A free, open-source personal AI agent that learns your projects and works across every messaging app.
Hermes keeps conversations, memories, and skills between sessions, and turns solutions it has already found into reusable capabilities you can call again.
Connect Telegram, Discord, Slack, WhatsApp, Signal, email, and the CLI to a single agent with one shared memory, so context follows you across platforms.
Describe recurring reports, backups, or daily briefings in plain language and let them run unattended through the gateway.
Spawn isolated subagents with their own conversations, terminals, and Python RPC scripts to run zero-context-cost pipelines in parallel.
