Prosed

The Inkwell is the multi-stage engine underneath Prosed, built from patterns the team observed across 150-plus bestselling nonfiction books. It edits, restructures, and writes the connective tissue that turns separate posts into chapters. The important detail is where those connecting sentences come from. The pipeline writes a bridge between two of your ideas when one is needed, and it always flags the spot. You see the seams instead of being told there aren't any.

Typo acts as a dedicated manuscript editor and AI editor rather than a spell-checker. It looks at grammar, voice, flow, and cohesion across a chapter, and every note it leaves links to the exact passage it refers to. That link matters more than it sounds. Vague feedback like "tighten this section" is useless in a 300-page draft. Typo pins its suggestions to real text, so you can act on them.

Every chapter gets a distraction-free reader inside your private portal. From there you comment, accept or reject Typo's suggestions, and request revisions chapter by chapter. Working one chapter at a time keeps the editing job small enough to actually finish, which is the part most book projects fall apart on. That's the whole point.

Prosed runs through MCP, so it lives inside ChatGPT, Claude, Cursor, or any other assistant that supports the protocol. You paste one address, sign in once, and then load archives, ask questions, and shape outlines without leaving the conversation. For people who already write in these tools, the setup is closer to enabling a feature than adopting new software.

You point Prosed at a Substack, a blog, a podcast, or a set of transcripts and notes, and it reads everything rather than a sample. In one example on the company's site, loading a Substack returned 148 posts and 214,000 words going back to 2019. That thoroughness makes the "is there a book in here" question answerable instead of a guess.

You tell Prosed how you talk, which phrases you love, and which ones you never want to see again. Those instructions hold across the manuscript, so a hated word stays out and a signature phrase lands where it belongs. Every sentence in the finished book comes from your own writing, and the source map shows which lines are yours and where the pipeline bridged between them.

When a draft is ready, you take it away as a PDF and a DOCX. The DOCX matters if you plan to keep editing in a word processor or hand the file to a traditional editor, and the PDF gives you a clean version to read start to finish. Read it, revise it as often as you like, then export again. No lock-in either.
