- Recommendica uses a multi-turn Relevance Agent to dynamically refine search queries and filter out irrelevant papers.
- The platform integrates live arXiv API fallback to ensure up-to-date results when local coverage is low.
- Its pay-what-you-want donation system, powered by Paddle, supports sustainable development.
The Challenge: Why Recommendica – Agentic Research Paper Recommender Was Built
Traditional semantic search engines often return top-K results even when they are irrelevant, leading to RAG systems generating answers based on unrelated papers. Additionally, local databases are static and cannot provide access to recent papers. Recommendica addresses these challenges by introducing an active, multi-turn Relevance Agent and a live arXiv fallback mechanism.
Core Architecture & Technical Stack Deep-Dive
Recommendica is built on a robust tech stack, including Django/FastAPI for the backend, React for the frontend, ChromaDB for vector storage, and arXiv.org REST API for live fallback. The platform leverages Docker Compose for containerization and integrates Paddle for donations.
Parallel Generation Mechanics
To optimize performance, Recommendica splits retrieved papers into groups, processing them concurrently using up to GENERATION_MAX_WORKERS (default 3). This approach reduces latency and cost while maintaining high accuracy.
Key Features Breakdown & Practical Benefits
Multi-turn Relevance Agent
The Relevance Agent grades document relevancy, filters out unrelated papers, and dynamically rewrites queries to ensure high-quality results. This iterative process continues until sufficient relevant papers are found.
Live arXiv Fallback
When local search yields insufficient results, Recommendica queries the live arXiv API, grades the results, and blends them into the final context window. This ensures users always receive the most relevant and up-to-date papers.
Real-World Use Cases & Applications
Recommendica is ideal for academic and industry researchers seeking relevant scientific literature without semantic hallucinations. It also supports automated multi-paper literature reviews and citation synthesis.
How It Works: Step-by-Step Workflow
- The Relevance Agent retrieves candidate papers from the local database.
- It grades candidates against the user’s query and filters out irrelevant papers.
- If insufficient papers are found, the agent rewrites the query and performs a secondary search.
- When local coverage is low, the system queries the live arXiv API and grades the results.
