Is HermesMarkdown the same as Hermes Agent?

No. HermesMarkdown is a browser-based Markdown editor. Hermes Agent is a separate AI agent project that uses files like SOUL.md and memory.md. They share a name and nothing else — here's the actual difference.

HermesMarkdown, in one sentence

HermesMarkdown is a Markdown editor that runs entirely in your browser. There's no account and no upload step. Your notes live in a vault, and you choose where: a folder of .md files on your disk, edited in place (Chrome, Edge, and other Chromium browsers; an existing Obsidian vault works too), a browser vault kept in the browser's own storage (any browser, including Safari, Firefox, phones, and tablets), or a GitHub repository when you want the same notes on several devices. Installed as an app, it works offline. Only GitHub sync and the optional bring-your-own-key AI features talk to a server. It has no relationship to any AI agent's memory system.

What Hermes Agent's markdown files are

Hermes Agent (from NousResearch) is an unrelated AI agent project. It stores agent memory, personas, and plans in specific markdown files:

  • SOUL.md — custom personality/behavior definitions for the agent
  • memory.md — persistent memory and context the agent stores across sessions
  • Plan-mode markdown files — structured goals, assumptions, and steps the agent generates before executing changes
  • hermes.md / .hermes.md — project-context filenames used by Hermes Agent and compatible tools, similar in purpose to AGENTS.md or CLAUDE.md

None of these are created, read, or required by HermesMarkdown. HermesMarkdown doesn't define special filenames at all — it edits whatever Markdown already exists in the folder you open, whether that's an Obsidian vault, a docs folder, or a plain notes directory.

NoteHermes Agent (NousResearch) and HermesMarkdown are unrelated projects that happen to share the Hermes name. If you landed here looking for SOUL.md, memory.md, or plan-mode setup, this isn't that — you likely want Hermes Agent's own documentation.

If you're looking for agent-readable notes

HermesMarkdown doesn't generate agent memory or context files. Your vault is plain Markdown, so any AI tool that reads files can read it as-is — and you can keep your own AGENTS.md or CLAUDE.md in the vault and edit it like any other note.

  • Frontmatter such as title and tags stays in each file, where agents can skim it without opening every note body.
  • Dotfiles and _-prefixed files (for example agent skill files) can be shown in Files with the Show Hidden Files setting.

See Frontmatter conventions in the documentation for details.
