- Works with any AI model, no lock-in
It learns. It remembers. It grows.
What is Hermes Agent?
An assistant with a memory. And ambition.
Hermes Agent is the self-improving AI agent built by Nous Research. It’s the only agent with a built-in learning loop: it creates skills from experience, improves them during use, searches its own past conversations, and builds a deepening model of who you are. You talk to it from the chat apps you already use, and it quietly becomes a better assistant every week.
It learns on the job
Complex task done? It writes itself a reusable skill so next time is faster.
It remembers you
Projects, preferences, past decisions. Conversations pick up where they left off.
It's yours
Open source, MIT licensed, works with any AI model. We just do the hosting chores.
What it can do
Hire it once. Watch it level up.
Lives where you do
Telegram, Discord, Slack, WhatsApp, Signal, email and more. One agent, one memory, every surface.
Learns on the job
After a complex task it writes itself a skill, then improves it with use. The more you delegate, the better it gets.
Never forgets
It searches its own past conversations and builds a deepening model of who you are across sessions.
Schedules itself
Ask in plain language for daily briefings, weekly reports or reminders. It runs them unattended.
Delegates like a manager
It spins up isolated subagents with their own conversations and terminals for bigger jobs.
Browses and creates
Web search, browser automation, vision, image generation and text-to-speech, all built in.
Self-host vs PlusAgents
You could run it yourself. You just don’t have to.
Hermes famously runs on a $5 VPS, if you enjoy setting up a VPS. If you’d rather just have the assistant, that’s us.

Hermes FAQ
Good questions. Learned answers.
Is Hermes Agent really free and open source?
Yes. Hermes Agent is MIT-licensed open source, built by Nous Research with a large community. The software costs nothing. PlusAgents charges only for hosting it: our free tier costs $0, and paid plans start at $19/mo for an always-on agent.
What makes Hermes different from other agents?
The learning loop. Hermes creates skills from experience, improves them during use, remembers what worked, and builds a model of who you are across sessions. Most agents start from zero every morning. Hermes shows up having learned from yesterday.
Hermes Agent or OpenClaw: which should I pick?
Both are excellent. OpenClaw is the most popular personal assistant with a huge plugin ecosystem. Hermes stands out if you want an agent that improves over time and remembers you deeply. The free tier makes it easy to try both and keep your favorite.
Which AI models does it use?
Any major provider. Hermes is model-agnostic: switch models with a single command, no configuration changes, no lock-in. Every PlusAgents plan includes monthly LLM credits so it works out of the box, and you can bring your own keys too.
Can I move to self-hosting later?
Anytime. Hermes Agent is open source and your data is yours. Export everything, run it on your own hardware, and cancel in one click. No lock-in, we just handle the server chores while you'd rather not.
