Use tool ↗About Prosed
Prosed turns a creator's existing body of work into a non-fiction book manuscript instead of generating new text. It runs as an MCP connector: you paste one address into ChatGPT, Claude, Cursor or another assistant, pull in a Substack, blog, YouTube or podcast archive, and shape the chapter outline in conversation. Its pipeline then assembles chapters from your own sentences, marks the bridging lines it wrote in a source map, and an editorial reviewer comments on grammar, voice and flow before you export PDF and DOCX. Fiction is not supported yet.

Pros & cons of Prosed
Prosed is for people who already have years of newsletters, episodes or posts and want them assembled into a book in their own words, not a fresh AI draft. The free outline step is an honest test of whether the archive holds a book, and $49 per book is small next to a ghostwriter; writers starting from an idea, or writing fiction, get nothing here.
Pros
- Loading the archive and seeing the outline cost nothing, so you learn whether there is a book before paying
- Flat $49 per book with no subscription
- A source map shows which lines are yours and which are bridges it wrote
- Works inside several MCP-capable assistants and exports PDF and DOCX
Cons
- Still a private beta according to its own terms, from a small team
- Non-fiction only
- Needs an assistant that supports custom MCP connectors
- Delivers a first-draft manuscript; editing, design and publishing remain your job
Best for
- Newsletter writers, podcasters and coaches sitting on large archives
- Creators who want a first manuscript in their own voice to take to an editor or self-publishing
- People already working in ChatGPT or Claude who would rather add a connector than learn another app
Not for
- Fiction writers, since only non-fiction is supported for now
- Anyone without a body of existing material to assemble
Watch out: The terms name no legal entity or country and put disputes under 'the jurisdiction in which Prosed operates', so there is little to go on if a paid project goes wrong; each extra book is another $49.
