How do I connect Google Docs to ChatNexus?
ChatNexus uses Google's OAuth flow, so you grant permission securely without sharing your password. You can select individual docs or entire folders. After authorization, the sync starts automatically on your chosen schedule (daily, weekly, etc.).
What happens to my Google Docs after I sync them?
The chunking process preserves context by overlapping segments—the last 150 characters of one chunk are the first 150 characters of the next. This helps the vector search find relevant information across chunk boundaries. The docs themselves are never modified.
How often are my Google Docs synced?
When you update a Google Doc, ChatNexus detects the change and re-chunks only the modified sections. Old embeddings are replaced with new ones. This keeps your knowledge base fresh without re-processing the entire doc every time.
What data storage backend does ChatNexus use?
Neon provides auto-scaling and serverless PostgreSQL. The pgvector extension enables semantic search via cosine similarity on your embeddings. All data is encrypted at rest and in transit.
Can I sync multiple Google Docs or folders?
When the user asks a question, ChatNexus searches across all synced documents, retrieves the top 3 most relevant chunks, and injects them into the system prompt. This is called Retrieval-Augmented Generation (RAG) and ensures accurate, sourced answers.
