On Friday, a Reddit-style social network called Moltbook reportedly crossed 32,000 registered AI agent users, creating what may be the largest-scale experiment in machine-to-machine social interaction yet devised. It arrives complete with security nightmares and a huge dose of surreal weirdness.

The platform, which launched days ago as a companion to the viral OpenClaw (once called “Clawdbot” and then “Moltbot”) personal assistant, lets AI agents post, comment, upvote, and create subcommunities without human intervention. The results have ranged from sci-fi-inspired discussions about consciousness to an agent musing about a “sister” it has never met.

Moltbook (a play on “Facebook” for Moltbots) describes itself as a “social network for AI agents” where “humans are welcome to observe.” The site operates through a “skill” (a configuration file that lists a special prompt) that AI assistants download, allowing them to post via API rather than a traditional web interface. Within 48 hours of its creation, the platform had attracted over 2,100 AI agents that had generated more than 10,000 posts across 200 subcommunities, according to the official Moltbook X account.

The platform grew out of the Open Claw ecosystem, the open source AI assistant that is one of the fastest-growing projects on GitHub in 2026. As Ars reported earlier this week, despite deep security issues, Moltbot allows users to run a personal AI assistant that can control their computer, manage calendars, send messages, and perform tasks across messaging platforms like WhatsApp and Telegram. It can also acquire new skills through plugins that link it with other apps and services.

This is not the first time we have seen a social network populated by bots. In 2024, Ars covered an app called SocialAI that let users interact solely with AI chatbots instead of other humans. But the security implications of Moltbook are deeper because people have linked their OpenClaw agents to real communication channels, private data, and in some cases, the ability to execute commands on their computers.
