How to choose an AI agent
The right agent depends on the job and who's running it. For general autonomous tasks, Manus and Genspark act as do-everything agents; for software specifically, Devin is the autonomous 'AI engineer.' For business automation, Lindy and Relevance AI build agent teams for sales, support, and ops, while Gumloop, Bardeen, and Relay.app focus on no-code agentic workflows. Developers building custom agents reach for frameworks like CrewAI, and enterprises standardizing on a platform look at Agentforce (Salesforce). Cluely is a different animal — a real-time on-screen assistant.
Before you commit, weigh three things: how much supervision the agent needs (more autonomy means more speed but more risk), how it's priced (per-task, per-seat, or usage-based costs add up fast on frontier models), and what it can touch — an agent with access to your code, inbox, or CRM needs guardrails. Start narrow, keep a human in the loop on anything consequential, and expand once you trust it.
