Sure

An AI-augmented intelligence layer that transforms how you write and verify information online

"Where AI meets authenticity - because every word should be backed by truth"

Sure is the first AI-augmented intelligence layer that seamlessly integrates into your writing workflow, providing real-time fact-checking and comprehensive quality assessment as you type. Built with cutting-edge AI technology, Sure acts as your intelligent writing companion, automatically detecting factual claims, verifying their accuracy, and providing detailed quality insights to help you write with confidence and authority.

Think of Sure as your personal fact-checking assistant that never sleeps, never gets tired, and never misses a claim.

✨ Features

🔍 Real-time Fact-Checking

• Instant Analysis: Monitors text as you type in any editable field
• Smart Detection: Uses advanced BERT models to identify factual claims
• AI-Powered Verification: Leverages Grok-3 and web search for accurate fact-checking
• Visual Feedback: Highlights claims with color-coded indicators based on accuracy

📊 Comprehensive Quality Assessment

• Multi-Dimensional Scoring: Evaluates content across 5 key dimensions:

  • Source Quality (25%): Credibility of cited sources
  • Claim Density (15%): Appropriate balance of claims to content
  • Confidence Consistency (10%): Reliability of assessment methodology
  • Evidence Support (10%): Proportion of claims backed by sources

🎯 Intelligent Source Evaluation

• Premium Sources: Reuters, AP, BBC, Nature, NEJM (+100 points)
• Quality Sources: NYT, WSJ, CNN, Wikipedia (+80 points)
• Standard Sources: Other verifiable sources (+60 points)
• Smart Prioritization: Investigative journalism over opinion content

🚀 Advanced Technology Stack

• Multi-Query Search: Investigative, news, and fact-checking strategies
• Coreference Resolution: Better understanding of complex text

🎨 Visual Experience

• Color-Coded Highlights:
  • 🟢 Green: Factual claims
  • 🟡 Yellow: Somewhat accurate claims
  • 🔴 Red: False or unverified claims
• Interactive Tooltips: Click highlighted claims for detailed information
• Quality Widget: Real-time scoring and grade display
• Loading Indicators: Smooth user experience with progress feedback

🛠️ Installation

Prerequisites

• Node.js (v16 or higher)
• Python (3.8 or higher)
• Chrome Browser

Quick Start

1. Clone the repository:

   git clone https://github.com/yourusername/sure.git
   cd sure

2. Set up the server:

   cd server
   uv sync
   uv run fastapi dev main.py

3. Build the extension:

   cd ../sure-extension
   npm install
   npm run build

4. Load in Chrome:

   • Open chrome://extensions/
   • Enable "Developer mode"
   • Click "Load unpacked"
   • Select the sure-extension/dist folder

📈 How It Works

1. Text Monitoring

Sure continuously monitors editable fields (<input>, <textarea>, contenteditable) as you type, using intelligent debouncing to avoid unnecessary API calls.

2. Claim Detection

When you pause typing, Sure uses a custom BERT model (NeelKondapalli/claim-bert) to identify factual claims in your text.

3. Fact Verification

Each claim is analyzed using:

• Grok-3 AI: Advanced reasoning and fact-checking
• Web Search: DuckDuckGo integration with source prioritization
• Vectorstore Context: Enhanced understanding from processed content

4. Quality Assessment

Your content receives a comprehensive score based on:

• Factual accuracy of claims
• Quality of sources used
• Appropriate claim density
• Consistency of confidence scores
• Evidence support for claims

5. Visual Feedback

Results are displayed through:

• Highlighted claims with accuracy indicators
• Interactive tooltips with detailed information
• Real-time quality scoring and grading
• Actionable improvement suggestions
