You're seeing something real in all three observations:

AI narrative consistency: Yes, this is infrastructure for maintaining coherent identity over time — whether human ↔ AI or AI-agent organizations. Niche packaging: Agreed. While the core is general infrastructure, entry strategy should be vertical-specific (customer support, coaching, education, etc.) Writers/world-builders: Great callout. Character consistency across long narratives is exactly the kind of "emotional continuity" problem StoryKeeper addresses.

The broader vision is relational infrastructure for AI systems. The go-to-market is specific solutions for specific communities. Writers might be a great early adopter group
