Hermes is already very powerful but with extensions, you can do a whole lot more with it. With Hermes Browse Extension, you can connect web content to your local or remote Hermes instance. It can use models, tools, skills, and everything you have worked on with Hermes. By default, it connects locally but it can connect to a remote Hermes API server. Voice dictation is supported through local audio. You get light, dark, sand system colors to choose from plus a bunch of themes.
