Compare Carbon (Perplexity) and Chunkr side by side. Both are tools in the RAG Frameworks category.
Carbon, acquired by Perplexity in December 2024, provided pre-built data connectors for ingesting unstructured data from 25+ sources into LLM applications. Its managed API was wound down in March 2025, with its technology now integrated into Perplexity's enterprise data connectivity stack. Carbon's connectors supported Google Drive, Notion, Slack, Confluence, and other popular data sources for RAG pipelines.
Chunkr is a document parsing and chunking service optimized for RAG pipelines. It handles PDFs, images, tables, and complex document layouts, producing clean structured output ready for embedding and retrieval. Chunkr focuses on the critical pre-processing step that determines RAG quality.
Frameworks and tools for building retrieval-augmented generation pipelines—document parsing, chunking, indexing, and query engines that connect LLMs to your data.
