Penmark Studio does not grade your grammar and it does not write your book. It reads the manuscript you wrote and tells you, in editorial language, what to fix and in what order.
“I don't know if the book works.”
A full-manuscript structural read: premise, structure, arc, stakes, sagging middles and unearned endings, judged against published standards in your genre and comparable titles. Returns a ranked list of the structural problems worth fixing before anything else.
“This chapter feels off and I can't say why.”
Pacing, voice and line quality on a single chapter, with the specific passages quoted back to you and recommendations ordered by impact — not a list of everything that could conceivably change.
“I've rewritten this so many times I've lost the thread.”
Character details, settings and timeline checked across any chapters you select. Every inconsistency is flagged with where it breaks and what the fix is.
“Chapter 1 and Chapter 20 don't sound like the same book.”
Finds where your voice drifts between chapters — register, distance, sentence rhythm — and tells you which passages to bring back in line. It protects your voice; it never substitutes its own.
“It's too long and every sentence feels precious.”
Word-level precision on one chapter: cut candidates, dead adverbs, rhythm notes and places where two sentences are doing one sentence's work.
“Will a reader actually keep going?”
A read-through in the shoes of your target reader, reporting where attention drops, where it spikes, and which page a browsing reader is most likely to put the book down on.
Every review produces discrete action items. Mark each one resolved as you revise, and Penmark records which version of the chapter resolved it. You always know what is still outstanding.
Every save is preserved. Compare where a chapter was before the edit and after it, and roll back when a revision made things worse.
Open feedback, chapters that still need work and progress over the week — in one view, so a long revision stops feeling like a shapeless pile.
Hide the interface and read the book as a book. Export the full manuscript as .docx or .md, chapters as .md, reports as .md or .pdf, and your entire account as a ZIP.
