Hermes Agent

The agent that grows with you.

Overview

Hermes Agent is an open-source, self-improving AI agent built by Nous Research. It runs on your own infrastructure (desktop or server) under the MIT license, giving you full control and privacy. Unlike many cloud-based agents, Hermes Agent persists memory across sessions and learns from every interaction, automatically generating skills to become more helpful over time.

Core Features

• Multi-Platform Connectivity: Connects to Telegram, Discord, Slack, WhatsApp, Signal, Email, CLI, and more — all from one agent with unified memory.
• Persistent Memory: Remembers your projects, conversations, and preferences across sessions. It builds a knowledge graph of your activities, so it never forgets important context.
• Self-Improving Learning: A built-in learning loop analyzes past interactions to improve responses and generate new skills automatically.
• Open Source & MIT Licensed: Fully transparent and customizable. The codebase is publicly available and community-loved (218k+ GitHub stars) and implemented in Python.
• Desktop & Terminal Install: Quick install via one-liner package managers for macOS, Windows, and Linux, or grab the desktop app.
• Integration-Friendly: Works with popular dev tools like Claude Code, Codex, Gemini, Cursor, and OpenCode, making it a versatile hub for your AI workflow.

Use Cases

• Personal Assistant: Manage tasks across multiple chat platforms with a single, memory-capable agent that knows your context.
• Developer Companion: Pair Hermes Agent with code assistants to review PRs, debug issues, and answer questions using persistent project memory.
• Team Orchestration: Deploy in Slack or Discord to act as a team memory, summarizing discussions and automating repetitive Q&A.
• Learning Sandbox: Experiment with self-improving AI agents, customize skills, and extend functionality for research or hobby projects.
