Prosed
Prosed turns existing content from newsletters, posts, podcasts, videos, notes, and transcripts into a publish-ready non-fiction manuscript. It is built for creators and aspiring authors who want guided drafting, editorial review, and exportable book files.
Turn existing content into a book
Prosed is a book-creation service for creators and aspiring authors who already have substantial material in newsletters, posts, podcasts, videos, notes, or transcripts. Its goal is to turn that existing work into a publish-ready non-fiction manuscript without starting from a blank page.
The workflow combines a creative brief, content ingestion, manuscript assembly through The Inkwell, chapter-level review in a private portal, and editorial checks from Typo. The site positions the product as a publishing process rather than a simple AI writing tool, with exports available as DOCX, PDF, and ePub.
What Prosed does
Assemble a manuscript from existing writing
The Inkwell restructures your existing material into a complete non-fiction manuscript using a multi-stage pipeline built around patterns from bestselling books.
Review chapters in a private portal
Read each chapter in a private portal, leave comments, accept or reject suggestions, and request rewrites without leaving the workflow.
Editorial review with passage-level notes
Typo reviews voice, grammar, story flow, chapter cohesion, and brand alignment, with each note linked to the relevant passage.
Export publish-ready files
Export the finished book as a print-ready PDF, ePub, or DOCX for publishing or direct sale.
Capture a detailed creative brief
The creative brief asks for content, topic, audience, tone, structure, and design preferences so the draft can reflect the author’s voice and intent.
Common ways to use Prosed
Turn a publishing archive into a book
Convert a Substack archive, blog, or newsletter back catalog into a single manuscript that organizes the strongest ideas into a book-length structure.
Repurpose spoken material
Upload transcripts, notes, or recordings from talks, podcasts, or videos and use them as the source for a written manuscript in the same voice.
Develop a book from a rough concept
Use the creative brief to define audience, tone, structure, chapter length, and personal-story balance when you have an idea but need help shaping it into a book.
Edit the draft collaboratively
Review chapters in the portal, comment on sections, and request rewrites when you want iterative control over the draft before export.
Prepare files for publishing
Export DOCX, PDF, or ePub files when you want a manuscript you can self-publish, share with readers, or continue refining elsewhere.
