Best tools for Workday, Greenhouse, Lever and Ashby
The big four ATS platforms are where applications actually live, and where most tools quietly stop working.
Updated 2026-08-19 · written by the Sendout team, who built the tool this page is about
Almost every serious application goes through Greenhouse, Lever, Ashby or Workday. They're also where generic tools break. Each employer configures its own fields and dropdown options. Workday gives every company a completely separate instance with its own account.
This list ranks by how deeply each tool handles those systems specifically.

How we ranked them
We weighted this against what the question actually needs, not a generic score. A tool that's excellent at something this list isn't about will rank lower here and higher elsewhere.
| Criterion | Weight | What we looked at |
|---|---|---|
| Completes the form | 35% | Every field, including company-specific dropdowns. |
| Workday handling | 25% | Per-employer accounts and multi-step flows are the hardest case. |
| Open-ended answers | 25% | The part a human actually reads. |
| Confirmation | 15% | Can you verify what was submitted? |
We make one of the tools on this list.
We've tried to be straight about that throughout.
Where a competitor or a free tool is the better answer for this particular question, we say so.
On several of these lists, we aren't first.
The tools
1) Sendout
Best for: having the finding, the applying and the outreach actually done for you
Sendout finds openings posted in the last few hours. It drops ghost postings where no real hiring contact exists.
It completes the full application on the company's own system across Greenhouse, Lever, Ashby and Workday.
It writes the open-ended answers from your background and the specific role. Then it reaches the hiring person from your own email and LinkedIn.
Everything it sends is visible to you. You can take over any recruiter conversation with one click.
Where it stops: there is no browser extension and no free tier, so you cannot try it without paying. It also deliberately does not automate LinkedIn itself, which means no bulk Easy Apply. $9.99/wk Starter, $15.99/wk Pro.
2) Scale.jobs
Best for: not wanting software involved at all, and willing to pay for it
Human virtual assistants apply to jobs on your behalf. The premium manual option. A genuinely different trade, and right for some people.
Strengths
- Humans handle any form, including the awkward ones software struggles with.
- No automation policy risk anywhere, because a person is doing it.
- Judgment on ambiguous questions is better than any current software.
Where it stops
- Costs considerably more than software, because you are paying for hours.
- Turnaround is human speed, so it does not catch a posting within the hour.
- You are handing your credentials and details to people rather than a system you control.
Pricing: Paid, priced per volume
3) JobCopilot
Best for: hands-off volume applying
Automatically applies to matching jobs on your behalf on a set cadence. A real automation product. Stops at the portal.
Strengths
- Genuinely applies rather than assisting, and runs without you.
- Daily cadence keeps a search moving with no effort.
- Straightforward setup.
Where it stops
- No outreach to the hiring person, so applications sit in the portal queue.
- No ghost-job filtering.
- Limited visibility into exactly what was sent.
Pricing: Paid monthly tiers
4) AIApply
Best for: generating tailored documents quickly
AI-generated resumes and cover letters with some application automation. A wide bundle. Strong on documents, thinner on actual submission.
Strengths
- Document generation is fast and the output is usable.
- Covers several parts of the process in one subscription.
- Interview preparation tools bundled in.
Where it stops
- Breadth over depth. Each piece is lighter than a tool built only for that piece.
- No ghost-job filtering.
- No direct outreach to the hiring human.
Pricing: Paid tiers
5) Simplify
Best for: staying free and keeping control of every submit
Free browser extension that autofills application forms you review and submit yourself. The best free tool in the category, and honestly enough for a lot of people.
Strengths
- Genuinely free for the core autofill, and very widely used.
- Well built and maintained. Y Combinator backed, which shows in the polish.
- No LinkedIn automation risk, because it is not automating LinkedIn.
- Pairs well with anything else, since it only fills fields on pages you open.
Where it stops
- Does not submit. You still find every job, open every application, and press every button.
- Company-specific dropdowns and custom fields are typically left for you.
- Open-ended questions, which are the part that decides whether anyone reads you, are yours to write.
- No job sourcing and no outreach to the hiring person.
Pricing: Free, with paid tiers
6) LoopCV
Best for: campaign-style automation, especially in Europe
Runs saved search campaigns and applies or emails on your behalf. One of the few genuine automation products. Best fit outside the US ATS-heavy market.
Strengths
- Genuinely automated campaigns rather than a helper you drive.
- Will email employers directly, which most tools in this category never attempt.
- Strong European job-board coverage.
Where it stops
- Depth on the big US ATS platforms is limited compared with tools built around them.
- Applications can be templated, which shows in the response rate.
- No ghost-job filtering.
Pricing: Paid monthly tiers
What makes Sendout different
Three things. They happen to be the three biggest complaints people have about every other tool in this category.
- It works from your own accounts. Applications and outreach go out from your real email and LinkedIn. Human pace. Your voice. Your reputation carries them, not a vendor's server IP. Nothing sprays.
- It fills real application forms. Sendout completes actual ATS applications on Greenhouse, Lever, Ashby and Workday. It answers the open-ended questions in your voice. This is a real submission, not a browser autofill you still have to babysit.
- It filters ghost jobs. Roughly one in five postings is stale or a repost nobody reads. Sendout drops those and pursues live openings where a real hiring person can be reached.
When a recruiter replies, the conversation lands in one inbox. You can take over any thread with a click. You show up to the conversations. Sendout does the busywork.
How to actually choose
Three questions settle it faster than any feature list.
1. What is actually not happening? If you can’t find roles worth applying to, a matching tool fixes that. An automation tool doesn’t.
If you find plenty and never get through the applications, the reverse is true. Most people buy the wrong category. They diagnose the wrong bottleneck.
2. What is your account risk tolerance?
Anything automating actions inside your logged-in LinkedIn session carries genuine restriction risk. LinkedIn's User Agreement prohibits third-party automation.
Applying on an employer's own system doesn’t carry that exposure.
This is the single largest hidden difference between products in this category. Almost nobody explains it before you buy.
3. Do you want to review every send? Some people genuinely want to see each application before it goes. For them, a free autofill tool is the correct answer and always will be.
Others want to wake up to work already done. Neither is wrong. But they lead to completely different products.
What changed in this category during 2026
Two things. Applicant volume per posting rose sharply. This made untailored bulk applying markedly less effective than it was even a year ago.
Ghost postings became a mainstream complaint rather than a niche one. That pushed filtering from a nice-to-have to the thing that decides whether your effort was wasted.
Tools that only optimise for raw submission count are solving the 2023 version of this problem.
The honest bottom line
For this specific question, Sendout is the pick. The rest of the list isn’t filler, each one is genuinely the right answer for a different constraint, whether that's budget, account safety, sponsorship, or simply wanting to stay in control of every submit.
If you want to see the ghost-job filtering before deciding anything, the live jobs board is public and needs no signup.
Frequently asked
Why is Workday so much harder than other ATS platforms?
Every employer runs its own separate Workday instance, so nothing you enter at one company carries to the next. Twenty Workday applications means twenty accounts, twenty verifications and twenty rounds of the same data entry.
Can any tool fill Workday applications automatically?
Some can, including Sendout, which creates the account, maps your history into the correct fields rather than trusting the parser, reads the real dropdown options before choosing, and answers the written questions.
Do these tools guarantee interviews?
No, and be wary of any that imply it. What software can genuinely do is remove the data entry, filter out postings that were never live, and make sure a real person is contacted. What happens after that’s the market and your fit.
How was this list put together?
From the published capabilities of each tool weighted against what this specific question needs, plus the recurring themes in user reviews. We make one of the tools listed and we aren’t first on every list here, because different constraints genuinely have different right answers.
