Build AI solutions with quality, confidence, and safety

The all-in-one AI monitoring and analytics platform

Integrating with your LLM of choice

LangWatch provides all-in-one tooling to improve and iterate on your current models, as well as mitigating risks such as jailbreaking, sensitive data leaks and hallucinations

Why LangWatch

Safety first

Guardrails are crucial in AI maintenance. LangWatch safeguards you and your business from exposing sensitive data, prompt injection and keeps your AI from going off the rails, avoiding unforeseen damage to your brand.

Maintaining quality

Understanding the behaviour of both AI and users can be challenging for businesses with integrated AI. Ensure accurate and appropriate responses by constantly maintaining quality through oversight.

Seamless shipping

Once built,  AI products can cause instability. Langwatch provides tooling to iterate.

How LangWatch
unlocks safety

Robust safeguards

LangWatch’s safety checks and guardrails prevent common AI issues including jailbreaking, exposing sensitive data, and off-topic conversations.

Analysis and improvement

Track conversion rates, output quality, user feedback and knowledge base gaps with real-time metrics — gain constant insights for continuous improvement.

Intelligent evaluation

Powerful  evaluation allows you to evaluate the performance of your RAG, new models and prompts, develop datasets for testing, and run experimental simulations on tailored builds.

Don't just take our
word for it

LangWatch has enabled me to detect unforeseen results in LLM-driven data pipelines during development and production stages. These valuable insights allow me to address potential problems before they become apparent to end-users.
