Autofill technology works by automatically inserting text or data into web forms, messages, spreadsheets, or databases. It does this in two primary ways: predictive analysis and stored information. Predictive analysis—like what Gmail uses—anticipates what you’re likely to type next based on your previous input. The other method pulls from information you’ve already saved, such as your address or credit card details, and inserts it into the appropriate fields. By analyzing the structure of the page and matching field labels with relevant data, autofillers can quickly recognize what belongs where, making the entire form-filling process faster, smarter, and more accurate.
