01. What Is Hermes?

An open-source AI agent that lives on your machine and actually does the work.

Every AI tool you use in a temporary thread starts with a context problem. Hermes is built around persistence. It is an open-source agent that runs on your machine or server, takes real action through tools, and reports back through the terminal, desktop or a messaging gateway spanning 21+ platforms when native and plugin channels are counted together.

The difference from a normal AI assistant is agency. A chatbot answers a question and forgets you. Hermes holds context about you, your business, and your family, then runs recurring work on a schedule without being asked. Think of it less as a tool and more as a chief of staff that never sleeps.

Everything in this playbook is a real, running Hermes setup. At Ential it shows up as Donna: the assistant that runs the morning brief, triages the pipeline, plans date night, and keeps the books honest. By the end you will have the same operating pattern on infrastructure you choose.

"Your agent. Your machine. Your rules. Your choice of model provider."

  • Runs 24/7 on your own computer or a server
  • Connects to email, calendar, CRM, project tools, and messaging apps
  • Runs recurring jobs on a schedule (briefs, reviews, reminders)
  • Supports subscriptions, API providers and local open models
  • Self-hosted runtime. Model and connector choices still determine where data goes
  • Extensible with skills for anything you do more than once
