- 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/

Verdict

The call

The clearest difference is review sentiment: Chat AI at 97% against Writing App's 25%. Chat AI also leads on iOS requirement (13.0 vs 26.0). Writing App's advantage is rating (4.6 vs 4.2) and ratings volume (92 vs 12). On price, update cadence, ads and in-app purchases there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Chat AI sells 3 in-app purchases, starting at $9.99 per month and Writing App sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Writing App holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Writing App has 92 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 97% of Chat AI's written reviews are positive against 25% of Writing App's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Chat AI ships an update fortnightly, Writing App every 2 weeks. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
