Draft an invoice from a sentence
“Invoice Acme for 3 days of consulting.” Hermes prepares the draft in your invoicing app — you review and send. It never sends on its own.
Hermes · your private AI agent
Your business has an assistant now.
Your data, your agent — not their cloud.
Hermes is a private AI agent that actually does the work: draft an invoice, file a contract, answer a question from your own documents. It lives on your own server, so nothing you tell it ever leaves your business.
What it does for you
Find anything you've ever filed
Ask a plain question and get an answer drawn from your own documents, invoices and notes — with its sources. Your files never leave the server to answer it.
Run your automations by asking
“Chase the overdue invoices.” Hermes triggers the right automation — the same reviewed, safe recipes already running on your server.
It remembers your business
Persistent memory means it learns how you work — your clients, your wording, your process — instead of starting from scratch every conversation.
Not another cloud chatbot
The difference: it's yours, and it stays on your server
No third-party AI cloud
On a Private AI plan the model runs on a ReefOffice GPU in Germany; on other plans you connect your own provider key. Either way, no third-party AI ever sees your data.
Your data trains no one
Your documents and questions are never used to train a model, and never pooled with other businesses. Proton's Lumo is private but still on their cloud; Copilot and Gemini scan your data. Hermes doesn't leave your box.
An agent, not just a chat
Chatbots answer questions. Hermes acts — across your real apps — then hands the result back to you to approve.
Never a hidden ReefOffice markup
ReefOffice never bills AI by usage. On a GPU plan, local AI is included at a flat rate, with no limit. With your own key (free Groq, OpenAI, Anthropic), you keep full control of that spend — and you can switch anytime.

Safe by design
An agent you can trust with your business
✓ It always asks first
Anything that creates or changes data — an invoice, a filing — is drafted for your review. Hermes never finalises or sends on your behalf.
✓ Open-source, auditable skills
The skills that define what Hermes can do are open-source and reviewed — published as ReefCoral under Apache-2.0. No black box.
✓ Governed self-learning
When it learns a new skill, every change is versioned, scanned and kept in your own Git — it can't quietly grant itself new powers.
✓ Every action is logged, never invisible
Every action Hermes takes is written to a tamper-evident audit trail (cryptographic hash chain) — you always know what was done, when, and by whom.
On every plan
Hermes ships with every ReefOffice plan. Private AI plans run the model on a ReefOffice GPU in Germany; Private Office plans connect your own AI key (Mistral, OpenAI, Claude…). Your agent, your choice of engine.

Hermes doesn't improvise your business logic — it triggers the same reviewed automations that run on your server. The agent is the voice; the automations are the hands.
