Application Autofill Extension

Project Overview

2025 was a year in (SWE) AI that enabled us to turn our ideas into working code. I initially thought it would be difficult for models to make a Chrome extension for a niche use case for our shop but I was wrong. Claude Opus 4.5 delivered a completely working extension that would log the user details and categorize them into their respective fields to be used later.

Currently, this extension has two modes: The Collection Mode and the Insert Mode. In Collection Mode, the extension listens for the details to be collected as forms are being filled out on a website that requires a profile builder, such as when applying for jobs or sending admissions. You can also add the details of the applicant manually from the Options page. Their personal details, such as their first and last name mobile number, email address, their Date of Birth, temporary and permanent addresses, domicile information, alongside academic and professional information can be added manually or via importing a JSON or Excel file.

And then there is the Insert Mode. After you enable Autofill from the extension and pick the applicant, the extension neatly suggests the information based on what is being asked in that particular field. For example, if the form is asking about the father's name, the extension will intelligently populate the name of the father to be filled. You can press enter to accept its suggestion and arrow keys to see other suggestions. You can also search for an applicant's entry by searching through the appropriate keyword. For instance, searching "BS" will populate all the information regarding an applicant's BS degree, such as the name of the degree, the university the applicant was enrolled in, his CGPA, etc. The data of candidates can also be exported as an Excel and JSON file.

This extension will be very useful in saving time for the applicants who frequently apply for jobs and the shops that offer the services of applying for jobs, as their details will be readily available to be filled whenever they want and shopkeepers will be able to store multiple applicant profiles to be reused later for their reoccurant customers.
