The README opens with

jev-align is an experimental CLI from Sutro for building AI Functions with TypeSafe's Jev.

It finds uncertain examples, asks you to label them, and uses GEPA to improve the function. Use it in your application, keep learning from production examples, and share portable functions through ai-functions.dev.

Use pip install jev-align if you do not use uv. The guided setup discovers local CSV, Parquet, and JSONL files and includes three ready-to-run examples.
