An expert editor on every page
Finally, technology that actually understands your story, your characters, and your intentions. Deep editorial feedback while you draft and during editing, built by writers and editors, trusted by thousands.
Write with an editor beside you.
The Manuscript Editor puts deep story understanding into your draft: chapter reviews, beta readers, and craft notes grounded in your whole novel. Coaching asks the hard questions when a scene stalls. A revision checklist keeps every note on track. We never write for you.
Finish a chapter and get clear feedback on what is landing and what still needs work. We already know where you are in the story, where you are headed, who is who, and what each beat means.
A full developmental edit.
When the draft is ready, get a whole-book read that maps structure, character, pacing, and craft. The reports authors trust, grounded in deep story understanding of your novel.
The synthesis report. It collates the underlying craft analyses, builds a roadmap, and delivers the most impactful feedback for your goals, genre, and audience. The compilation work authors often pay thousands for a human developmental editor to do.
Marketing.
Start with a deep read of today's market for your genre, audience, and comps. Then generate draft pitch materials from your manuscript and edit them until they are yours.
An in-depth view of the current market: trends, comps, audience expectations, and where your manuscript fits. Included with First Edition and Masterpiece, and it informs how your pitch materials take shape.
It understands your story. It never rewrites it.
Story Stream builds a story graph of your novel, runs specialized craft experts shaped by editorial wisdom, and treats cultural care and your voice as non-negotiable. Your manuscript is never used to train models.
A story graph of your novel
We build a living map of characters, locations, events, themes, and the relationships between them, chapter by chapter. Feedback is grounded in that graph, so notes know who is who and what each beat means. That is why feedback feels native to your story, not generic.
Editorial wisdom, specialized experts
A mixture of specialized craft experts (plot, pacing, character, theme, and more), shaped with editors around more than 500 craft elements. Guidance follows how a real fiction editor thinks, not a single generic opinion.
Built to catch bias
Cultural Analysis and diverse beta readers look for subtle bias, stereotypes, othering, and unexamined defaults, so representation stays nuanced, authentic, and respectful of the readers who will meet your work.
Trusted by thousands of authors
I was stunned by the depth of the report. It will hugely improve the quality of my novel.

Convent Inception, Historical Fantasy
Story Stream took my novel and pinpointed every issue—and every strength.
David Boevers
Where the Morning Star Fell, Dystopian Sci-Fi
The feedback from Story Stream was very detailed and informative.
Rebecca Schmuck
Tattered, Psychological Thriller
The pacing tool was pretty spot on—it shows you which parts of your story might be moving too slowly or too quickly, and gives ideas on how to fix them.
Sadie Bosque
Gone with the Rake, Historical Romance
I'd highly recommend this software to any writer serious about improving their work.

Where the Morning Star Fell, Dystopian Sci-Fi
Not only does Story Stream find the weak spots (info dumps, lagging dialogue, etc.) it gives the author ideas for how to fix them.

Shades of Gray Trilogy, Historical Fiction
It's a total game-changer!

Shades of Gray Trilogy, Historical Fiction
I was blown away. I have spent thousands of dollars on editors that gave me nowhere near the detailed feedback.
