TapPass vs Arthur AI.

Arthur AI monitors model performance, bias, and explainability. TapPass governs AI agents at runtime, scanning and blocking in real-time before damage happens.

The difference

Monitoring vs. governance

Arthur AI: model monitoring

Arthur AI observes model performance, detects bias, provides explainability. The focus is understanding how models behave over time.

TapPass: interaction governance

TapPass governs every interaction. What data the agent sends, what tools it calls, what the response contains. Real-time scanning, blocking, auditing.

Blocking vs. observing

Arthur AI observes and reports. TapPass observes, reports, and blocks. When an agent sends PII, TapPass blocks the request before it reaches the model.

The point

Monitoring tells you what happened. Governance prevents it.

This comparison is about scope, not quality. Detection tools do detection well. TapPass is the layer that decides what an agent may do, holds the calls that need a person, and leaves a record you can hand to an auditor. If you already run Arthur AI, TapPass sits in front of it rather than replacing it.
