I kept running into the same problem when using LLMs in real products. They are amazing at generating text, but unreliable when you actually need documents. Every time I asked an LLM to create something structured like an invoice, a manual, or a timeline, the result felt like a gamble. Layouts broke, formats drifted, and small prompt changes caused completely different outputs. That kind of unpredictability makes LLMs hard to trust in production and almost impossible to use in enterprise or branded workflows. VizuLLM came from a simple idea: LLMs should not design documents, they should generate content. By separating content as JSON from design as schemas and deterministic renderers, the luck factor is removed. The same input always produces the same output, which makes document generation predictable, repeatable, and safe for production use. I built VizuLLM to make AI-generated documents something you can actually rely on, customize, and ship with confidence. Making it open source was intentional. I want the community to help shape a standard for structured and deterministic AI outputs. Happy to hear your thoughts and feedback.
