- Arbento is story intelligence for writers.
It reads your manuscript, learns your characters, and thinks with you about structure scene by scene.
- The AI that knows your whole story
Most writing tools see one sentence at a time. Arbento sees the whole manuscript. Every scene you write, every character you introduce, every rule you establish Arbento reads and remembers it. When something contradicts, it says so. When a scene is missing its structural purpose, it tells you specifically what to fix.
- Beat analysis
Tag any scene to a story framework: Save the Cat, Three-Act Structure, or Hero's Journey. Arbento evaluates whether the scene delivers what that beat requires: a score, what's working, what to fix, and a rewrite tip drawn from your actual prose. Not generic advice. Analysis of your specific scene.
- Codex AI intelligence
Build your story's Codex: characters, places, world rules. Arbento reads it before every analysis. It catches continuity errors (wrong eye colour, destroyed objects reappearing), flags unregistered characters as they appear in your prose, notices when a character's behaviour contradicts their arc, and surfaces forgotten threads you haven't returned to.
- Editorial feedback
A developmental editor's read of your prose. What's landing, what one thing would improve it, specific language corrections, and what this scene sets up for what follows. Honest, specific, based on your writing not a generic critique.
- Story health
A full structural read of your entire manuscript. Missing beats, pacing observations, your strongest scene, and the single highest-priority thing to fix next. Developmental editing at a fraction of the cost.
- Writing signals
Readability score, sentence rhythm, tone fingerprint, overused words, echo detection. Every scene, always.
- For iPhone, iPad and Mac
Write on iPhone on the train. Continue on Mac at your desk. Everything syncs fast, reliable, and available offline.
Arbento is for writers who want to understand their story better, not writers who want AI to write it for them.

What I like the most about this AI app is it doesn’t lecture or refuse to help. This AI app understands the culture and will help to refine my often harsh thoughts without reprimand. One suggestion to improve the app is for it to create images. If you don’t speak ‘politely’ and want to put your thoughts to paper, this app is the best so far. I tried the popular ones, and I couldn’t use them for half the things I wanted to write.

Thanks for the great review!
Probably works for essays

I tried to use this to help me write stories. I tend to do that when I am struggling with a story. However I tried various different ways but everytime I tried to put in a ‘plot’ it would just continue what I wrote… which didn’t make sense because that is not what a plot description means.
