Features
Every tool a novelist needs.
None that sound like a machine wrote it.
AIStoryHub gives you a full set of tools for plotting, character work, dialogue, and revision, plus a research-backed system for catching the phrases that give AI prose away. You stay the author. Ash does the rest.
Your editor
Revision that reads the whole manuscript.
Select a line and Ash sharpens it in place. Run an Editorial Pass and get margin notes on pacing, voice, and continuity, each with a confidence rating. Apply a Human Grit Pass when you want cadence that reads unmistakably human.
- Inline quick actions on any selection: Improve flow, Punch up dialogue, Simplify, Expand
- Editorial Pass notes across pacing, voice, continuity, and structure
- Every generation snapshots to Version History, so you can revert any edit
Draft and tune
Generate a chapter. Then dial in the voice.
Generate PRO writes a full chapter in one pass, pulling from your characters, lore, and Story Rules instead of a blank prompt.
Style Lab holds 33 voice controls. Paste in your own writing and extract a profile, or start from a premade literary style.
The Variables Engine
Story Rules that read the scene.
Write a Story Rule once and it pulls live data straight out of your story: any character, any location, any piece of lore, and conditional logic that changes what Ash does depending on who is actually in the scene.
Live variables
{{story_config.tense}}Reference your genre, tense, POV, or any character, location, or lore entry by name. Ash resolves it against the real story, every time it generates.
Conditional logic
{{#if}}Rules that only apply when they matter: if a character shares the scene, add a note. If not, the rule skips itself entirely.
A picker, not a guess
{{locations.…}}Search every variable and every named character, location, or item in your story, then insert the exact token. You never have to remember or mistype a name.
One rule, real conditional logic: tension notes only appear when both characters actually share the scene.
Search for any character or story element by name and insert the exact variable, no memorizing syntax.
Everything included
The complete toolkit.
Every tool below ships to every account. Bring a key or use the free built-in model, and you get the full set, not a locked tier of it.
Plot & Structure
Story Elements
Characters, locations, lore, organizations, items, and events live as their own pieces of your story. Reference any of them with @ while you write, and Ash pulls in the right details automatically.
Cohesion Check
A two-pass read of your full manuscript that checks continuity, structure, and recurring motifs, and tells you exactly where they break down.
Pacing Audit
Maps the rhythm of every chapter so you can see where the story drags or rushes before a reader does.
Tension & Stakes Map
Tracks stakes across the whole manuscript and flags the stretches where tension quietly disappears.
Subplot Tracker
Lists every subplot you've started and whether it's still alive, resolved, or forgotten.
Scene Purpose Audit
Flags scenes that aren't doing enough work to earn their place.
Theme Tracker
Follows your themes chapter by chapter and calls out where they drift or get heavy-handed.
Chapter Hooks Audit
Rates the opening and closing line of every chapter on whether it actually hooks.
Canon & Sandbox Chapters
Mark a chapter as sandbox to draft freely without it ever entering Ash's context. Flip it to canon when it's ready to count toward your real continuity.
Character Development
Character Arcs
Pick a character and get a three-pass audit of their arc: is the change earned, is it coherent, does it match who they were on page one.
Character Quick Add
Build out a character, name, role, importance, in seconds while you're mid-draft, without breaking flow to fill out a form.
Automatic character memory
Once a character exists, @-reference them anywhere and Ash writes with their established traits, history, and relationships in mind.
Dialogue & Voice
Dialogue Health Check
Reads dialogue across every chapter and tells you where characters start sounding like each other.
Voice Consistency Check
Checks that your narrative register holds steady from chapter to chapter instead of drifting.
Punch Up the Dialogue
Select any line and get it sharpened on the spot, no full-scene rewrite required.
Voiceprint & Style Lab
Dial in 33 style controls, pacing, diction, tone, POV, metaphor density, start from a premade literary style, paste in your own writing to extract a voice profile, or share and import styles from the community gallery.
The Showdown
A public, blind side-by-side of generic AI output against Voiceprint-tuned output. Judge for yourself which one reads like a person wrote it.
Editing & Revision
Generate PRO
Writes a complete chapter in one pass, using your characters, lore, and Story Rules as source material instead of a generic prompt.
Revise
Give Ash a specific instruction and get a targeted edit, not a full rewrite you have to comb through.
Human Grit Pass
An optional rewrite pass that varies sentence cadence and strips the phrasing patterns that read as AI-generated.
Editorial Pass
Structured notes across pacing, voice, continuity, dialogue, clarity, structure, and characterization, each with a confidence rating. Apply, dismiss, or jump straight to the line.
Inline quick actions
Select any passage and choose Improve Flow, Simplify, or Expand.
Version History
Every AI action saves a snapshot. Revert any change instantly, no lost drafts.
Project Checkpoints
Save a whole-project snapshot, story, world, and beats together, and restore it in one click if a session goes sideways. Publishing to the Community Hub is pinned to a checkpoint, so readers see a deliberate version, not your latest edit.
Feedback on every generation
Rate any AI output with a thumbs up or down to help tune what Ash gives you next.
Command palette & shortcuts
Press ⌘K to jump anywhere or run an action, or ? to see every keyboard shortcut for writing, navigation, and AI tools without leaving the keyboard.
Prose Quality Research
AI Slop Checker
A free public tool. Paste in any text and get it scored against known AI writing tells.
The Corpus of AI Clichés
A published, community-rated research corpus of 758 phrases and patterns common in AI-style prose, each with a confidence score.
AIisms
A rating game built on the corpus. Judge whether a snippet reads as AI-written, help grow the dataset, and climb the leaderboard.
Fiction Slop Index
A leaderboard scoring today's models on fiction-specific AI tells, benchmarked across scenarios and judged for how human the prose actually reads.
Voice Fingerprint Analyzer
Paste in a sample of prose and get a radar-chart breakdown of its voice: pacing, sensory balance, sentence rhythm, and more.
AIStoryHub Labs
Every research tool lives together at /labs, our free hub for testing prose against AI tells before you commit a style.
World-Building & Rules
Universes
Pre-built worldbuilding templates, complete with characters, locations, lore, and events, spanning fantasy, sci-fi, cyberpunk, romance, and thriller. Fork one into your own story and start writing.
Story Rules
Set persistent instructions once, genre, tone, POV, banned words, whatever matters to your story, and Ash follows them on every generation. Toggle any rule to apply by default or stay opt-in, and share one to the community gallery, or import a rule another writer has published.
Variables Engine
Reference any character, location, item, or lore entry by name inside a rule, and add conditional logic so a rule only fires when it's actually relevant to the scene.
Collaboration
Community Hub
Publish chapters to a public feed, browse by genre, react to other writers' work, and build a following.
EPUB download & share
Readers can download any published chapter as an EPUB, or share it by link or email straight from the community reader.
Private Groups
Invite-only circles for beta readers. Publish to the group, invite by email or token, and let readers comment without giving them edit access.
Export & Ownership
Export anywhere
Pull your work out as TXT, DOCX, or a full ZIP with every chapter and story element organized into folders. Your manuscript is yours, in a format any editor, agent, or printer can open.
