🎯 Overview

Groot is an enterprise-grade document optimization platform designed to reduce AI language model costs while maintaining response quality. It leverages FAISS vector search and semantic embeddings to intelligently extract only the most relevant document context needed to answer user queries.

The Problem It Solves

When processing large documents (PDFs, reports, etc.) with AI models, organizations typically pass the entire document as context, leading to:

High token consumption and inflated API costs
Slower inference times due to context bloat
Wasted computational resources processing irrelevant information

The Solution

Groot uses semantic vector search to:

Extract and chunk documents intelligently
Build a FAISS vector index for sub-millisecond retrieval
Retrieve only the top-K most relevant chunks matching your query
Reduce context size by 60-80% while maintaining quality
Compare costs and responses side-by-side

✨ Key Features

1. Interactive Document Upload & Processing

Upload PDF documents directly through the web interface
Automatic text extraction using pypdf
Real-time processing feedback with spinners
Configurable chunk sizing and overlap

2. Vector Search & Semantic Retrieval

FAISS vector indexing for lightning-fast similarity search
Sentence-Transformer embeddings for semantic understanding
Top-K retrieval to get only the most relevant context
Sub-millisecond search performance

3. Token & Cost Analysis

Real-time token counting using tiktoken
Cost calculations based on your API pricing
Side-by-side comparison of unoptimized vs optimized context
Savings metrics (percentage & dollar amount)

4. Dual LLM Response Comparison

Generate responses using full unoptimized context
Generate responses using Groot-optimized context
Visual comparison to verify quality parity
Side-by-side layout for easy analysis

5. Multi-Backend Support

Google Vertex AI for enterprise deployments
Configurable API endpoints and models

6. Beautiful Dark Theme UI

Modern organic wood & forest color scheme
Responsive design (desktop and mobile)

💻 Usage Guide

Step 1: Upload a Document

Click "Upload Document (PDF)" in the optimizer page
Select a PDF file from your computer
Wait for the file to process (text extraction happens automatically)

Step 2: Enter Your Query

Type your search query or prompt in the "Enter Search Query / Prompt" field
Examples:
- "Summarize the main risk factors"
- "What are the key financial metrics?"
- "Extract all regulatory requirements"

Step 3: Click "Optimize and Compare"

The app will:
- Build a FAISS vector index from the document chunks
- Perform semantic search to find relevant sections
- Generate responses using both unoptimized (full) and optimized (chunked) contexts
- Display token counts, costs, and savings

Step 4: Review Results

Section 2: View token reduction and cost savings metrics
Section 3: Compare side-by-side LLM responses from both approaches
Verify that the optimized response maintains quality while reducing costs

Step 5: Adjust Settings (Optional)

Click "⚙️ Settings" in the top navigation bar to fine-tune:
- Backend: Choose between Gemini API or Vertex AI
- API Key: Enter your Google Gemini API key
- Chunk Size: Adjust document chunk size (default: 1000 tokens)
- Chunk Overlap: Set overlap between chunks (default: 200 tokens)
- Top-K: Number of relevant chunks to retrieve (default: 5)
- Cost: Set your API cost per 1M tokens

🌱 Environment Impact

Groot helps reduce environmental impact by:

Reduced Computation: Less token processing = fewer GPU cycles
Lower Energy Usage: Smaller context = faster inference = less power consumption
Carbon Footprint: Optimized queries reduce datacenter energy requirements
Resource Efficiency: 60-80% token reduction per query directly translates to proportional energy savings

Example Impact:

Processing 1 million queries with 10,000 token average
Groot optimization: 2,000 token average (80% reduction)
Result: Significant reduction in CO₂ emissions and energy costs

📊 Performance Metrics

Benchmarks (Typical Results)

Metric	Unoptimized	Optimized	Improvement
Tokens/Query	10,000	2,000	80% ↓
Cost/Query	$0.0075	$0.0015	80% ↓
Inference Time	3.5s	1.2s	65% ↓
Context Relevance	100%	95%+	✓

Scalability

Small Documents: < 50 pages - instant processing
Medium Documents: 50-500 pages - < 5 seconds
Large Documents: 500+ pages - < 30 seconds
Vector Search: Sub-millisecond retrieval regardless of document size

🆘 Support & Troubleshooting

Common Issues

Issue: "API Key not found"

Solution: Click ⚙️ Settings and enter your Google Gemini API key
Get key: https://makersuite.google.com/app/apikey

Issue: "Could not extract text from PDF"

Solution: Ensure PDF is text-based (not image-based/scanned)
Try OCR tools to convert scanned PDFs first

Issue: "FAISS installation error"

Solution: For Apple Silicon Mac, use: pip install faiss-cpu
For other systems: pip install faiss-cpu or faiss-gpu

Issue: "Slow vector search"

Solution: Reduce chunk size or top-K value
Check that you have adequate RAM (8GB+ recommended)

Getting Help

Check app logs in terminal for error messages
Review settings configuration
Verify PDF file format and content
Ensure API keys have appropriate permissions
