# TruthLens AI – Project Description

I built **TruthLens AI** to help people check whether the information they read or hear is actually true, instead of just trusting what AI tells them.

You can type a claim, use your voice, paste text, upload a document, or provide a website link. TruthLens extracts the claims, searches the live web, and checks them against real sources.

**What makes TruthLens different is how it verifies information.**

Instead of relying on one AI model to give an answer, I built a system where different AI agents examine both sides of a claim. One looks for supporting evidence, another challenges it, and a final judge makes a decision.

The system also:

- Reads actual web pages instead of relying on search summaries.
- Shows the original evidence, citations, and confidence levels.
- Detects and isolates suspicious instructions hidden in websites or documents.
- Gives clear verdicts, including Supported, Contradicted, Misleading, Outdated, and Unverifiable.
- Shows disagreements and research limitations instead of pretending to know everything.

**The goal is to make AI verification more transparent and trustworthy.**

TruthLens is designed for students, researchers, journalists, and everyday people who want to check information before believing or sharing it.

I wanted to build something that doesn't just give you an AI-generated answer, but actually shows you the evidence behind that answer so you can make your own judgement.
