- 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. Free to try. Pro subscription unlocks AI analysis. --- Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
