It's about to be 2026 and we're still stuck in the CLI era when it comes to chatbots. So, I created an open source library called Quint. Quint is a small React library that lets you build structured, deterministic interactions on top of LLMs. Instead of everything being raw text, you can define explicit choices where a click can reveal information, send structured input back to the model, or do both, with full control over where the output appears. Quint only manages state and behavior, not presentation. Therefore, you can fully customize the buttons and reveal UI through your own components and styles. The core idea is simple: separate what the model receives, what the user sees, and where that output is rendered. This makes things like MCQs, explanations, role-play branches, and localized UI expansion predictable instead of hacky. Quint doesn’t depend on any AI provider and works even without an LLM. All model interaction happens through callbacks, so you can plug in OpenAI, Gemini, Claude, or a mock function. It’s early (v0.1.0), but the core abstraction is stable. I’d love feedback on whether this is a useful direction or if there are obvious flaws I’m missing. This is just the start. Soon we'll have entire ui elements that can be rendered by LLMs making every interaction easy asf for the avg end user.
