Simplify for filling. CoBlack for applying
Simplify fills application forms in one click. CoBlack sources, matches, and submits without you present.

Simplify launched in 2021, joining Y Combinator's Winter cohort with a clear, focused product: a Chrome extension that fills job application forms automatically so you don't have to retype your name and experience into every Workday or Greenhouse portal. The tool now claims 1.5 million users and 200 million applications submitted. For a category full of noise, that kind of traction is worth taking seriously.
What Simplify does is genuinely useful. What it doesn't do matters just as much.
What Simplify does
The core product is Simplify Copilot, a free Chrome extension that autofills applications across 100 or more ATS platforms including Workday, Greenhouse, Taleo, Lever, and iCIMS. You stay in the loop at every stage. When you find a role and click apply, Simplify fills the fields. You review the answers and submit.
A premium tier, Simplify+, adds AI-tailored resumes, cover letters, and ATS keyword scoring. Pricing runs $39.99 per month, $89.99 for three months, or $19.99 per week. The free version is comprehensive enough that most users report no need to upgrade.
Simplify also maintains a job database, a tracker, and a networking tool for approaching hiring managers. It is a full-stack job search platform, not just an autofill extension.
What the reviews say
The Chrome Web Store rating is 4.9 out of 5 from over one million installs. On that metric, the autofill product delivers. Users in r/cscareerquestions and r/csMajors specifically praise Simplify on Workday and Greenhouse forms, noting zero fill errors on standard portals at Google, Meta, and Amazon.
Trustpilot tells a different story. Simplify holds a 3.0 out of 5 across 9 reviews there, with 67 percent rated one star and 33 percent rated five stars. The middle is empty. One-star reviewers cite a no-refund policy on Simplify+, billing reversals that went unresolved, and concerns about Simplify's practice of publishing user support queries on a public forum. An independent analysis of 90-plus Reddit comments found a consistent message: the free extension is excellent; the paid tier is not worth $39.99 given the AI quality and lack of a trial.
Where CoBlack stands
The gap between Simplify and CoBlack starts before the application. Simplify autofills an application you found, on a job board you visited. CoBlack's Kosmos Engine pulls openings directly from employer ATS feeds and verified career pages before they appear on LinkedIn or Indeed. Ghost listings, expired postings, and roles filled internally do not reach CoBlack's inventory.
The second difference is who does the submitting. Every application that leaves through Simplify requires a person at the keyboard to click submit. CoBlack applies server-side. You close your laptop and the search keeps running.
The third is matching. Simplify scores your existing resume against a job description. CoBlack builds a Career Capability Map from your demonstrated experience and applies only when the fit score reaches 70 percent or above. Every outgoing application includes a resume tailored to that specific job description, not a static document passed through a keyword scorer.
CoBlack users convert to interviews at 12 times the rate of a standard search (CoBlack internal data, 2026). That result comes from the combination: sourcing from verified ATS feeds, matching from capability not keywords, and submitting without requiring the job seeker to be present.
Who each tool is for
Simplify is well suited for job seekers who are comfortable running their own search and want to stop retyping the same information on every application. If you already know where to look and you just want the friction removed, Simplify Copilot is one of the best free tools in the category.
CoBlack is built for the same person when they want the search itself to run without them. Applications source from verified employer feeds, match against a capability profile, and go out while the browser is closed. For job seekers who want to stop managing the pipeline and start managing the interviews, the two products answer different questions.
Simplify removes the typing. CoBlack removes the task.
