PDF Data Extraction & Comparison: Claude vs Gemini

This n8n workflow enables direct PDF data extraction and processing using Anthropic's Claude 3.5 Sonnet and Google's Gemini 2.0 Flash models, eliminating the need for separate OCR steps. It begins by downloading a PDF from Google Drive, converting it to base64, and sending the encoded file to both AI models with a customizable prompt for extraction and transformation.

Key benefits include streamlined one-step processing, side-by-side comparison of AI outputs for accuracy, latency tracking, and cost analysis in a dedicated dashboard. Users can deactivate one API if preferred, making it flexible for single-model use. Setup requires Google Drive integration, Claude/Gemini API keys, and prompt customization.

Ideal use cases: Automating invoice/receipt data pulls, research document summarization, form field extraction, or benchmarking LLMs for enterprise document workflows. Saves time on multi-tool chains and provides empirical data on model performance for AI selection.
