Make’s router is the more intuitive way to draw branches, but n8n wins complex conditional logic because of its code escape hatch and per-branch error handling. Here is the head-to-head and how to choose.
Build a monthly report that writes itself: schedule, pull data, compute the numbers in code, then let the model write prose around locked figures. The one rule that keeps the AI from inventing your metrics.
For a non-technical owner, the easiest automation tool is the one you can start from a template today. That is Zapier for most people. Here is why easy beats powerful, with a real first-automation story.
