Simplify vs BestApply: Which Autofill Is Actually Better?
Both fill out job applications for you. But they fill them differently — and once you look at platform coverage, custom-question accuracy, and how much is left for you to finish, the gap gets real.

Simplify and BestApply both do the same headline thing: point them at a job application and they fill it in for you instead of making you retype your life story into another form. So the interesting question isn’t whether to use autofill — it’s whose autofill actually does the job better. Fill the standard fields but leave the custom questions blank, and you haven’t saved much. Fill a Greenhouse form flawlessly but choke on a Workday portal, and you’ve only covered half your search. The difference lives in the details.
Full disclosure up front: this runs on BestApply’s blog, so weigh the conclusion accordingly. But the specifics below are drawn from Simplify’s own documentation and public reviews, and Simplify is genuinely good — this isn’t a hit piece, it’s a look at where two autofill engines diverge.
What Simplify’s autofill gets right
Simplify’s Copilot extension is, deservedly, the most popular free autofill tool out there — more than a million installs and a rating near 4.9 on the Chrome Web Store. It reads your saved profile and populates application forms across the major applicant-tracking systems, and by most accounts it turns a fifteen-minute manual application into a roughly two-minute review. On modern platforms like Greenhouse and Lever, independent reviews put its fill accuracy around 90%, which is genuinely good for a free tool. The standard fields every form asks for — contact details, work history, education, work authorization — fill reliably, because those are consistent across systems. If your search runs mostly through clean, modern ATS forms and you just want the typing to disappear, Simplify does that well and costs nothing. That’s a real bar, and it clears it.
Where Simplify’s autofill starts leaving gaps
Three limits show up once you push past the standard fields, and they’re documented rather than hypothetical.
The first is the custom questions — the “why do you want to work here,” the short-answer prompts, the role-specific screeners. Simplify can save and reuse answers, but its matching keys on the exact question wording. Ask “Where do you see yourself in five years?” on one form and “Where do you see yourself down the road?” on the next, and it treats them as two different questions, leaving the second blank. To have those unique questions actually drafted for you, you need Simplify+, the paid tier at $39.99/month. On the free extension, the questions that most differentiate your application are largely still yours to write.
The second is tricky platforms. Accuracy that sits around 90% on Greenhouse and Lever reportedly slips on heavily customized Workday portals and older or government sites — exactly the forms where autofill would save the most time, because they’re the most tedious. Simplify officially names six platforms in its docs (Workday, Lever, Greenhouse, Ashby, iCIMS, Taleo) and supports many others through generic field-matching, which works well when a form is standard and less well when it isn’t.
The third isn’t Simplify’s fault so much as the category’s: no browser extension submits for you, and none can reach a posting behind a login wall or an invisible bot-detection layer. Simplify is explicit that you review and click Apply yourself. That’s a fair design choice — but it means the last mile, and the hardest sites, stay on your plate.
How BestApply’s autofill is built differently
BestApply approaches autofill from a different engineering angle, and it’s where the practical gap opens up.
Platform coverage is deeper, not just broad. Rather than relying mainly on generic field-matching, BestApply maintains dedicated, platform-specific autofill logic for around forty ATS platforms — Greenhouse, Lever, Ashby, Workday, iCIMS, Workable, SmartRecruiters, Oracle Cloud, Jobvite, BambooHR, Dice, Recruitee, Rippling, Teamtailor, and more. Each one is tuned to that platform’s actual field layout and quirks and tested against the live forms. Generic matching is what struggles on a customized Workday portal; a parser written specifically for that platform is what handles it. That’s the difference between “supports many sites” and “is built for this exact site.”
Custom questions get answered, not skipped. BestApply’s autofill spends what it calls AI answers to generate responses to the unique and screening questions on a form — and because it’s generating rather than matching saved text to exact wording, a reworded question doesn’t defeat it. The questions that Simplify’s free tier leaves blank, or that require the $39.99 upgrade to draft, are the ones BestApply is filling as part of the same pass. Fewer blanks left behind is both an accuracy win and a speed win, since the slowest part of any application is the writing, not the contact fields.
The hard sites don’t just stall. This is the piece pure autofill structurally can’t offer. When BestApply’s automation reaches a site built to stop scripts — an invisible CAPTCHA like the one Lever uses, a gated login, a form with strange branching logic — a human assistant takes over and completes it by hand. So the effective coverage isn’t “every form autofill can parse”; it’s that plus the forms autofill can’t. The philosophy behind that handoff is in AI applies, a human closes, and the broader mechanics of autofill are in what is application autofill.
Put those together and, on the autofill dimension specifically, BestApply covers more platforms with purpose-built accuracy, fills more of each form (the custom questions included), and doesn’t abandon the applications that block automation. On raw speed for a single standard form, both feel about the same — a click and a quick review — but BestApply leaves less for you to finish once that click is done.
The honest trade-offs
None of this makes Simplify a bad tool; it makes it a different one. Simplify is free, and its autofill keeps you in manual control of every submission, which some people specifically want. BestApply’s AI answers run on a daily quota rather than being unlimited-and-free (50 a day on the free plan; far more on paid tiers), and its deeper features — per-application resume and cover-letter tailoring into a template you select, with the layout kept intact — live on the paid plans (Pro and Max). With Simplify you review and submit each form yourself; with BestApply, an application review page shows exactly what was submitted on your behalf after the fact, and a human handles the gated sites — a different kind of oversight, not the same click-to-submit control. And if all you need is faster typing on standard forms that you’ll submit yourself, Simplify’s free extension is hard to argue with. See the pricing page for where BestApply’s lines are drawn.
The bottom line
If the question is narrowly “whose autofill fills more of my applications, more accurately, across more of the sites I’ll actually hit” — that’s the case BestApply is built to win, through platform-specific parsers, AI-answered custom questions, and a human who finishes what automation can’t. If the question is “what’s the best free way to stop retyping my contact details on standard forms,” Simplify remains an excellent answer. Match the tool to which of those you’re actually asking — and if it’s the first, try BestApply’s free plan and watch how much of each form comes back already done.
