Hermes Desktop

What is Hermes Desktop?

Nous Research's desktop agent with persistent memory and skills.

Who is Hermes Desktop best for?

Hermes Desktop is best for people who want Nous Research's agent, with its long-term memory, in a desktop app.

• Hermes users who want an app

  It is the same agent as the command-line version, sharing config, keys, sessions, skills and memory, so a chat started in one picks up in the other.

• A long-running personal assistant

  Hermes remembers your projects across sessions and writes its own skills from past work, so it gets more useful the longer you run it.

• Mixed Mac, Windows and Linux setups

  It runs on macOS 12 or later, Windows 10 and 11, and any Linux distribution, where it installs from the terminal.

• People who customise their tools

  Plugins add tools, hooks, themes and integrations without changing the core, and the MIT license lets you change the code itself.

How much does Hermes Desktop cost?

Hermes Desktop is free and open source under the MIT license, and the optional Nous Portal plans that add hosted models, tools and cloud agents cost $20, $100 or $200 a month.

The app itself needs no plan or account. These are Nous Portal plans, which connect Hermes to hosted models, the Tool Gateway (web search, scraping, image generation, browser use and speech, each billed per use) and cloud hosting, all paid from one credit balance. Each paid plan comes with 10% more credits than its price, models are billed per million tokens at the rates listed on the Portal, and extra credits can be topped up from $10 to $200 at a time.
