Product Summary

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.

Product Summary

Vectara is a RAG-as-a-service platform that provides end-to-end retrieval-augmented generation through a single API. It handles document ingestion, chunking, embedding, retrieval, reranking, and generation—with built-in hallucination detection and citation extraction—without requiring developers to manage any RAG infrastructure.
