Introducing Harness

One assistant.
All of you.

Harness orchestrates your business and your life. Powered by two engines—Mnemos, the memory that never forgets, and Kratos, the will that keeps you sovereign. It grows with you. Learns from you. Your teacher, advisor, council, comrade, and assistant.

Meet Harness How it works

Two engines. One mind.
The brain that remembers. The will that protects.

Most AI assistants reset every conversation. Harness is built on two engines: Mnemos—the memory engine that never forgets, and Kratos—the decision engine that keeps you sovereign. Mnemos remembers your business strategy, your daughter's name, and which model handled last week's contract review best. Kratos routes every request, enforces privacy, and ensures your data never leaves your control.

Never forgets

Mnemos, the memory engine at Harness's core, remembers every conversation, decision, and preference. It builds a living model of you that grows richer with every interaction.

Routes to the best model

Every request is matched to the right AI model for the job. No single-model lock-in. Claude for deep analysis, local models for private matters. Harness picks the best tool.

Learns and grows with you

Harness doesn't just answer questions. It learns from your patterns, your feedback, your life. Every month it's better than the last. Every year it's indispensable.
