Prose Craft Scoring
Fourteen quality metrics evaluate every scene — not just grammar, but sentence-level artistry. Rhythm, image density, dialogue authenticity, and narrative authority. The scoring system rewards the kind of prose that wins readers over on page one and keeps them thinking long after the last.
Thematic Depth Tracking
Literary fiction lives or dies by its thematic coherence. ProseEngine's Thematic Layer world state tracks symbolic threads, recurring motifs, and conceptual arcs across your entire manuscript. See where themes surface, where they go quiet, and where they need reinforcement.
Voice Preservation
Author Packs capture your specific prose fingerprint — sentence length patterns, diction range, degree of interiority, even your relationship with punctuation. Drift detection monitors AI-generated passages against your established voice and flags anything that reads like a different writer.
Narrative Distance Control
Literary fiction demands precise control over psychic distance — the gap between narrator and character. ProseEngine tracks Narrative Distance as a world state variable, so you can see exactly how close or far the camera sits across every scene and modulate it deliberately.
Multi-Voice Audiobook
Transform your finished manuscript into a professional audiobook with distinct character voices. AI detects who speaks each line — no manual tagging. Give your dialogue-driven scenes and internal monologues the vocal texture they deserve.
The Literary Fiction Quality Pipeline
Every scene passes through six stages designed to produce prose worthy of the literary fiction shelf — where craft is not optional.
Generate
AI writes your scene with literary sensibility — attention to image, subtext, and the weight of what goes unsaid. Not plot-first generation but prose-first.
Validate
Structure check for pacing and internal logic. Ensures the scene earns its length — no bloat, no rushed transitions, no moments that exist only to move plot forward.
Quality Gate
14 metrics including Emotional Impact, Prose Quality, and Thematic Resonance. Scenes below your threshold are automatically rewritten until they reach the standard you set.
Canon Enforcement
Keeps character histories, emotional states, and thematic commitments consistent. The detail your protagonist noticed in chapter two, the promise your narrator made in chapter five — nothing slips.
Drift Detection
Catches when voice shifts unexpectedly. If your restrained third-person narrator suddenly becomes confessional, or your lyrical prose turns workmanlike, you will know before any reader does.
Finalize
Polish pass for prose rhythm and sensory precision. Tightens language, deepens imagery, and ensures every sentence carries its weight — nothing decorative, nothing wasted.

Frequently Asked Questions
Can AI help write literary fiction without sounding generic?
Yes. ProseEngine does not impose a house style. Author Packs capture your specific voice — sentence rhythm, diction preferences, tonal register — and the AI generates within those constraints. The 14-metric quality scoring penalizes cliche and rewards originality, so output trends toward the distinctive rather than the formulaic. You direct; the AI assists.
How does ProseEngine preserve authorial voice?
Author Packs define your narrative voice at every level: sentence length distribution, vocabulary range, use of metaphor, degree of interiority, even punctuation habits. Drift detection monitors generated prose against your established voice profile and flags passages that deviate. The result is AI-assisted writing that reads like you wrote every word.
Does ProseEngine understand subtext and thematic layering?
ProseEngine tracks thematic threads across your entire manuscript through its Thematic Layer world state. Engagement presets for literary fiction emphasize subtext, narrative distance, and symbolic resonance. Quality scoring evaluates prose not just for surface clarity but for depth — the unsaid that gives literary fiction its power.
Can I write literary fiction with ProseEngine for free?
Yes. The free tier includes 3 books, the full scene editor, Focus Mode, and DOCX export. For AI generation, you can use Google Gemini's free tier, free models on OpenRouter, or run local LLMs — all at zero API cost. Paid plans start at €9/mo with a 14-day free trial.
