David

David is distributed as a Chrome extension and targets a narrow, practical annoyance: filling in the same kinds of web forms again and again. Instead of typing your name, address, preferences and survey answers field by field, the extension detects the inputs on the page and completes them for you.

The publisher describes it as learning and adapting over time, so the more often you use it, the closer its fills get to what you would have typed yourself. Customisable settings give you control over how aggressive the automation is, which matters when a mistake on a checkout page is more costly than a mistake on a survey.

It is a small, single-purpose tool with a very modest install base and English-only interface. If your browser use involves a lot of registration and data-entry screens, it is worth a look; if you rarely touch web forms, there is little here for you.
