What Is OpenClaw?

Last updated: February 4, 2026

OpenClaw is an open-source, self-hosted AI assistant designed to work like a full-time executive assistant — triaging email, managing calendars, drafting replies, sending messages, and automating workflows across your tools.

Unlike ChatGPT or Claude Desktop, OpenClaw isn't a chat window you open when you need something. It's an always-on agent that works in the background — checking your inbox, scheduling meetings, and taking action without you asking.

Origin & background

OpenClaw was created by Peter Steinberger, founder of PSPDFKit (now Nutrient), who scaled the company to $100M+ ARR with 250+ employees. He built a personal AI assistant for himself, then open-sourced it.

Originally called Clawdbot, then Moltbot, it was renamed to OpenClaw. The project has earned 150,000+ GitHub stars and is one of the fastest-growing open-source projects.

Security considerations

Running an AI agent with access to your email and calendar is inherently sensitive. This isn't a risk-free tool.

Research from Cisco identified susceptibility to prompt injection attacks through malicious email content. Proper deployment includes:

  • Audit trails for action review
  • Access controls limiting agent capabilities
  • Network isolation restricting system reach
  • Regular security patches

Professional deployment is recommended for proper security configuration.

Recognition & press

Featured in MacStories, Fast Company, and CNBC. Covered by IBM's research team. Active GitHub and Discord communities with regular releases.

“The most impressive open-source AI agent project.”

Who it's for

Founders and executives

Chiefs of staff
