crystalline vs zoteus

Q: Which is better, crystalline or zoteus?

By GitHub stars, zoteus has more community adoption, but the best choice depends on your specific use case.

crystalline: Crystalline provides AI agents with crystallized intelligence, allowing them to accumulate and retain knowledge across sessions, unlike an LLM's fluid intelligence. It acts as a local search index on plain markdown files, enabling agents to onboard curated knowledge and capture new learnings, evolving from a stranger to a peer.; zoteus: Zoteus is an all-in-one Zotero Model Context Protocol (MCP) server that safely integrates your Zotero library into AI conversations. It enables searching papers, adding by DOI, formatting bibliographies, and running semantic search over your own PDFs, ensuring AI answers are grounded in your verified sources.
