Why we built it

It isn’t you. It’s which doors.

Most employers have never sponsored a visa. Send 500 applications their way and every silence feels like a verdict on you.

It isn’t. Those doors were never going to open. Knock points you at the ones that can.

Read why we built it

An illustration of 120 employers: most have never sponsored anyone, a few have, and fewer still fit you. The real share changes by country, field and year.

What it does

Find. Rank. Fill. You send.

Five things go in. A ranked shortlist comes out: Best fit, Good fit, Stretch. Hover any part to see what it means. How Knock weighs them stays with us.

The other side of the desk

Built as the opposite of a bot.

Recruiters now get hundreds of bot applications per job, so “needs a visa” starts to look like spam. Knock keeps you clearly human.

Questions

Fair questions

Will it get me a job or a visa?

No tool can promise that, and you should be wary of any that does. Knock helps you spend your effort on employers who have sponsored before, and makes each application faster.

Does it apply for me?

No. It fills the form and stops at Submit. You check and send.

Will recruiters think I’m a bot?

It’s built so they don’t: your real resume, nothing invented, nothing sent by a bot, and no-sponsor jobs hidden.

Is it really free?

Yes. Search, sponsor records, the tracker and 10 filled applications a week cost $0. No card.

Where does my data go?

It stays in your browser. If you turn on sync, a copy is kept in your Knock account so you can use another computer. Details
