It connects to projects through an API key and is built to help teams craft prompts with clear targets and measurable outcomes. The project is publicly available for contributors and users on its GitHub page.
Main capabilities
- Generate and iterate new prompt candidates to expand idea variety
- Run evaluation "battles" that compare prompts and surface the most contextually appropriate options
- Let users define clear objectives and attach test cases to verify expected behavior
- Offer open-source code and documentation so developers can inspect, modify, or self-host
How to connect and use
The service is browser-based and requires an API key for integration into external tools or pipelines. Typical workflows include specifying the desired result, supplying sample inputs or tests, and letting the system produce, compare, and rank prompt variants. Results can be reviewed and refined iteratively.
