Retrieval-augmented generation pipelines built on fresh, indexed data.
How Tree-sitter Works: Parsing Code as You Type
Grammars, concrete syntax trees, GLR parsing, error recovery and queries, then how CocoIndex splits code into chunks on function and class boundaries.
Codebase Indexing for AI Agents with CocoIndex
Index a codebase for RAG and AI coding agents with CocoIndex V1 and Tree-sitter: language-aware chunking, embedding, and a live vector index in async Python.
Trace search results back to source data
Define query handlers in CocoIndex and trace search results back to source data in CocoInsight to close the loop on indexing strategy.
Search PDFs and Images Without OCR Using ColPali and Qdrant
Index PDFs and images into one Qdrant collection with CocoIndex v1 and ColPali multi-vector embeddings. Each page is embedded as an image, so no OCR is needed.
Extract Metadata from Research Paper PDFs with an LLM
Index academic papers with CocoIndex: read the first page of each PDF, extract title, authors, and abstract with an LLM, and embed them for semantic search.
What Are Text Embeddings? Build Semantic Search in Python
Text embeddings 101: what an embedding is, how similarity works, why you chunk, and how to build a semantic search index with CocoIndex v1 and pgvector.
CocoIndex Changelog 2025-03-20
First release of CocoIndex Changelog: LLM support, codebase indexing, custom functions, and assorted core/performance improvements
Build Real-Time Codebase Indexing for AI Code Generation
Indexing codebase for RAG with CocoIndex and Tree-sitter in real-time: chunking, embedding, semantic search, and build vector index for efficient retrieval.
We are officially open sourced! 🎉
CocoIndex is now open source: an engine that combines custom transformation logic with incremental processing for data indexing.
Customizable Data Indexing Pipelines
What customizable data indexing pipelines are and why custom transformation logic matters, with practical CocoIndex examples.
CocoIndex - A Data Indexing Platform for AI Applications
CocoIndex is a data indexing platform for AI: ingestion, chunking, embedding, and pipeline management for RAG, semantic search, and knowledge graphs.
