Frequently Asked Questions

What is the difference between an AI agent and workflow automation?

Workflow automation follows a fixed path you design step by step; an AI agent is given a goal and decides its own steps, using tools like email, search, and your apps. Agents handle ambiguous work (triage, research, outreach replies) that rigid workflows can't.

Which AI agent builder is easiest for non-technical users?

Lindy is the most approachable — you describe what the assistant should do in plain language and connect your accounts. Gumloop and Relevance AI expose more control through visual canvases, which suits ops and technical teams better.

How much do AI agent platforms cost?

Entry plans range from $19/month (Relevance AI) to $49.99/month (Lindy) and $97/month (Gumloop). All three bill by usage credits on top of the subscription, so estimate your monthly task volume before choosing.
