Profile

Hi HNI’ve been working on VizuLLM, an open-source engine that turns structured LLM outputs (JSON) into deterministic, printable documents like timetables, invoices, guides, and diagrams.LLMs are great at generating text, but in real applications we usually need documents, not paragraphs. VizuLLM introduces a strict contract between the model and the UI: • LLM generates schema-validated JSON • Schemas define a document type • VizuLLM renders a deterministic visual artifact (HTML / PDF)Instead of asking an LLM to “write a PDF”, you ask it to generate data for a document schema, and the renderer handles the rest.What makes it different: • Schema-driven (Zod) → predictable outputs • Renderer-fir

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

The company is listed at the Show HN launch stage of development.
