Manus is an autonomous AI agent platform that can independently complete complex multi-step tasks by browsing the web, writing code, managing files, and using computer interfaces. HQ: Shanghai.
Manus is an autonomous AI agent developed by Monica (a Chinese AI company), designed to complete complex multi-step tasks independently using a combination of web browsing, code execution, file management, and computer interface interaction. Unlike AI chatbots that answer questions, Manus takes actions: given a research task, it can search multiple sources, synthesize findings, generate reports, and save the results — all without step-by-step human guidance. The system uses a "computer use" approach where the AI can operate software interfaces as a human would, making it capable of tasks across virtually any domain.
