Sentinel understands what every message means.

The full message, the sender, the relationship, and the signals around it, not just keywords or a subject line.

Heuristics and reputation run first, language understanding handles the borderline cases, and relationship strength keeps real contacts safe.

Yes. Every score comes with a plain-language reason you can audit, explainable by design.

No. Sentinel is the understanding layer that works for Pax. You never operate it directly, you just get an assistant that reads everything first.

Pax is an AI executive assistant for individuals and a chief of staff to organizations. It reads what comes in, drafts and sends in your voice, runs your calendar, and remembers the context of your work and your life, taking real actions across the tools you already use.

Sentinel is one of the specialists behind Pax, the AI executive assistant. It works as a tool the assistant uses, not a separate product you operate.

A chatbot answers when prompted. Pax runs a continuous loop on its own, takes real actions across your tools, proves each step, and remembers how you work, which is what makes it an assistant rather than a feature.

Every plan includes Pax, with a seven day free trial you can cancel anytime. Connect your tools through secure sign-in and Sentinel is on the job from your first connected account.
