Company
Chatter
Dead simple LLM testing and iteration
We built Chatter as a platform for testing and iterating on large language models. It lets developers and companies run prompts across different LLMs, write test cases to evaluate the outputs, and collaborate on prompt chains and QA. Think of it like Postman but for LLMs, focused on making prompt iteration and testing repeatable and team-friendly.
We live in Philadelphia, PA and the company is based here. After YC we'll continue there for now.
Philly offers us the space and community we need, and we're already here. We haven't needed to relocate yet.
