# Features — What Can a Personal AI Agent Do?
## What Is a Personal AI Agent?
Unlike a chatbot that only answers questions, a personal AI agent **acts**. It can browse the web, send emails, manage files, update databases, and do it all while you sleep.
## How OpenClaw Works
Three components: **Gateway** (runs on your machine, orchestrates everything) → **LLM** (the brain — Claude, GPT, etc., runs in the cloud) → **Messaging Channels** (Telegram, WhatsApp, Discord, Slack, iMessage).
## Key Features
- **Multi-channel**: Talk to your agent via any supported platform
- **Persistent memory**: Remembers past conversations and decisions
- **Tool use**: Web search, browser automation, file management, external APIs
- **Sub-agents**: Spawn smaller agents for parallel tasks
- **Cron jobs**: Scheduled recurring tasks
- **Skills system**: Modular capabilities that can be added or shared
- **Proactive behavior (Heartbeats)**: Agent checks things on its own and reaches out when needed
## Two Working Paradigms
1. **Spaceship Mode**: Agent has real resource access but requires your supervision at the computer. Maximum power, requires presence.
2. **Autonomous Teams Mode**: Agents in isolated sandbox, no sensitive access, communicate via Telegram. Fully autonomous 24/7, but limited resource access.
## Alternatives
- **Lindy**: Cloud-based, easy, $49+/mo
- **n8n + AI**: Workflow automation with AI layer
- **Custom GPTs**: Simple chatbots, limited capabilities
- **AutoGPT**: Experimental open-source
- **CrewAI**: Multi-agent dev framework
OpenClaw's advantage: runs locally, your data stays yours, powerful enough for daily real use.
