Summary
How does Four-Leaf compare to Simplify?
Simplify is an AI job search platform built around a Chrome extension called Copilot that autofills job applications in one click across what the company describes as over 100 job boards and application portals, including Workday, Greenhouse, iCIMS, Taleo, Avature, Lever, and SmartRecruiters. Around that extension it wraps a job-matching engine, an ATS-scoring resume builder, an application tracker that automatically logs anything submitted through Copilot, and AI tools for cover letters, application questions, and outreach emails. Simplify publishes no pricing page. The URL simplify.jobs/pricing returns a 404 and the plans link redirects into a signed-in profile page. Its help center lists Simplify+ at $19.99 for one week, $39.99 for one month, and $89.99 for three months, all with identical features. The autofill extension, application tracker, and job matches are free.
Four-Leaf is an all-in-one AI job search assistant ($5 / 5-day pass or $20/month Pro) that includes voice mock interviews across 24+ roles, AI resume tailoring, cover letters, LinkedIn optimization, AI job search, salary negotiation coaching, and email drafting. Both cover resume tailoring, ATS match scores, cover letters, job matching, and application emails. The difference is where each puts its weight. Simplify optimizes throughput, getting more applications submitted faster. Four-Leaf optimizes what happens after, with spoken mock interviews and negotiation coaching. Simplify's own AI Interviewer page does not mention voice, speaking, or audio, and its salary negotiation is delivered by human recruiters as a separate service.

Positioning
Which one is right for you?
When Simplify is the better choice.
- Your bottleneck is application volume. Nothing here matches one-click autofill across 100 or more portals for sheer throughput.
- You are a student or new grad on a deadline-driven recruiting cycle. The free tier plus a $19.99 one-week option fits a short seasonal search.
- You want applications to log themselves. Anything submitted through Copilot lands in the tracker automatically.

Does Simplify have mock interviews?+

Four-Leaf runs spoken mock interviews where you answer out loud and get feedback on delivery as well as content.

Simplify does not publish a pricing page. The URL simplify.jobs/pricing returns a 404 and the plans link redirects into a signed-in profile.
