Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
API requires Python-specific patterns, TypeScript SDK is community-maintained
v0.1 to v0.2 migration required rewriting chain definitions
Primary integration is with Google Drive, lacks support for other cloud storage solutions like AWS S3 or Dropbox
Indexing and searching through a large number of documents can be slow due to the reliance on GPT-3 API calls, which have rate limits
