We make ApplyCandid, one of the tools below, so this page is not neutral and does not rank tools. What it gives you instead is a test you can run on any extension in ten minutes, and what each well-known tool says about itself on its own website, checked on 5 November 2026, with no figures taken from review blogs.
Short answer: the best free autofill extension is the one that passes the test on the kind of form you fill most. Watch most closely what it does with a question it does not recognize.
Five things to check before you install one
- Does the free tier fill real forms, indefinitely? Some free tiers are trials, and some cap how many jobs you can save or track rather than how many forms you can fill.
- What does it do with a field it does not recognize? Leaving it blank is safe. Filling it with a plausible guess is how a sponsorship or salary answer goes out wrong. 64.1% of employers ask about sponsorship on the form (study of 9,401 forms).
- Who clicks Submit? Autofill stops before Submit. Auto-apply submits for you. See autofill vs auto-apply.
- Does it ask for your LinkedIn, Indeed or Naukri password? A tool that works inside the tab you are signed into does not need it.
- Are AI answers based on your resume? A cover letter that reads well but describes a generic candidate is worse than none.
The 10-minute test
- Save your profile and resume in the extension.
- Open one real application form with a sponsorship question, a salary box and one written question. A Greenhouse or Workday form works. So does our practice form, which submits nothing.
- Run the autofill, then read every field before you touch anything.
- Count three things: fields filled correctly, fields left blank, and fields filled wrongly. The third number is the one that matters.
- Check whether anything was submitted or a button was clicked without you.
Run the same form through each tool you are considering. Ten minutes per tool tells you more than any ranking, this page included.
What each tool says it does
Quoted or summarized from each vendor's own website, checked on 5 November 2026. Prices and features change, so check the vendor's page before you decide. Where a vendor's page did not say something, the table says so rather than filling the gap from third-party reviews.
| Tool | What its own site says | Submits for you? |
|---|---|---|
| Simplify Copilot | “A free browser extension” that “autofills job applications on 100,000+ company career sites” and saves each application to your Simplify tracker | Not stated on the Copilot page |
| Huntr | A free Chrome extension; “You can autofill an unlimited number of job applications”. The first hundred jobs on its board are free, then $40 a month | Not stated |
| Jobright | “1-Click Application Autofill” across “all major ATS platforms”; the homepage gives no autofill price | Not stated |
| LazyApply | Will “automatically apply” to jobs on platforms including Greenhouse, Dice, Indeed and ZipRecruiter; plans of 15, 150 or 1,500 applications a day, billed yearly; no free tier for the automation | Yes (auto-apply) |
| ApplyCandid (ours) | Free tier with no end date: Easy Apply on LinkedIn, Indeed and Naukri, autofill on any career-site form, and 20 AI drafts a day. On career-site forms, unknown fields are left blank. Pro is $19 a month | Only LinkedIn Easy Apply and Naukri, only with auto-submit on (off by default, 15 a day); never on Indeed or company career sites |
Which kind fits you
- You want a free autofill extension with a large user base: Simplify Copilot is the best-known, and its own page says it is free. Run the test above on it.
- You want autofill tied to a job-tracking board: Huntr builds its autofill around a kanban tracker, with the 100-job limit on the free board.
- You want volume and accept the risks: auto-apply tools like LazyApply submit for you. Read what job sites' terms say first.
- You want blanks instead of guesses, Indian fields or Firefox: that is what ApplyCandid is built around. On company career-site forms it fills notice period and CTC exactly as you save them (how to answer those), works on Firefox, drafts Upwork proposals from your resume, and never asks for a portal password. It is newer, with a smaller user base than Simplify's.
Frequently asked questions
What is the best free Chrome extension to autofill job applications?
There is no single best one for everyone. Run the same awkward form, with a sponsorship question, a salary box and a written question, through each tool you are considering, and pick the one that fills the most fields correctly and fills none wrongly.
Is Simplify Copilot free?
Simplify's own Copilot page calls it a free browser extension that autofills applications on 100,000+ company career sites. Check Simplify's site for what its paid plan adds, as plans change.
Which autofill extension does not make up answers?
Test it directly: give it a form with a question your profile cannot answer and see whether it leaves the field blank. ApplyCandid leaves unrecognized fields blank on company career-site forms by design, and we publish ApplyCandid, so verify that claim the same way.
Do autofill extensions need my LinkedIn password?
They should not. Extensions that work inside the browser tab you are already signed into never need your password. Treat a tool that asks for it as a risk.
What is the difference between autofill and auto-apply extensions?
Autofill fills the form and leaves Submit to you. Auto-apply submits applications for you, often in bulk. Auto-apply is faster but sends answers you have not read and conflicts with some job sites' terms.
Test it on one awkward form.
ApplyCandid fills the factual fields from your saved profile, drafts the written ones from your real resume, and leaves anything it cannot identify blank.
