StoryWith AI is a decision-support studio for novelists and non-fiction authors. Upload your manuscript and it runs a full developmental analysis โ structure, character arc, dialogue, continuity, readability, pacing, and theme โ and gathers synthesized reader feedback, then turns everything into a prioritized, actionable revision plan.
Unlike generative AI co-writers, StoryWith AI is assistive, never generative: it helps you improve the book you actually wrote instead of writing it for you, so your voice โ and your rights โ stay yours.
What it does - AI manuscript analysis across structure, arc, dialogue, continuity, readability, and theme - Plot-hole and continuity checking - An AI beta reader that synthesizes reader feedback - A story bible for characters, timelines, and world details - A prioritized list of what to fix next - A pitch / submission kit for querying agents and publishers
Available on web, iOS, and Android in 10 languages. A free plan is available; paid tiers start at $19/month. A focused alternative to tools like Marlowe, ProWritingAid, AutoCrit, and Fictionary for authors who want analysis and feedback rather than AI-generated prose.

StoryWith AI's answer:
StoryWith AI is assistive, never generative. Instead of writing your book for you, it reads the manuscript you already wrote and runs a full developmental analysis โ structure, character arc, dialogue, continuity, readability, and theme โ plus synthesized reader feedback, then hands you a prioritized revision plan of what to fix next. Your voice and your rights stay yours.
StoryWith AI's answer:
StoryWith AI grew out of a simple frustration: every new AI writing tool wanted to write the book for the author. But serious writers don't want their voice replaced โ they want to understand what's working and what isn't, and know what to fix next. StoryWith was built to help authors see their story "as a system": draft it, diagnose it across structure, arc, dialogue, continuity, readability and theme, gather real reader feedback, and get a prioritized revision plan โ all while keeping full ownership of their words.
StoryWith AI's answer:
Most AI writing tools sit at the extremes: generative co-writers (e.g. Sudowrite) write prose for you, while line editors (e.g. ProWritingAid) focus on grammar and style. StoryWith owns the developmental middle โ it tells you what to fix in the story and in what order, combining structure, arc, dialogue, continuity, readability and theme analysis with synthesized reader feedback into one ranked action plan. And it never rewrites your words: assistive, never generative.
StoryWith AI's answer:
Novelists and non-fiction authors who already have a draft and want to make it better โ writers preparing a manuscript for revision, beta reading, or submission to agents and publishers. It's built for people who want analysis and honest feedback on the book they wrote, not AI-generated text. Fiction and non-fiction, from first-time authors to experienced self-publishers, in 10 languages.
Let me look at the real numbers on this one. Book two of my series meant every thread I left open in book one was now a promise, and I had eleven of them with four in conflict. Two weekends of moving sticky notes got me nowhere. The continuity pass tracks what the manuscript asserts and who knows what, then names the exact two scenes that contradict each other. Three of my four conflicts turned out to be information problems, not plot problems. The fourth was real and I cut a subplot.
This is the first tool that fit how I actually write, which is in twenty five minute pockets. The diagnostics and continuity checks tell me what my draft needs, the action list tells me where to start, and it never tries to write the prose for me. Free to try, so you can see if it fits your pockets too
StoryWith AI is an impressive platform for authors who want practical support throughout the writing process. Its manuscript diagnostics, continuity checks, story organization, and reader-feedback tools make it easier to identify weaknesses and improve a draft. I particularly appreciate that the AI supports the writer instead of taking control of the creative process. The interface is straightforward, and the option to start for free makes it easy to explore. A valuable tool for both fiction and non-fiction writers.
