KittyHome vs Simplify, Jobright and LazyApply: job application autofill compared

The short answer

Competitors' plans are as listed on their sites or widely reported in October 2026. They change often, so check before you buy.

Accuracy: the right answer in every field

Filling a box is easy. Filling it with the right answer is the hard part, because every careers site words its questions differently and builds its own drop-downs. This is where KittyHome puts its effort:

• Questions that depend on the country. Work authorization and sponsorship have a row per country in your profile, so "Are you authorized to work in Canada?" and "…in the UK?" each get the right answer. A question that names two countries ("Will you be based in the U.S. or Canada?") is checked against both.
• Questions worked out from your profile. "Do you have at least 5 years of experience with Python?" gets a yes or no from your work history, not a number pasted into the wrong kind of field. Salary has a row per currency.
• Sites' own drop-downs and pickers. It opens them and searches like a person would: "UK" also tries "United Kingdom", and a phone country picker that only shows "+1" is matched to your country by its dialing code.
• It checks that each answer took. Some sites quietly reset a field after it's filled. After filling, it checks every field kept its value and tells you which ones didn't.
• When it isn't sure, it leaves the field for you and lists it in the panel. Show it on the page scrolls to each one and spotlights it. A blank field you can see is better than a confident wrong answer.
• What only you should answer stays yours: voluntary self-identification (gender, ethnicity, disability, veteran status) and questions like "Are you a U.S. citizen?" are never filled for you.
• It learns your corrections. Change an answer after a fill and it offers to remember it for next time. Nothing is saved until you press Remember.
• Problems get fixed. If a field goes wrong, Something's wrong? sends us the form's structure (never what you typed, unless you tick it), and you see the report before it's sent.

What it can fill

• Every kind of field: text boxes, lists, radio buttons, checkbox groups, dates, months, sites' custom drop-downs and searchable pickers, and phone numbers with their country.
• Your résumé and cover letter, attached to the upload fields that ask for them.
• Forms inside frames, such as a job board embedded in a company's own careers page, and forms with several steps.
• Open questions with Smart fill: "Why do you want to work here?" is drafted from the job posting on the page and the work, education and skills in your profile (never your contact details), in the question's own word or character limit.
• Tuned support for Greenhouse, Lever, Ashby, Jobvite and Workable, the systems behind most tech job postings, and ordinary forms on any other site.
• Everything around the application: the same extension writes your recruiter emails, LinkedIn messages and follow-ups with Alt+K, reading the thread you're answering. See how its writing compares.

Simplify

Simplify Copilot is a free extension that fills applications on a very large number of career sites and logs each one in a job tracker. Simplify also suggests jobs that match your profile. Simplify+ adds AI résumé tailoring, cover letters and answers to open questions.

• Pros: free unlimited autofill; a built-in tracker for everything you applied to; job matches; a large, well-known product.
• Cons: the AI answers for open questions are part of the paid plan, reported at $39.99 a month; it's a job-search tool only, so emails and messages to recruiters are written elsewhere.

Jobright

Jobright is first a job-matching service: it recommends jobs and scores how well you fit them. Its extension fills applications and can help with answers.

• Pros: good job recommendations; résumé and fit scoring; useful when you're still deciding where to apply.
• Cons: the free plan allows only a few autofills a day; the paid plan is reported at $39.99 a month with no public pricing page; like Simplify, it doesn't help with the rest of your writing.

LazyApply

LazyApply goes the other way: it applies to many jobs automatically on job boards, up to hundreds a day on its bigger plans.

• Pros: the most applications for the least time; useful if volume is all you need.
• Cons: you don't read each answer before it reaches the employer, so a wrong visa, salary or experience answer goes out with your name on it; generic answers stand out to recruiters; no free plan; yearly billing only.

Why KittyHome never submits for you

Recruiters read applications one at a time, and a careless answer is easy to spot. An extension that fills the form in seconds already saves you nearly all the time an application takes; the last minute, reading it over and pressing Submit, is what keeps every answer right. That's why KittyHome always stops before Submit.

Where KittyHome is ahead

1. 1Accuracy first: per-country answers, answers worked out from your profile, a check that each field took, and nothing guessed.
2. 2AI answers on the free plan: 5 Smart fills a day, with open questions drafted from the posting. Plain Fill from your profile has no limit on any plan.
3. 3You stay in control: a panel shows what goes where before anything is filled, and it never submits.
4. 4Private by default: your profile stays in your browser unless you choose to sync an encrypted copy.
5. 5More than applications: one extension also writes your emails, messages and posts.

Where KittyHome is behind

• No job tracker and no job recommendations. Simplify and Jobright have both.
• No bulk applying. If you want hundreds of applications a day, it isn't built for that.
• Tuned support for five application systems. Workday-style forms work, but Workday has no tuned support yet; anything it can't fill is listed for you.
• Chrome on a computer only.
• Smart fill has a daily limit (5 on Free, 25 on Pro, 75 on Ultimate). Plain Fill doesn't.
