local-deep-researchBenchmark45/100 via “multi-source iterative research with llm-driven query refinement”
Local Deep Research achieves ~95% on SimpleQA benchmark (tested with GPT-4.1-mini). Supports local and cloud LLMs (Ollama, Google, Anthropic, ...). Searches 10+ sources - arXiv, PubMed, web, and your private documents. Everything Local & Encrypted.
Unique: Implements LLM-driven query refinement loop where each research iteration analyzes gaps in current results and reformulates queries, rather than executing a static search plan. This is coordinated through a Research Service that manages execution lifecycle with thread-safe context management, enabling concurrent research tasks with per-user isolation via SQLCipher encrypted databases.
vs others: Outperforms single-pass research tools (Perplexity, traditional RAG) by iteratively deepening search based on LLM reasoning about gaps, achieving ~95% accuracy on SimpleQA benchmark while maintaining full local deployment and encryption for sensitive research.
