OCR ResearchX – Autonomous Deep Research AI Agent
ResearchX is a production-ready autonomous research agent that performs end-to-end research with minimal human input.
Instead of simply answering questions, the agent plans research tasks, searches multiple trusted sources, evaluates information quality, retrieves supporting evidence, and generates structured reports with citations.
Built using a multi-agent architecture, the system combines planning, retrieval, tool calling, memory, and iterative reasoning to handle complex research tasks while reducing hallucinations through grounded retrieval and verification.
Features:
Autonomous Planning
Multi-Agent Workflow
Web Search Integration
PDF Analysis
RAG Pipeline
Citation Generation
Long-Term Memory
Report Generation
Source Verification
