About PromptC
Building the future of type-safe prompt engineering.
Our Mission
PromptC was born from a simple observation: as LLMs become more powerful, integrating them into reliable software systems remains surprisingly brittle. String manipulation and trial-and-error prompting are not scalable engineering practices.
We believe that prompt engineering should be treated as a discipline of software engineering, with the same tooling, safety guarantees, and reproducibility that we expect from traditional code.
Type Safety
End-to-end type safety from schema definition to LLM output using Zod.
Optimization
DSPy-style compilation optimizes prompts automatically for your specific metrics.
Infrastructure
Managed hosting, compiling, and testing for your prompts.
Open Source
The core of PromptC is open source and available on GitHub. We're committed to building in the public and supporting the broader ecosystem of LLM engineering tools.
