TruthLens is a free AI-generated content detection platform built for everyone — not just researchers or developers. Whether you're a student, journalist, educator, or curious reader, TruthLens helps you verify whether text or images were created by an AI tool.
Unlike other tools, TruthLens provides sentence-level analysis so you can see exactly which parts of a text are likely AI-written — not just a single score for the whole document.

Your privacy guaranteed
A combination of machine learning models and established forensic techniques working together.
Our text detector uses a fine-tuned DeBERTa-v3 model trained on millions of human and AI-written samples.
Perplexity Analysis
AI text is highly predictable — low perplexity scores indicate machine generation
Burstiness Scoring
Humans write in bursts of short and long sentences. AI writes uniformly
Sentence Classification
Each sentence is scored individually so you can pinpoint AI-written sections
DeBERTa-v3 Model
State-of-the-art transformer trained on GPT-4, Claude, Gemini and Llama output
Three research-backed forensic techniques alongside a vision transformer model to detect signs of AI generation.
EXIF Metadata Forensics
Real photos contain camera metadata. AI images often lack it or show editing software traces
Error Level Analysis (ELA)
Based on Krawetz (2007) — detects recompressed or edited regions by comparing compression artifacts
Noise Pattern Analysis
Real cameras produce stochastic sensor noise. AI images have unnaturally smooth patterns
Image Type Detection
Identifies photos, illustrations, screenshots and documents — applying the right analysis for each
