Poysis

The infrastructure layer for domain-specific AI co-pilots.

Applied AI LLMs Retrieval TypeScript Python

Every AI product that helps a human make a better decision is built from the same handful of building blocks. Poysis names seven of them — the Empath, the Indexer, the Doctor, the Librarian, the Strategist, the Profiler, and the Researcher — and makes them composable by anyone.

Today those primitives are assembled by engineers. Poysis turns them into a palette a domain expert can arrange: a hair-care brand composes Empath + Indexer + Doctor and gets a concierge that understands porosity; a fashion retailer adds Profiler + Librarian and gets a stylist that remembers you. Same seven primitives, infinite configurations.

The bet is simple: no single player can build for every domain. The winners will be the domain experts who move fast with the right infrastructure behind them. Poysis is that infrastructure.

    Synthesis and Retrieval: From Transcript to Answer

    An engineering decisions record for a creator-knowledge bot — how a raw transcript becomes a grounded, time-linked answer through semantic chunking, over-fetch-and-gap retrieval, source diversification, and a code-enforced grounding contract.
