The problem

Stuck in the middle of your draft?

You're too close to see it clearly. Arbento reads your whole story from the outside and shows you exactly what to fix next so you always know where to start.

Story memory · Codex

It never forgets a detail.

Arbento builds a living memory of your story every character, place, and rule you've written. When chapter nine contradicts chapter two, it tells you.

→ Characters, places and rules, tracked as you write.
→ Continuity flags the moment a detail breaks.

“She fixed him with her green eyes.” — Mira's eyes are recorded as brown in her Codex entry.

Beat analysis

Know what every scene is for.

Tag a scene to a story framework — Save the Cat, Three-Act, the Hero's Journey — and Arbento scores it, tells you what's working, what to fix, and exactly how.

→ A score and a verdict for the scene you're in.
→ Specific, line-level rewrite tips — never vague notes.

Catalyst · “The Map That Breathed”

A strong opening image with a clean final reveal, but the description can reach the emotional hook faster.

What works

✓ The Tuesday detail immediately establishes Mira's dry, observational voice.

✓ The handwriting reveal is placed at the end — it earns its weight.

What to fix

✕ The map's physical description runs long before the emotional hook arrives.

Rewrite tip

✎ Rewrite tip

Cut everything between “weighted the corners” and “It showed a city.” The objects don't matter — the city does. Get there faster.

Story health

See the gaps before a reader does.

A full structural read of your manuscript. Missing beats, pacing problems, your strongest scene — and the one thing to fix next.

→ Whole-manuscript analysis, not one paragraph at a time.
→ A single, clear next priority — so you always know where to go.

Story Health

A vivid premise and a clear catalyst, but the setup arc still needs its Debate and Break into Two beats.

Write the Debate beat — Mira needs a scene where she resists committing to the Glass City before she crosses into the second act.

Writing signals

Catch the scenes that drift.

Tone, readability, sentence rhythm, the words you lean on — all surfaced quietly as you write. Notice the moment a chapter stops sounding like you.

→ A tone fingerprint for every scene, against your usual voice.
→ Rhythm and overused-word signals, never in your way.
