Find the contradictions across your series before a one-star review does.
StoryHelm reads every book you've written. Every character, timeline, promise, and world rule. It surfaces the continuity problems no author can hold in working memory. It never writes a word of your prose.
Founding cohort forming now · Invites go out in small weekly waves
By Book 4, the series remembers more than you can.
Eye colors change. A timeline slips a season. A magic rule bends to save a scene. Readers notice, and they say so in reviews. Series read-through pays your whole career, and continuity slips are what bleed it. No spreadsheet, wiki, or human memory tracks an entire saga. That gap is where series careers stall.
StoryHelm quotes both passages back to you, chapter and line. You decide which one is true. It never decides for you.
How it works
Three steps from a scattered saga to one canon that holds.
Import your series
Upload finished books and works in progress. StoryHelm parses chapters and scenes, then builds your Canon: characters, places, timelines, and world rules, extracted from your own pages.
41 agents read everything
Specialized agents across 7 workflows read the full text of every book: structure, pacing, voice, foreshadowing, timelines, world rules. Each finding arrives with the passages that prove it.
You decide what changes
You get a diagnostic report, not a rewrite. Fix what matters, dismiss what doesn't. The byline never moves.
What it catches
The problems readers screenshot, reviewers cite, and tired eyes skip.
Trait drift
Eye color, scars, ages, heights. The small physical facts readers keep a running ledger of.
Timeline contradictions
Two winters in one year. A pregnancy that lasts fourteen months. A crossing that outruns its map.
Broken world rules
The magic system that quietly bends in Book 3 to save a scene, and the readers who remember Book 1.
Voice drift
The blunt mercenary who starts speaking in court formalities by chapter twenty.
Dropped threads
Setups with no payoff. Payoffs with no setup. Foreshadowing health, scored by genre.
Pacing drag
Scene-level intensity mapping shows where readers skim, where they stall, and where the filler sits.
The editor's chair, not the writer's chair.
Most AI offers to write your book. StoryHelm refuses. It reads, checks, and reports. It never generates prose, never rewrites your sentences, never touches your voice.
Every flag comes with receipts: your own passages, quoted back with chapter and line. The judgment stays yours. So does every word.
The founding cohort is forming now.

Questions authors ask first
Will StoryHelm write any of my book?
No. That is the founding rule of the product. It reads and analyzes. It flags problems with quoted evidence from your own pages. The writing is yours, every word.
What happens to my manuscript?
Your manuscript stays yours. It is processed only to run your analysis and stored under your account. It is not used to train AI models. The full policy comes with your invite.
I'm three books into a series. Is it too late to start?
The opposite. Backlist import is the core of the product. Bring the published books, and StoryHelm builds the canon from what is already in print, then checks your work in progress against it.
What will it cost?
Public plans start at $14 per month billed annually. Founding cohort members lock founding-member rates before launch.
Do I need to publish on Amazon KDP?
No. KDP, wide, hybrid, or querying: if you are writing a multi-book story, this is built for you.
