Plurai: Vibe-Training Tool for AI Agent Evaluation and Guardrails

Summary

Plurai is a Product Hunt listing for a tool that provides "vibe training" for AI agent reliability. Users describe desired agent behavior, and Plurai generates training data, validates it, and deploys a custom model quickly. It eliminates the need for labeled data, annotation pipelines, and prompt engineering. The system uses small language models offering sub-100ms latency, 8x lower cost than GPT-based evaluation, and over 43% fewer failures. It is built on published research (BARRED).
