🔍 In an age of misinformation, FactFlow empowers users to navigate online news with confidence.

FactFlow is an intelligent browser extension designed to analyze and validate news articles in real-time.
By combining the power of Natural Language Processing, source credibility checks, and AI-based cross-referencing,
FactFlow delivers a layered analysis to help you identify fake, misleading, or unverifiable content — directly as you browse.

Whether it's political headlines or trending stories, FactFlow helps you verify before you trust.

• 🧠 3-Layered Verification System

  • Pattern-based ML model trained on LIAR dataset
  • Source credibility score using MBFC database
  • Factual cross-checking with real-time LLM support

• ⚡ One-Click Analysis

  • Scrapes and processes the current web page automatically

• 🟩 Credibility Verdict Bar

  • Displays clear verdicts like: Fake, Soft Fake, Likely Real, Uncertain

• 🌐 Chrome Extension UI

  • Minimalistic interface built with React + Tailwind + ShadCN
  • Circular animated progress loader and hover effects

• 📡 FastAPI Backend

  • Unified API that integrates model inference, source scoring, and LLM calls

FactFlow analyzes content using three distinct yet complementary layers:

• Uses a fine-tuned RoBERTa-Large model trained on the LIAR dataset
• Analyzes language style, semantic patterns, exaggeration, and bias indicators

• Looks up the article’s source in the Media Bias/Fact Check (MBFC) database
• Uses source credibility scores and bias ratings to assess trustworthiness

• Utilizes the Gemini LLM API to verify key claims
• Checks if claims are supported or contradicted by factual sources across the web

✅ Final Verdicts like Fake, Soft Fake, or Likely Real are assigned by a custom decision engine that aggregates all three layers.

🎥 The extension scans the page, runs all 3 verification layers in real-time, and displays a final verdict with animated feedback and progress tracking.

• Model: Fine-tuned BERT on LIAR Dataset
• Accuracy: 87.3%
• F1 Score: 0.88
• Data: 15k labeled political statements

The final credibility verdict is determined by a custom decision engine that synthesizes all three layers:

🧠 These verdicts are dynamically computed using a hybrid rule-based and AI-supported decision engine.
