There isn't one right way to apply to jobs, but the three common approaches trade off very differently, and it's worth being honest about what each one is actually good at.
Doing It Yourself
Filling out every field by hand, on the company's own careers page or whatever ATS it uses.
Where it wins: total control. Every word is one you chose, every answer is tailored exactly as much as you want it to be, and there's no tool in the loop that could mis-fill something or flag the wrong thing.
Where it costs you: the same twenty-odd fields, retyped from scratch on every single posting. Name, email, phone, work authorization, and then usually at least one open-ended question you're starting from a blank box on, every time. It's not that any single application is hard, it's that the repetition adds up over a real search. See What 10 Job Applications Actually Cost You in Time for the actual arithmetic on that.
LinkedIn Easy Apply
LinkedIn's one-click apply flow, built into postings hosted on LinkedIn itself.
Where it wins: speed, when it's available. For a posting that supports it, a full profile on LinkedIn can turn into a submitted application in a couple of clicks, no retyping at all.
Where it costs you: it only works on LinkedIn-hosted postings, which is a meaningful chunk of the market but far from all of it, most companies still run applications through Greenhouse, Lever, Workday, or their own careers page directly. It also pulls from one static LinkedIn profile rather than adapting per posting, so open-ended questions still land on you cold, and there's no per-field review step flagging what it filled versus what it couldn't.
UnlockRole
A saved profile plus a browser extension that fills applications wherever they actually live.
Where it wins: breadth and honesty about its own limits. It works across the ATS platforms that host most real postings (Greenhouse, Lever, Ashby, Workable, Workday, and more), not just one site, and it tells you explicitly what it couldn't fill rather than leaving a field looking done when it isn't. Open-ended questions get an AI-drafted answer grounded in your resume and the specific posting you're looking at, which is a real first draft to edit rather than a blank box, but it's never submitted without your review. See The Ethics of AI in Job Applications for exactly where those review boundaries sit.
Where it costs you: it's a browser extension you have to install and connect to a profile first, and like any tool working against arbitrary third-party forms, it won't be flawless on every single site, it flags what it's unsure about rather than guessing silently, which means you still do a final pass before submitting.
How to Actually Decide
These aren't mutually exclusive. A realistic setup for most people: use UnlockRole for the repetitive parts across the ATS platforms most postings actually use, use Easy Apply when a posting happens to support it and speed is what matters most, and do it fully by hand for the handful of applications, a dream role, an unusually specific cover letter request, where you want every word to be entirely your own with no assistance at all.
The wrong question is "which one tool should handle my whole search." The right one is "which approach fits this specific application," and that answer changes posting to posting.
