A 90-second walk through a full authenticity scan.
Everything you need to read between the lines
Evidence over verdicts — every score shows its work.
Forensic Signal Scores
Burstiness, perplexity, cliché density, and self-reference — each axis scored 0–100 so you see exactly why a verdict landed where it did.
Flagged Passage Highlights
The exact spans that read machine-written are highlighted inline, each with a short reason — boilerplate openers, buzzword stacks, templated closers.
Text & Image Analysis
Paste prose or drop in a photo. Images get checked for texture entropy, edge coherence, lighting model, and diffusion frequency fingerprints.
Tunable Strictness
Lenient, balanced, or strict shifts the verdict threshold to match your stakes — a casual review and an academic-integrity check aren't the same call.
The AI upgrade that changes everything
Today Litmus scores with on-device forensics. Tomorrow — real model fingerprinting and exportable evidence reports.
Live Model Fingerprinting
Go beyond a score and estimate which model family likely produced the text — and how heavily it was edited afterward.
PlannedAuthor Style Baseline
Learn a person's real writing fingerprint so Litmus can flag ghostwritten or AI-assisted passages against their genuine voice.
PlannedDocument & PDF Scanning
Batch-scan whole documents, essays, and PDFs at once, with a heat-mapped overview of every suspect section.
PlannedCited-Evidence Reports
Export a clean forensic report — signals, flagged spans, and methodology — for academic integrity boards and editors.
