Feature Highlights โ€ข Auto-suggestions in dropdowns as you start typing. โ€ข Autofill any field using your context menu. โ€ข Add, edit, remove, and reorder your data as you wish. โ€ข Organize your data in folders. โ€ข All data is stored locally in your browser storage. โ€ข Import/export your data to a file.

Why Use SimpleFill โ€ข On average, it takes 12 seconds to type out a name, email, and address. With SimpleFill, it takes a maximum of 3 seconds. โ€ข The default browser autofill isn't accurate most of the time, and browsers don't allow you to edit the saved information. โ€ข Without SimpleFill, you can't fill out forms using your right-click context menu, which is super handy. โ€ข The default browser autofill do not work with large blocks of text, such as emails.

Getting Started โ€ข It's quite simple (no pun intended) to use SimpleFill. โ€ข Install the extension by clicking the 'Add to Chrome' button. โ€ข Right-click on any input field and select SimpleFill > Add form data... โ€ข Enter your details and click on the "Add" button. โ€ข As you type in any input field, SimpleFill will automatically suggest relevant entries. Alternatively, right-click on an input field and select your saved data directly from the SimpleFill context menu to instantly fill the form.

  • Ask HN: What Are You Working On? (February 2025)

It's a PDF generation API with a template editor UI for setting up fields on PDF forms. It makes it easy to turn complex tax and immigration forms into simple type-safe APIs with strong validations.

  • So you want to modify the text of a PDF by hand
    Great post. I've spend a lot of time reading through the PDF specification over the last ~5 years while building DocSpring [1], and I still feel like I've barely scratched the surface. Qpdf is a great tool. One of my other favorites is RUPS [2], which really lets you dig into the structure of a PDF.
