Quick answer: The best autofill extension depends on where you apply. For simple startup forms most tools work. For Workday and other enterprise systems, where accuracy usually drops, you want one built for those custom fields that also drafts your screening answers and lets you review before submitting. This guide compares the main options honestly, including where each is weak.
Key takeaways
- Most autofill extensions handle simple forms well; the real difference shows up on Workday and enterprise ATS.
- The biggest time sink is screening questions, so a tool that only fills contact fields saves little.
- Review-first matters: a tool that auto-submits can send a wrong answer under your name.
- Free tools are great for basic use; check the paid tier terms before you commit.
- Pick for where you actually apply, not for the longest feature list.

What makes a good autofill extension?
Autofill extensions are easy to judge on the wrong thing. A long feature list does not matter if the tool cannot fill the forms you actually use. Judge them on four things:
- Does it handle enterprise ATS? Test it on a real Workday or iCIMS form, not just a simple contact page.
- Does it answer screening questions, or only fill name and email? The questions are where the time goes.
- Does it let you review before submitting? Auto-submit is a risk, not a feature.
- Is your data handled sensibly? You are trusting it with personal details.
Honest comparison of the main options
Every tool here has real strengths. This table is about fit, including where each one is weaker, so you can choose for your situation.
| Extension | Best for | Watch out for |
|---|---|---|
| Simplify | A free, popular all-rounder with a tracker | Accuracy drops on Workday and other enterprise forms; paid tier billing is often criticized |
| Huntr | People who want a strong job tracker plus autofill | Best features sit behind a higher-priced plan |
| SpeedyApply | Simple, fast basic autofill | Lighter on custom screening questions and enterprise ATS |
| JobWizard | Greenhouse-style forms | Coverage varies across other systems |
| VeloApply | Reliability on Workday and hard enterprise forms, plus drafting answers to screening questions, review-first | Newer, so fewer reviews than the older names |
The pattern across the category is consistent. The popular free tools are excellent for simple forms and job tracking, and they get weaker on the enterprise systems that large employers actually use. That gap is the main reason to consider a tool built specifically for those harder forms.
Which one works best on Workday?
Workday is where most autofill tools struggle, because it renders fields as custom components rather than simple boxes. If you apply to large employers, Workday reliability should be your deciding factor. This is the exact problem VeloApply is built around: it fills Workday work history, education, dates and custom dropdowns, and drafts answers to the screening questions, then highlights everything for you to review before you submit.
What to check on privacy
Whatever you choose, you are handing over your resume and personal details, so read the privacy policy. Check what data is stored, whether it is ever sold, and whether the tool can submit on your behalf. A review-first tool that never auto-submits keeps you in control. We cover this in more depth in our guide on whether AI job tools are safe with your data.
