Best context retrieval AI tools

Greb is an intelligent code search service that allows developers to find precise code chunks in massive codebases using natural language queries. It integrates seamlessly with AI coding assistants via MCP and offers a faster, more accurate alternative to traditional RAG systems.

Chonkie is an open-source data ingestion framework designed for AI applications. It efficiently cleans, chunks, and enriches various data sources like PDFs, code, and text, preparing optimized, context-ready data for Large Language Models to improve accuracy, reduce hallucinations, and enhance retrieval-augmented generation (RAG) systems.
