Manus is a general purpose AI agent. Users give it a goal, and it breaks the job into steps, browses the web, writes and runs code and returns a finished result. It was made by the startup Butterfly Effect, the team behind the Monica browser assistant, and launched in March 2025.
Manus works inside its own virtual computer, so users can watch it open pages, fill in data and create files. Common tasks include research reports, data analysis, slide decks and simple websites. It uses models from other companies, such as Anthropic, along with its own tools. The company moved its headquarters to Singapore in 2025. Users can share a finished task as a replay so others can see each step.
Users get a small number of free credits. Paid plans give more monthly credits and let several tasks run at once. More complex tasks use more credits. Analysts, marketers, founders and researchers use it for work that would take many manual steps.
