Maps, bibles, and canon
Storysnap
From the team behind Plottr, and deliberately separate from it. Plottr the outlining app has no AI. Storysnap uploads a Word or PDF manuscript and returns a visual outline, character and world notes, and a Plottr file. Expect missed details and the occasional invented emphasis. It reads; it does not write the next chapter.
Best for
Writers who already think in Plottr and want a first-pass story bible pulled out of a finished draft.
Pricing
Usage-based. Pay per manuscript, with bulk credits. Credits are sold as non-expiring. This is not a monthly writing app.

Writer's Toolbelt review
Storysnap
From the makers of Plottr. Upload a finished manuscript and get a visual story-structure analysis and a book bible, priced per book.
- per book
- per book in bulk
- manuscripts used to train AI (vendor policy)
What it is
StorySnap is built by Plottr, the plotting software company. Instead of writing for you, it analyses a manuscript you've already written. It maps your story structure visually and builds a book bible of characters, places and details. StorySnap states it never trains AI on uploaded manuscripts. You pay per book with credits that never expire, and add-ons are available.
Who it's for
- Series authors who need a bible for a backlist they wrote without one.
- Authors revising, to check pacing and structure against a visual map.
- Writers wary of generative AI who still want analysis.
Key features in practice
- Visual story structure of your uploaded book.
- Book bible generated from the text.
- Add-ons for extra analyses.
- A Plottr connection, useful if you already plot in Plottr.
Pricing (checked 14 October 2026)

- Compare the structure map with your intended beats during revision.
- Correct the bible by hand. Automated extraction can miss nuance.
Strengths

- A clear no-training promise.
- No subscription.

Editing
AutoCrit
Fiction editing reports for dialogue, pacing, repetition, and overused phrasing, plus a story analyzer and an AI reader you can steer with instructions. The reports compare your draft with genre tendencies, which is a clue, not a verdict. It will not write the book for you.
Best for Novelists who want genre-aware notes on a complete draft, not a chatbot that continues the scene.
SubscriptionFictionEditing
Fictionary
Story-structure software that visualizes a story arc and includes Edwina, an AI instructor for scene-level feedback. The useful part is seeing whether the draft has a shape. The classes, if you buy them, are people. Do not confuse the two.
Best for Novelists who want structure feedback while outlining and revising, with an optional human class on the side.
SubscriptionFictionDrafting
LivingWriter
A manuscript workspace for books and screenplays: boards for structure and elements, outlines, and export to DOCX, PDF, EPUB, and Kindle. Optional AI can chat with the draft, rewrite, analyze, outline, convert a chapter to a screenplay, or sketch a cover, and the vendor says your manuscript is not used to train models. Free and Pro cap those requests hard, and this is still a general writing desk rather than a fiction-tuned co-writer like Sudowrite.
Best for Authors who want planning boards, a manuscript, and optional AI in one app, including screenwriters.
