Operating in show hn launch, Nudge – A type-safe prompt builder with CLI codegen for AI apps operates.

Profile

We’ve been experimenting with a more controllable way of prompting, which led us to build Nudge - a better way to write type-safe prompts for TypeScript AI applications.Nudge lets you define prompts via a TypeScript builder API, then uses a CLI tool to generate the final system prompts. You describe intent structurally, not by tweaking wording, caps, or repetition. Instructions can be “nudged” with a numeric strength instead.Prompts support:- type-safe variables- optional blocks toggled at runtime- multiple variants for A/B testingBecause prompts are structured, parts are easy to reuse across agents. Prompts can also be tested and iteratively improved using an LLM based on failing test cases

The company sits in the show hn launch segment, where it competes on its core product or service.

Its current recorded stage is Show HN launch.
