PromptL is a templating language specifically designed for LLM prompting
Provides a human-readable syntax for defining LLM conversations with dynamic variable interpolation and model configuration, replacing verbose JSON structures. Built as a universal WASM module with RPC transport for cross-language support (JavaScript, Python, and any WASM-capable runtime). Compiles prompts containing control flow logic and templated variables into standardized message formats compatible with major LLM providers.
