Arthur - AI/ML Monitoring & Observability Tool

Tool Icon

Arthur

A platform to monitor, evaluate and guard your AI systems from idea to production.

Founded by: Adam Wenchelin 2018

You can use Arthur when you’re deploying machine-learning or generative-AI systems and want them to perform reliably and safely. It offers continuous evaluation across the lifecycle, built-in guardrails to prevent unwanted behavior like hallucinations or data leakage, and dashboards to monitor model accuracy, drift and compliance. Ideal for teams that want visibility into their AI in production and fast detection of issues, rather than ad-hoc monitoring setups.

Use Cases

A fintech firm monitoring deployed credit-scoring models for drift and bias
A startup deploying conversational agents and enforcing guardrails for hallucinations and sensitive-data leakage
An enterprise auditing model performance across thousands of use-cases and generating dashboards for compliance teams
A data science team integrating model evaluation into their CI/CD pipeline and triggering alerts when metrics degrade

Tasks it helps with

Monitor model performance metrics (accuracy, drift, latency)
Evaluate generative-AI outputs for hallucinations, toxicity, prompt injection
Set up guardrails around acceptable use, PII detection and data leakage
Visualise and alert on agentic workflows and tool-selection behaviour
Aggregate logs, traces and metadata for ML/AI auditability
Integrate into CI/CD pipelines and trigger evaluations pre- and post-deployment

Who is it for?

Software Engineer, Data Scientist, Machine Learning Engineer, AI Research Scientist, DevOps Engineer, CTO, Compliance Manager, Risk Analyst, Product Manager
