FillApp▲14
I built a free Chrome extension called FillApp. It lets you fill web forms just by writing plain text like: “Ship it from @NorthDelivery to @WestflowLimited” It parses the form automatically and fills it with the right data, including tricky fields like dates, multiselects, etc. You can also save and reuse snippets across different forms. It’s completely free and works with most modern web forms. Would love to hear what you think.
