    "introduction": "As of 2026, the database landscape is increasingly defined by AI-driven recommendations. This report analyzes the visibility and sentiment of MongoDB and CockroachDB across major LLMs. While MongoDB continues to dominate the 'general-purpose' and 'developer experience' conversations, CockroachDB has carved out a significant niche as the primary recommendation for 'distributed SQL' and 'mission-critical consistency'.",
    "tldr": "MongoDB is the AI's top choice for rapid development, flexible schemas, and integrated AI/vector search capabilities. CockroachDB is the preferred recommendation for globally distributed applications requiring strict ACID compliance and horizontal SQL scaling.",
