- Recommendica uses a multi-turn Relevance Agent to filter irrelevant papers and dynamically reformulate search queries.
- It integrates a live arXiv API fallback to ensure up-to-date results when local coverage is low.
- The platform features a pay-what-you-want donation system via Paddle to support its operations.
- Designed for academic and industry researchers, it prevents hallucinations by ensuring source document adherence.
The Challenge: Why Recommendica – Agentic Research Paper Recommender Was Built
Traditional semantic research search engines often return top-K results regardless of relevance, leading to RAG systems generating answers based on unrelated papers. Additionally, local research databases are static and cannot provide insights into recent papers that were never ingested. Recommendica addresses these challenges by implementing an active, multi-turn Relevance Agent and a live arXiv API fallback.
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 local document storage, and the arXiv.org REST API for live fallback searches. The system leverages Docker Compose for containerization, ensuring scalability and ease of deployment.
Service Orchestration & Control Flow
The Django REST API communicates with the React frontend, coordinating interactions with ChromaDB, Paddle Gateway, and the arXiv API. Concurrent workers handle parallel generation tasks, while rate limiters and circuit breakers protect external dependencies.
The Relevance Agent Architecture
The Relevance Agent manages the search execution, dividing it into distinct blocks: query checking, local search, grading loop, arXiv fallback, and generation engine. This ensures that only relevant papers are included in the final context window.
Key Features Breakdown & Practical Benefits
Multi-turn Relevance Agent
The Relevance Agent grades document relevancy and dynamically reformulates search queries, ensuring that only pertinent papers are included in the results.
Live arXiv API Fallback
When local coverage is low, the system queries the live arXiv API, grading and merging the results into the final context window. This ensures up-to-date information is always available.
Pay-What-You-Want Donations
Recommendica integrates Paddle’s pay-what-you-want donation system, allowing users to support the platform financially. This feature offsets the costs associated with LLM and embedding infrastructure.
Real-World Use Cases & Applications
Recommendica is invaluable for academic and industry researchers who need to discover relevant scientific literature without semantic hallucinations. It also supports automated multi-paper literature reviews and citation synthesis.
How It Works: Step-by-Step Workflow
Recommendica’s workflow begins with a pre-retrieval query checker to filter out invalid inputs. The Relevance Agent then retrieves and grades candidate papers, dynamically rewriting queries as needed. If local coverage is insufficient, the system queries the arXiv API and merges the results. Finally, parallel generation workers produce low-latency streaming responses.
