Manus
★ 4.2 / 5
Butterfly Effect AI
Manus launched in early 2025 with viral demos showing an AI agent that could complete hours-long tasks autonomously — researching, writing, coding, and deploying without constant supervision. A year later, does it live up to the hype?

Frequently asked questions about AI agents

What's the best AI agent in 2026?
Manus leads for general-purpose agentic work. Devin leads for autonomous coding. Claude Computer Use leads for browser-driven automation. Capability varies meaningfully by task — try the free tier on your specific automation use case.
Can AI agents replace virtual assistants?
For specific repetitive tasks (booking, research, data entry) — increasingly yes. For nuanced judgment work, communication, and relationship management — no, human assistants still win.
Are AI agents safe to give credentials to?
High caution. Agents that operate browsers and applications on your behalf can take actions you didn't intend. Use isolated browser profiles, scope credentials narrowly, and review action logs. Don't give agents access to financial accounts or anything irreversible.
