Clawdbot is a revolutionary open-source AI assistant created by Peter Steinberger (@steipete) that runs entirely on your local machine. Unlike cloud-based AI assistants, Clawdbot prioritizes privacy by keeping all your data and conversations on your own hardware. The assistant connects to your favorite chat apps (WhatsApp, Telegram, Discord, Slack, Signal, iMessage) and can perform real-world tasks autonomously. It maintains persistent memory, learning your preferences over time, and can control your browser, manage files, execute shell commands, and integrate with 50+ services including Gmail, GitHub, Spotify, and smart home devices. What sets Clawdbot apart is its extensible skills framework - you can build custom plugins or use community-built ones from ClawdHub. The AI can even modify its own capabilities, write new skills, and handle background tasks via cron jobs. It supports multiple AI models including Claude (Anthropic), OpenAI GPT, and local models for complete privacy. Users describe experiencing "iPhone-moment" levels of innovation, with one stating "it genuinely feels like early AGI." The gap between what you can imagine and what Clawdbot can execute is remarkably small.
