⏱️ The 60-Second Summary

✅ Perfect for:

•RAG applications requiring entity relationship understanding where "who worked with whom" or "which companies invested in what" matters more than text similarity
•Legal document analysis systems that need to track relationships between cases, parties, and regulations across large document collections
•Financial research platforms analyzing connections between companies, investors, executives, and market events from diverse data sources

❌ Skip it if:

•You knowledge graph quality depends heavily on input data quality and extraction model accuracy, requiring careful tuning for specialized domains
•You neo4j infrastructure adds operational complexity compared to vector-only solutions that just need embedding storage
•You graph construction and queries are slower than simple vector retrieval, particularly for large document collections

💰 Bottom line: Free gets you ai tool — details coming soon
