How OmniDetect Works

We don't guess — we verify with multiple sources.

Three Steps to Certainty

Step 1

You paste your text

Paste up to 50,000 characters. Your text is sent directly to detection engines and never stored in our database. Only a SHA-256 hash is kept for caching.

Step 2

Multiple engines analyze independently

OmniDetect sends your text to GPTZero and Originality.ai simultaneously. Each engine uses different AI detection models and methodologies, providing independent assessments.

Step 3

You get a consensus report

Results are aggregated into an OmniScore (0-100). When engines agree, confidence is high. When they disagree, you know to investigate further. Our AI Writing Coach explains flagged patterns and suggests improvements.

Our Detection Engines

GPTZero

Pioneer in AI detection. Uses perplexity and burstiness analysis to identify AI-generated text. Widely trusted by educators.

Strong academic text detection

Originality.ai

Commercial-grade AI content detector optimized for content marketing. Detects GPT-4, Claude, Gemini, and other modern LLMs.

Broad LLM model coverage

Why Multi-Engine Consensus?

No single AI detector is perfect. Each has strengths and blind spots.

  • GPTZero may miss content from newer models that Originality.ai catches
  • Originality.ai may flag legitimate academic writing that GPTZero passes
  • When both engines agree on 'human' — that's strong evidence
  • When engines disagree — that's valuable information too

OmniDetect acts as your auditor: we don't produce a diagnosis, we verify it across multiple independent sources.

Privacy by Design

No text storage

Your original text is never saved to our database. It's sent directly to detection engines and discarded.

SHA-256 hashing

Only a cryptographic hash of your text is stored — for caching purposes. The hash cannot be reversed to recover your text.

No training data

Your text is never used to train AI models. Detection engines receive your text for analysis only.

Honest Limitations

We believe in transparency. Here's what you should know:

  • AI detection technology is probabilistic, not definitive. Results represent likelihood, not certainty.
  • Detection accuracy varies by text length. Longer texts (500+ words) produce more reliable results.
  • Heavily paraphrased AI text may evade detection. No detector catches everything.
  • ESL (English as a Second Language) writers may receive higher AI scores due to simpler sentence structures.
  • Results should complement — not replace — human judgment.
