AI PDF Data Extractor Agent: Compare Claude 3.5 Sonnet & Gemini 2.0 Flash

Unlock Advanced PDF Data Extraction with this AI Agent

This n8n workflow empowers you to effortlessly extract information from PDF documents using cutting-edge AI models. It fetches a PDF from your Google Drive, prepares it, and then sends it to both Anthropic's Claude 3.5 Sonnet and Google's Gemini 2.0 Flash for data extraction based on your custom prompt. This unique setup allows you to directly compare the performance, accuracy, and output of these two leading LLMs for your specific PDF processing needs, all within a single, streamlined automation. This AI Agent has the ability of 'intelligent document processing' and 'comparative AI analysis'.
