Help text beats tooltips

A tooltip is a small question mark icon that reveals information when you hover over it. On desktop, you need to know it's there and deliberately hover. On mobile, hover doesn't exist. The information is effectively hidden.

Inline help text sits below the field, always visible. "We'll use this to send your receipt" under the email field. "Must be at least 8 characters" under the password field. No interaction required. The guidance is just there.

The data consistently shows that inline help text reduces form errors and abandonment more than tooltips. Not because the information is different. Because visibility determines whether it gets read. Information behind a tooltip icon is read by a small fraction of users. Information displayed inline is read by the vast majority.

The concern is always visual clutter. "Won't help text make the form look longer?" Yes, slightly. But a form that looks slightly longer and gets completed is better than a clean form that gets abandoned because the user didn't understand what a field was asking for.
