AI-powered backend API for screenshot analysis and intelligent note management. Built for research sessions where users capture screenshots and receive AI-generated insights, summaries, and interactive note editing.

This backend provides RESTful API endpoints that power the Relay It application:

• Screenshot Analysis - Analyzes uploaded images using Google's Gemini 2.0 Flash to extract text, identify entities (hotels, restaurants, products, etc.), and generate structured insights
• Session Management - Organizes screenshots into sessions with metadata tracking and retrieval
• AI Summarization - Creates intelligent summaries from multiple screenshots and entities within a session
• Interactive Chat - Enables users to edit markdown notes via natural language commands or ask questions about their research
• Regeneration - Re-analyzes screenshots with refined prompts for improved results

• Next.js 16 - API routes with Edge Runtime for fast global deployment
• TypeScript - Full type safety across all endpoints
• Gemini 2.0 Flash Exp - Google's latest AI model for vision and text generation
• Supabase - Authentication and PostgreSQL database
• Vercel - Serverless deployment platform
