Simplify is one of the most popular job search tools around, especially with students and new grads, and for good reason. Its Copilot extension is free and genuinely good at filling in forms. But it's a different kind of tool from HireDue. Simplify helps you apply faster; HireDue applies for you. I work on HireDue, so keep that in mind, but here's an honest breakdown.
The short version
- Choose Simplify if you want a free tool, like picking every role yourself, and are happy to click submit on each application.
- Choose HireDue if you want an agent that finds new roles every hour, submits applications on its own (including LinkedIn Easy Apply), reaches out to recruiters for you, and keeps your data on your computer.
What Simplify does well
Simplify's Copilot is a Chrome extension that autofills applications on over 100,000 company career sites. Simplify also offers AI job matching, hand-picked lists of new-grad roles and internships, a resume builder, and a tracker for every application, interview and offer (Simplify).
The autofill and tracker are free. Simplify+ adds AI-tailored resumes, cover letters and networking tools. Its price is shown in the app, and third-party reviews in 2026 report about $39.99 a month.
Where HireDue is different
It applies, not just autofills
With Simplify, you still find each role, open the form, check the autofill and press submit. Simplify's own help pages say you review and submit every application yourself. HireDue completes the whole application, writes answers to open-ended questions and submits it, on LinkedIn Easy Apply and on external systems like Greenhouse, Workday, Lever and Ashby.
New roles every hour
Simplify helps you browse and match jobs, but you have to keep coming back to check. HireDue checks for fresh roles every hour and acts on the ones that match, so a role posted this morning doesn't wait until you next open your laptop.
Outreach from your LinkedIn and email
HireDue writes personalised messages to recruiters and hiring managers and sends them from your own LinkedIn and email accounts. Replies land in your inbox, just as if you'd written them yourself.
A desktop app with local data
Simplify runs as a browser extension and web app. HireDue is a desktop app for Mac and Windows, and your sessions, credentials and email history are encrypted and stored on your own computer. Only your resume, profile and billing details sync online.

The honest trade-offs
If you're applying to a small number of roles and want full control over each one, Simplify is excellent, and free is hard to beat. Autofill also means you check every answer. HireDue is built for people applying widely who want their evenings back: you set your preferences, and it does the repetitive work.
Which should you choose?
Students picking a handful of internships will do well with Simplify. If you're applying to dozens of roles a week and want an agent that finds, applies and follows up for you, try HireDue for free.
Competitor details come from their public websites and third-party reviews as of September 2026, and may change.
