The job exists before the ad
A manager who gets a hiring budget does not go to the careers site first. They post: "we're opening a project manager role, the ad is coming, but if you know someone…". Their network shares it, applications arrive by private message, and by the time the official ad is finally online, two interviews are already scheduled. Some roles never go through an ad at all.
LinkedIn's job alerts do not see those posts: they only watch the ads published under the Jobs tab. A role announced in the feed is just a post, in the hiring manager's own words: "we're hiring", "role open", "we're looking for", "DMs open", "not online yet".
Prosko watches those words, crossed with your line of work, in the LinkedIn feed and search, and sends you every post that contains them — the person who is hiring, their job title, the excerpt, the direct link. You apply while the list is still short.
The rule that catches these posts
For a job search, the rule crosses a hiring phrase and your line of work.
A multi-word trigger fires when all of its words appear in the post, in any order; case, accents and hyphens are ignored. "We're hiring" is deliberately broad: it is the most frequent phrase, and the intent given to the AI assistant does the sorting — "a project manager role, in Nantes or remote, announced by the person doing the hiring". The assistant re-reads the posts picked up and discards the rest: hiring posts in another field, agencies "hiring for a client", advice on "how to hire".
Exclusions cut what you do not want from the start: internships and apprenticeships if you are not after those, freelance assignments if you want a permanent contract. Adjust them after a few days, based on what wasted your time.
What it catches
Two posts like the ones a rule of this kind surfaces in an ordinary week. The names are made up; the phrasing is not.
"We're hiring for a role that isn't online yet: a project manager to run two products. Permanent, Nantes or remote — DMs open, and the official ad can wait."
"Our team is growing: we're looking for a project manager to structure our launches. No perfect job description, more of a conversation. Write to me."
Neither went through the Jobs tab. The first says so in as many words; the second may never become an ad at all. In both cases, the person hiring is the author of the post, and they read their messages.
The alert you receive
"We're hiring for a role that isn't online yet: a project manager to run two products. Permanent, Nantes or remote — DMs open, and the official ad can wait."
The person hiring, their job title, the excerpt where the words appear, the link to the post. "Checked by the assistant" means the assistant re-read the post and confirmed it matches the intent you described. Alerts pile up in the extension — the last five hundred — and, if you wish, in a Slack or Discord channel only you read.
Apply while the list is short
The same day. A hiring post gets most of its replies within twenty-four hours. After that, the recruiter sorts what they have. Being among the first ten messages counts for more than having the perfect cover letter.
Reply to the person, not to the role. The post tells you who is hiring and why: "run two products", "structure our launches". A message that picks up those words and answers them in three lines gets read; a CV attached without a word does not.
A comment, then a message. A short comment under the post — a precise question, or simply "sending you a DM" — makes you visible to the author and to their network. The private message does the rest.
Keep a record. Every alert stays in the extension with the date and the link. A role you did not reply to last week is still a lead this week: the official ad, for its part, may still not be online.
What to know before you start
- Your LinkedIn account is enough. Free or Premium, Prosko reads the feed and the search as your account displays them. No additional LinkedIn subscription is needed.
- Discreet by design. Prosko turns nothing on in your profile, publishes nothing, sends nothing: your current employer sees no signal. What you send the recruiter, you write yourself.
- Everything runs in your browser. No server, no account on our side: your keywords and the roles you find never leave your machine. In return, monitoring works while Chrome is open.
- Alongside LinkedIn's job alerts, not instead of them: those cover the Jobs tab, Prosko covers the feed and the search — where roles are announced first.
Frequently asked questions
Does it replace LinkedIn's job alerts?
No, it complements them. LinkedIn's alerts watch the ads published under the Jobs tab. Prosko watches posts — the feed and the search — where many roles are announced before the ad, or without an ad at all. Keep both.
Can my employer tell that I am looking?
No. Prosko changes nothing on your profile, turns on no banner, publishes and sends nothing. It reads what LinkedIn displays and passes it on to you, in your browser. The only visible thing is what you choose to write to the recruiter.
How do I target my role and my city?
Describe them in one sentence in the intent given to the AI assistant: "a project manager role, in Nantes or remote, permanent". It discards posts that do not match. You can also add the role's name to the triggers to narrow further.
Does it work for roles in French?
Yes. The watched words are the ones you write: "we're hiring" and "on recrute" can live in the same rule.
What does it cost for a job search?
The trial is free for 30 days, no card required — often the length of an active search. After that, €6.99 a month, cancel any time.
