, DOCX) and full ownership retained by the creator.

Limitations

Currently focused on non-fiction; fiction is on the roadmap.
Requires existing source material (newsletters, posts, episodes, or transcripts); Prosed will notify you if there isn't enough to make a book.
Beta pricing and availability are limited (first 100 books at $47).

Frequently Asked Questions

Is this for non-fiction, fiction, or both?
Non-fiction for now: self-help, memoir, business, and essays. Fiction is on the roadmap.
Do I need existing material?
Yes. Prosed pulls from Substack, YouTube, podcast, or files. If there isn't enough to make a book, they'll tell you before you pay.
What do I actually get?
A complete first-draft manuscript in your private portal. Read, comment, revise, then export as PDF, ePub, or DOCX.
Will it actually sound like me?
Yes — Prosed assembles your existing sentences and the Source Map shows which words are yours; the page states over 90% of every book is the creator's own words.
Is this just AI writing my book?
No. Prosed assembles your existing words and marks every bridge it adds; the service describes itself as an editorial pipeline rather than purely AI output.
Who owns the book?
You do. The page states you own 100% of your book, content never trains models, is never shared, and is deleted on request.
