I built Vampiro Life because I was frustrated with generic AI wrappers for tabletop RPGs. LLMs write great atmospheric prose, but they suffer from severe context amnesia—they constantly hallucinate inventory or lose track of mechanics (like "Hunger dice") after a few turns.

I realized that to make a campaign last, the chat transcript cannot be the source of truth.

I decoupled the narrative from the canonical game state using React SPA and Supabase:

State Backbone: Postgres stores character sheets, bounded NPC disposition scores, and world entities. AI output must pass through explicit state transitions (tool calls) to become canon.

Tiered Memory Rollups: To keep retrieval costs bounded, memory is compressed via Edge Functions into tiers (recent -> older -> ancient).

Deterministic NPCs: NPCs don't rely on the LLM "remembering" you. The system persists qualitative relationship edges (e.g., Rival, Sire) to the DB and injects them only when that NPC is in the scene.

There have been some interesting projects on Postgres.

The idea of this Extension (while exoteric) is to show the power of TLEs. You can even expand and play with things on hosted platforms like AWS and Supabase.
