Frequently asked questions
What is the difference between an AI agent and a chatbot?
A chatbot mainly replies in chat. An agent can take actions: browse the web, fill forms, use connected apps, or run multi-step workflows. The picks above are listed because they do more than answer questions.
Is it safe to let an AI book things or use my accounts?
Treat agents like a new teammate with limited access. Prefer tools that ask for approval before purchases, sends or logins (Hark and Muse from Meta describe approval flows on their sites). Connect only the accounts you need, review actions before they finalize, and never share passwords in chat if a secure connector or vault is available.
Do I need to install anything to try an agent?
Not always. Manus and Zapier Agents run in the browser. Perplexity Comet is a downloadable AI browser (Mac, Windows, iOS, Android per its site). Hark has a web app plus iOS and Android. n8n can run in their cloud or on your own machine.
