Simplify vs LazyApply vs JobRizzer: Which Autofill Wins?

If you want the short version: Simplify is the best free pure-autofill extension, LazyApply is a bulk auto-apply tool that submits for you (with the quality risks that implies), and JobRizzer sits in the middle as assisted autofill plus per-job resume tailoring. The right pick depends on whether you value control and quality or raw volume.

All three live in your browser and promise to kill the tedium of retyping the same details into every application form. But they take very different bets on how much the tool should do for you. That difference matters more than any feature checklist.

The core difference: assisted vs auto-apply

The single most important question is whether a tool submits applications on your behalf.

• Simplify is assisted. It autofills fields across ATS platforms; you review and submit. It does not blast out applications.
• LazyApply is auto-apply. You set filters, and it submits to large batches of jobs automatically, often hundreds in a session.
• JobRizzer is assisted by design. It fills the form and (on Pro) tailors your resume, but you review every field and submit yourself. No auto-submit, no bots.

Auto-apply sounds like a dream when you're exhausted, but the reported downside is consistent: generic submissions, wrong answers to screening questions, and applications sent to roles you'd never actually take. A few hundred low-quality applications rarely beat 20 careful ones. For the honest breakdown, see our Is LazyApply legit review.

Autofill quality and coverage

Coverage is where these tools either earn their keep or quietly fail you mid-application.

Simplify is widely regarded as the cleanest autofill experience for standard forms. LazyApply's fills are functional but built to feed its auto-submit engine, so quirky fields get glossed over. JobRizzer uses AI to read each field and answer it, including the messy custom questions that trip up template-based tools, then leaves the submit button to you.

The real test is the hard platforms. Workday's account-gated, multi-step flows and iCIMS's odd field structures break a lot of tools. JobRizzer targets Workday, Greenhouse, Lever, Ashby, SmartRecruiters, iCIMS, Taleo, LinkedIn Easy Apply, Indeed, and custom forms specifically. Whatever you choose, run it on one real application on your worst platform before you rely on it.

Pricing, honestly

Price structures here are genuinely different, so compare what you actually get.

• Simplify has a usable free tier; advanced AI features sit behind paid Copilot plans.
• LazyApply sells access in bulk-apply tiers, sometimes as a one-time payment, sometimes as a subscription — you're paying for application volume.
• JobRizzer gives you 30 applications free. After that you can stay free by bringing your own AI key (Gemini, OpenAI, or Groq) and paying only the model provider's tiny usage cost, or go Pro at $12.99/mo for unlimited use plus resume tailoring.

The BYOK option is worth understanding: instead of a flat subscription, you plug in your own API key and the extension uses it. For light users this can be close to free. For a fuller market picture, see our best autofill extensions roundup.

Privacy and data handling

Anything that reads your resume and fills forms is touching sensitive data, so the handling model matters.

JobRizzer parses your resume locally in the browser, sends only the specific field text an AI step needs, and never uses your data to train models. That "parse locally, send the minimum" approach limits how much of your history ever leaves your machine. With any tool, check what gets uploaded, where it's stored, and whether your data trains a model — auto-apply tools in particular tend to need more of your data on their servers to operate at scale.

Which one should you pick?

Match the tool to how you actually want to job-hunt.

• Pick Simplify if you want a polished, free autofill extension and you're comfortable doing your own resume work. It's the strongest free pure-autofill option.
• Pick LazyApply only if you genuinely want volume auto-apply and accept the quality trade-off. Go in clear-eyed about generic submissions and screening-question errors.
• Pick JobRizzer if you want assisted autofill that handles tough ATS platforms and tailors your resume per job, while keeping you in control of every submit.

If you're still weighing the whole category — including auto-apply tools and AI assistants — our guides on the best auto-apply tools and best AI job application tools lay out the full field.

JobRizzer autofills the application and tailors your resume to each posting; you review every field and submit yourself. It's 30 applications free, then free with your own AI key or $12.99/mo Pro — a middle path between Simplify's bare autofill and LazyApply's fire-and-forget volume. Whichever you land on, test it on one real application first; the tool that quietly mangles a Workday form costs you more than the few minutes it saved.
