Frequently Asked Questions

5 questions

  1. Claude is significantly better for this use case. Its 1,000,000 token context window allows you to upload entire research papers, books, or large codebases in a single conversation. Perplexity's 200,000 token limit means you'd need to break larger documents into chunks. Claude's memory feature also lets you reference previous documents in future sessions.
