# 🧭 TruthLens – Misinformation-Aware RAG |
|
|
|
|
|
TruthLens is a **fact-checking AI demo** that shows how modern GenAI can be made **responsible, transparent, and safe**. |
|
|
It verifies controversial claims (vaccines, climate, elections, etc.) using **retrieval-augmented generation**, checks its own answers for **faithfulness**, and applies **safety filters**. |
|
|
|
|

|
|
|
|
|
## 🚀 How it works |
|
|
1. **Input a claim/question** |
|
|
Example: *“Did humans cause global warming?”* |
|
|
|
|
|
2. **Retrieve sources** |
|
|
The app looks at trusted sources (WHO, IPCC, election reports). You can also paste your own text. |
|
|
|
|
|
3. **Generate grounded answer** |
|
|
TruthLens writes an answer with [1], [2] style citations from those sources. |
|
|
|
|
|
4. **Self-check** |
|
|
It tests how well the answer actually matches the sources (faithfulness score). |
|
|
|
|
|
5. **Safety filters** |
|
|
- Removes personal info (PII redaction). |
|
|
- Flags toxicity levels if the language is harmful. |
|

## 🛠️ Tech stack |
|
|
- **Gradio** (UI & deployment) |
|
|
- **Transformers** (Flan-T5 generation, DeBERTa NLI, BERT NER, Toxic-BERT) |
|
|
- **SentenceTransformers** (MiniLM embeddings) |
|
|
- **CrossEncoder** (MS-MARCO reranker) |
|
|
- **scikit-learn / pandas / numpy / matplotlib** |
|
|
|
|
|
All models are **CPU-friendly**, so the demo runs in a free Hugging Face Space. |
|
|

|
## 🌍 Why it matters |
|
|
- Tackles **misinformation** around health, climate, and politics. |
|
|
- Demonstrates **responsible AI practices** (grounding, self-checking, safety). |
|
|
- Shows how a **Lead AI Developer** designs not just models, but **systems** ready for production. |
