The literary
AI‑detector
that doesn't punish Hemingway.
Generic detectors flag minimalist prose as AI. Slopsleuth runs five audits calibrated specifically for fiction — tested against published human novels from 1895 to today. None falsely flagged.
“It was a good fight. Not bad. Just enough. He had not expected the boy to fight at all.”
Tested, not promised
Five published human novels.
None flagged as AI.
We ran public-domain literary fiction from 1895–1926 — Crane, Fitzgerald, Hemingway, Anderson — alongside a Claude-generated thriller written cold for benchmarking. The gap is reproducible.

Three audiences
Built so real authors don't get killed by an algorithm.
For authors
Audit your own draft before submission. Find the AI-prose tics you didn't know you'd absorbed — even if you wrote every word yourself. Your minimalist style won't be punished.
For literary agents
Triage the slush pile with confidence. Defensible, transparent audits — every flag explained, every passage shown. No black-box percentage you can't defend in a rejection letter.
For publishers
U.S. copyright law denies protection to AI-generated text. Catch hybrid manuscripts before contract — our voice-variance audit detects bimodal patterns whole-manuscript averages mask.
How it works
Five audits. Every flag is explainable.
No black-box statistical magic. Each audit measures a specific stylistic pattern documented in current AI prose, with thresholds calibrated against published human fiction.
Not-X Fragments
Hedge fragments like “Not because he was brave. Because his legs wouldn’t move.” The most common AI tell in modern fiction prose.
Body-Part Clusters
When the same body part (chest, jaw, throat) is hammered repeatedly within 10 paragraphs. AI reaches for physical anchors humans don’t.
Dialogue Texture
Real human dialogue is rough — fillers, restarts, mishearings. AI dialogue is unnaturally clean. We measure the absence.
Stock AI-Phrasings
“The way grief lives in objects.” “The kind of dead that meant…” Two constructions show 45–122× separation between AI and human prose.
Voice Variance
Per-chapter audit that detects hybrid manuscripts — half-human, half-AI. Bimodal patterns reveal the seams that whole-manuscript averages mask.
Why we exist
Generic detectors weren't built for fiction.
Hemingway scored 73% AI
- ✗ Trained on average internet text — minimalist prose looks "AI-like"
- ✗ Single percentage score with no explanation
- ✗ Cannot defend rejections — "73% AI" isn't actionable
- ✗ Misses hybrid manuscripts — averages hide the seams
Hemingway scored 7/100 — light signals
- ✓ Calibrated against five published human novels (1895–1926)
- ✓ Five transparent audits — every flag shown with the passage
- ✓ Recommended-action panel — "Read normally" / "Read with scrutiny"
- ✓ Voice-variance audit detects hybrid AI/human chapters
