About Carbon (Perplexity)
Carbon is a RAG (Retrieval-Augmented Generation) framework that helps developers connect external data sources to Large Language Models. The platform provides pre-built connectors to ingest unstructured data from any source and load it into any destination, with AI-ready data processing that chunks, embeds, and cleans content for optimal LLM performance. Carbon was designed to simplify building RAG applications with features including credentials and content encryption at rest and in transit, full SOC 2 Type II compliance, and advanced data processing capabilities. In December 2024, Carbon was acquired by Perplexity AI to enhance their enterprise search capabilities, allowing users to search through files and work messages in Notion, Google Docs, Slack, and other enterprise applications.
