Overleaf paper review extension with multi-agent backend

PaperDebugger is an AI-powered academic writing assistant that helps researchers debug and improve their research papers with intelligent suggestions and seamless Overleaf integration, without leaving the editor. It is powered by our custom MCP-based orchestration engine that simulates the full academic workflow Research → Critique → Revision.
This enables multi-step reasoning, reviewer-style critique, and structured revision passes beyond standard chat-based assistance.
