Perplexity acquires Carbon to connect AI search to your work files

Perplexity acquired a small Seattle-based startup called Carbon which specializes in connecting AI systems to external data sources, the companies announced on Wednesday. CEO Aravind Srinivasan says this will allow Perplexity to search through your files and work messages in Notion, Google Docs, Slack, and other enterprise applications sometime in early 2025.

Carbon specializes in retrieval augmented generation, or RAG, which allows large language models to access information from external databases before it generates an answer. By bringing Carbon’s technology and staff on board, Perplexity could be opening the door to launching enterprise search products. These tools connect generative AI to enterprise databases, allowing employees to quickly search through the mass of unstructured data their companies have acquired over the years.

This is Perplexity’s second acquisition, following its 2023 acquisition of Spellwise, whose CEO was brought on to develop Perplexity’s mobile app.
