Workflows, prompts, and tactical builds for using AI to find candidates faster, cheaper, and with less LinkedIn noise. Updated continuously as the tools change.
- Map any role's realistic talent pool in under two hours
- Find senior engineers who are invisible on LinkedIn via GitHub
- Send 40 personalised outreach messages a day without burning out
- Stop guessing which AI tools are worth your time
Why I built this
The 90-second pitch from Michal.
If you're recruiting in 2026 and your AI workflow is still 'paste into ChatGPT', watch this first.
Workflows inside AI Sourcing Lab
Each is one outcome, copy-able prompts included. Updated continuously.
8 min
AI Talent Mapping
Produce a defensible talent map of any role in under two hours.
Combine Claude with a few public datasets to chart the realistic supply of candidates for a role, with company clusters, seniority bands, and red flags — before you open the first profile.
7 min
Claude Outreach Personalization
Send 40 outreach messages a day that each feel hand-written, in under 90 minutes of work.
Personalization is the single biggest reply-rate lever in cold sourcing, and the part most recruiters skip when volume goes up. This workflow uses Claude to generate the *personal* line of each message from one paragraph of real input — and bans every recruiter cliché in the process.
9 min
GitHub Proxy Sourcing
Find senior engineers who are invisible on LinkedIn by going through their code.
When LinkedIn returns 12 stale profiles, GitHub still has the people. This workflow uses GitHub search + Claude to surface engineers with verifiable, recent, relevant work — then pulls them into a shortlist with a working hypothesis for each candidate.
Live Builds

Guides
Short videos that turn AI tools into recruiter weapons.
Loom walkthroughs on Custom GPTs, Claude Skills, Gemini Gems, Claude Cowork. Watch, copy the steps, run on a real role.
How to use Skills in Claude Cowork
Claude Cowork is the multi-tab side-by-side workspace inside Claude. Drop a sourcing skill into one tab, a screener into another, and run them against the same role with shared context.
How to use Gems in Gemini
Gems are Gemini's version of custom assistants. The setup is similar to Custom GPTs but the Workspace integration changes a few things — here's the recruiter-specific walkthrough.
How to use Custom GPTs in ChatGPT
Custom GPTs let you save a Lab template as a dedicated assistant inside ChatGPT. Pin it to the sidebar and open with one click instead of pasting instructions every session.
4 guides inside — new ones drop with every Live Build.

Frequently asked
Is this a course?
No. It's a continuously-updated library of operational workflows, with live builds and a marketplace inside. You don't watch lessons — you implement systems.
How is this different from a generic 'AI for recruiters' resource?
Every workflow is scoped to a specific outcome a recruiter actually needs — sourcing, enrichment, outreach — and tells you the tools, the steps, and the prompts. No theory, no fluff, no motivational language.
What tools do I need to subscribe to?
At minimum: Claude (paid plan recommended, free works for most workflows) and a spreadsheet. Some workflows reference LinkedIn Recruiter or specific enrichment tools — but the core is reasoning + structure, not vendor lock-in.
Can I cancel anytime?
Yes. Monthly subscriptions cancel from your billing page; access continues until the end of the period you paid for.
What if my company wants to buy access for the whole team?
Team plans cover up to 10 users for one Lab (€249/mo) or all Labs (€399/mo). Buy from the team page after signing in, or talk to us if you need more than 10 seats.
Will this still be useful in a year as AI changes?
That's the point of the format. Workflows are revisited monthly and the freshness stamp tells you when each one was last verified. If the underlying tool changes, the workflow gets updated — not retired into a graveyard of stale tutorials.
