Privacy-First Local AI Content Detection
TinyWeb's AI Content Checker is a free, secure utility designed to analyze text and estimate the likelihood that it was written by generative artificial intelligence models like ChatGPT, Claude, or Google Gemini. Unlike commercial AI detectors that upload your text to cloud servers (which could breach corporate privacy or leak academic drafts), our tool operates 100% locally in your web browser. Your data is processed entirely in memory and never leaves your computer.
How Client-Side AI Detection Works
Generative AI models write in patterns optimized for statistical probability. This creates distinct linguistic signatures. The TinyWeb detector measures these signatures through two core metrics: Perplexity (text predictability) and Burstiness (structural variation). Humans naturally write with high sentence-length variation and unpredictable vocabulary. AI models, conversely, prefer high-probability word sequences and uniform sentence structures. By analyzing these traits client-side, we calculate an AI probability index and highlight sentences that appear computer-generated.
Why Choose an Offline AI Detector?
Many academic institutions, publishers, and companies require strict confidentiality when analyzing reports, code, or drafts. When you paste your text into typical detection portals, it is often saved in their databases or logged. Using local JavaScript analysis, TinyWeb provides a fast and secure alternative that preserves your intellectual property. It is completely unlimited, free of subscriptions, and does not require an account.
