Explain it simply

Hermes Agent is a free AI assistant that you install and run yourself. You can message it from apps like Telegram or Slack, and it remembers past work and saves reusable skills. Because you host it, you control it, and you also have to maintain it.

MIT-licensed and model-agnostic. Reach it from Telegram, Slack, WhatsApp, email and more; it keeps memory across sessions and saves reusable skills from completed work.

Draft support replies inside your helpdesk with a self-hosted agent

A small-business owner wired Hermes Agent into Front with a write-only token so it drafts replies for his team. The goal is 80% less email writing; it is still a work in progress.

How it went

It reads the thread and writes a draft, but he said looking up answers in their software was still unreliable and the project was way harder than expected. The 80% figure is his goal, not a result.

  • A short, self-reported update, quoted in a third-party review; we couldn't load the original post ourselves.
  • Hermes is not a helpdesk product: by default its messaging gateway rejects unknown users, and its memory is shared across chats on a profile.
  • Keeping it behind your team, drafting only, is the safe shape.

For each new thread in [helpdesk], read the whole conversation, then search [FAQ built from our last 500 sent replies] and [help docs].

Write a draft reply in our voice. If you can't find a supported answer, leave an internal note saying what's missing instead of guessing.

Never send. Drafts only.

Know before you start
