David

David is a small Chrome extension that fills in web forms for you. It reads the fields on a registration, survey or checkout page and populates them using what it has learned about your preferences, so repetitive data entry takes seconds instead of minutes.

Automatic field completion

Detects form fields on the page and populates them automatically rather than making you tab through and type each one.

Preference learning

The extension adapts to your preferences and typical answers, so repeated fills need less correction.

Customisable behaviour

Settings let you decide how much the extension does on its own versus how much you review before submitting.

Works across registrations and surveys

Covers registrations, surveys, checkouts and other multi-field web forms rather than one specific site.
