Manus is a general-purpose AI agent that carries out tasks autonomously rather than only answering. It browses the web, writes and runs code in a cloud sandbox, builds slides, spreadsheets and websites, and connects to services through MCP connectors. It is for founders, analysts and knowledge workers who want to hand off research and production tasks. Manus runs tasks asynchronously in its own virtual machine, offers an API for developers, and has a free tier with daily credits plus paid plans.
