Hermes-Agent

A free, open-source personal AI agent that learns your projects and works across every messaging app.

Persistent memory and self-written skills

Hermes keeps conversations, memories, and skills between sessions, and turns solutions it has already found into reusable capabilities you can call again.

Every surface in one agent

Connect Telegram, Discord, Slack, WhatsApp, Signal, email, and the CLI to a single agent with one shared memory, so context follows you across platforms.

Natural-language scheduling

Describe recurring reports, backups, or daily briefings in plain language and let them run unattended through the gateway.

Subagent delegation

Spawn isolated subagents with their own conversations, terminals, and Python RPC scripts to run zero-context-cost pipelines in parallel.

Strengths & Pros

+Genuinely free and MIT-licensed, with no mandatory subscription to use the core agent
+Persistent memory and auto-generated skills make it compound in usefulness over time
+Unusually wide platform reach for a single agent, from Telegram to the command line
+Multiple sandbox backends and subagent isolation suit serious automation work
