Perplexity AI vs ContextCh.at

Perplexity AI Overview

Perplexity AI is a conversational AI search engine that provides answers with citations from web sources. It allows users to upload files, links, and text to create a context for discussions and builds a knowledge graph from this data.

ContextCh.at is designed for in-depth interaction with *your private and specific content collections*, organized into distinct projects with persistent context and multiple chat sessions. While Perplexity AI allows uploads, ContextCh.at offers more robust management for proprietary knowledge bases.
