Ekte.ai er et norsk verktøy for AI-deteksjon og plagiatkontroll, utviklet med støtte fra NTNU og Center for Excellence in Education. Det identifiserer tekst skrevet av KI-modeller som ChatGPT, Claude og Gemini, med høy nøyaktighet og lav feilrate. Tjenesten er GDPR-kompatibel og tilbyr også faktasjekk, språkvask og kontrollspørsmål.

What is an AI detector?
An AI detector estimates whether text — and sometimes images — was generated by AI rather than a human. It analyzes patterns like word predictability and phrasing and returns a probability score. Detectors are used to screen essays, articles, and submissions, though none is perfectly accurate.
Core features to look for
- AI-vs-human probability score for text
- Sentence-level highlighting of flagged passages
- Support for common models (GPT, Claude, Gemini)
- Bulk or document upload checks
- Plagiarism checks in some tools
- Free tier and API access
Who uses AI detectors, and how

02
Image & content detection
Some tools flag AI-generated images or mixed human-AI content.
03
Free scans
Compare free detectors by word limits, accuracy claims, and daily quota.
04
API & bulk
Integrate detection into an LMS, CMS, or moderation pipeline.
How does an AI detector work?
AI detectors run classifier models trained on human and AI text. They measure signals like how predictable each word is (perplexity) and how uniform the phrasing is (burstiness), then output a probability. Because AI writing keeps improving, scores are estimates, not proof.
