NVIDIA-NeMo/Guardrails
NeMo Guardrails is an open-source toolkit for easily adding programmable guardrails to LLM-based conversational systems.
This toolkit helps you control what your AI chatbots say and do. It lets you set specific rules, like preventing discussions on certain topics or guiding the conversation down a predefined path. You give it your AI's input and rules, and it ensures the AI's responses are safe, on-topic, and consistent. This is for developers building conversational AI applications for customers or internal users.
5,772 stars. Actively maintained with 9 commits in the last 30 days.
Use this if you are building an AI chatbot or assistant and need to ensure it behaves predictably, stays on brand, avoids inappropriate content, or follows specific conversation flows.
Not ideal if you are looking for a pre-built, ready-to-deploy chatbot solution without needing to define custom rules or integrate with existing LLM applications.
