Get a vetted shortlist of YouTube creators daily.

Claude checks every creator's views, comments and past sponsors, then writes a vetting note and a first message for each. It never sends anything: you review, edit and send.

The problem

Manual creator sourcing is slow and noisy.

For every single channel, you do it all by hand:

  1. Search YouTube, page after page
  2. Calculate the median views
  3. Check the audience stats
  4. Scan the comments for bots
  5. Check they're safe to work with
  6. Hunt for an email
  7. Add them to the CRM
  8. Draft the first message

And you keep seeing the same channels, over and over again.

That's why we built the YouTube Creator Sourcing engine. It does all of this for you →

  • Starts from one URL

    Claude proposes your setup from your website. You correct it.

  • Three ways to find creators

    Moments your product matters, competitor reviews, lookalikes of your best creators.

  • Comment check

    Real questions or generic praise, creator replies, brand-new accounts.

  • Sponsorship history

    Which competitors, how often, how recently. From the last 50 uploads.

  • Audience geography

    Where the audience likely is, with a confidence level. You set the target.

The engineYouTube Creator SourcingRuns in Claude Code
  • Emails you can trust

    Only addresses the creator published, each with its source. Never guessed.

  • A score you can read

    0 to 100, with every point explained.

  • 20-minute calibration

    Mark its calls once after the first run. It tunes itself to your judgment.

  • Safe by design

    Never sends. Claude never sees your API key. Everything stays on your computer.

  • Free to run

    Keyless out of the box. A free API key doubles the depth: 4 free runs a day.

Privacy and control

It never sends anything.

The tool finds, checks and drafts. You decide who hears from you, and what they read.

Drafts only

Every first message is a draft for you to review, edit and send yourself. Nothing goes out on its own.

Stays on your computer

Run results, notes, drafts, your brand files and your settings live in the project folder on your machine.

Claude never sees your key

You paste your YouTube API key into a Terminal helper, not the chat, and the project settings stop Claude from reading the key file.

Creator pages are untrusted

Text on a creator's channel is treated as data to read, never as instructions to follow.

Public data only

It reads public YouTube data through the official API or public pages. It never logs in.

No guessed emails

Only addresses creators published for collaborations, each with where it was found.

What it can't see. Who watches a video: commenters are the visible part of an audience, so geography is an estimate with a confidence. Sponsorships are read from video descriptions, so an undisclosed deal is invisible.

Setup guide

Set it up, step by step.

Written for people who run creator partnerships, not for developers. Every command is something you paste, and Claude can run any of them for you.

  1. Copy the repo link

    It's in your email and on the page that opens after you confirm. No link yet? Get it here: we send a confirmation link, and the repo follows.

    Here it is:

  2. Paste it into Claude A FEW MINUTES

    No Claude Code yet? Install guide ↗ It works in the Claude desktop app or a terminal, on a Mac, Linux, or Windows with WSL.

    Open Claude Code: in the desktop app, start a session in the Code tab in a folder where you keep projects, like Documents. Or type claude in a terminal. Then paste this, with the repo link and your own website:

    Install this repo and set up YouTube creator sourcing for my brand: [paste the repo link]. My website is: https://your-site.com

    Claude downloads the repo, runs the setup and then asks you one choice:

    Quick startKeyless, nothing more to set up. Results today, with lighter checks.
    Free YouTube API key (recommended)About 10 minutes, once, no credit card. Twice the depth. Step 3 shows how.

  3. Get the free YouTube API key Recommended ABOUT 10 MIN

    No credit card needed. Claude researches your brand while you do this.

    1. Create a project. Go to console.cloud.google.com/projectcreate ↗ and name it YouTube Creator Sourcing. Close any free-trial or billing offer; none is needed.
    2. Turn on the API. Find YouTube Data API v3 (not the Analytics or Reporting API) and click Enable.
    3. Create the key. Go to Credentials, then + Create credentials, then API key. Restrict it to YouTube Data API v3 only, and leave Application restrictions on None. Copy the key.
    4. Add it safely. Claude opens a Terminal tab running set_key.py. Paste the key there and press Enter. Nothing shows while you paste; that's on purpose.
      Never paste the key into the chat. Only into the Terminal helper.
    5. Check it. Claude runs a check that says works. You're on the full engine.

  4. Review Claude's proposed setup

    Claude reads your site and proposes a setup. Correct it: these answers decide the quality of everything after.

    • Competitors: direct and indirect, and who's missing
    • Existing partners to skip
    • Format: long-form or Shorts
    • Subscriber range (default 1,000 to 250,000) and the view floor
    • Audience: where it needs to be

  5. First run 15-30 MIN

    Mostly waiting. Claude then vets every creator and writes a vetting note and a draft first message for each. Nothing is sent.

  6. Calibrate 20 MIN

    Claude opens a calibration page. Mark each call right or wrong, and Claude tunes the engine to you.

  7. Optional, later: make it sharper

    Add your brand pack (your ICPs, brand guidelines and what works), and your 5-10 best videos with their results. Searches then build on what already works, including lookalikes of the creators who made it.

Troubleshooting and FAQ

Stuck? Start here.

Common snags
Google asks for a credit card

Close it. The YouTube API key is free, and no billing account is needed.

"Enable" is missing or greyed out

Check the project name in the top bar: you may have the wrong project selected. If it's the right one, the API may already be on.

It asks me to configure a consent screen

You clicked "OAuth client ID". Go back to Credentials and choose "API key" instead.

Pasting in the Terminal shows nothing

That's on purpose, so the key never appears on screen. Paste once and press Enter.

The key test fails in the first 5 minutes

New keys take a few minutes to start working. Wait a little and run the check again.

I accidentally pasted the key in the chat

Rotate the key in Google Cloud (Credentials, then your key), and add the new one with the Terminal helper.

Questions
Is it really free?

Yes. It's open source under the MIT licence and runs keyless out of the box. With the free YouTube API key, Google gives 10,000 units a day and a run uses at most 2,400, so you get 4 free runs a day. You need Claude Code to run it.

Does it contact creators for me?

No. It never sends anything. You get a vetting note and a draft first message per creator, and you decide what to send.

Do I need to be technical?

No. The setup guide is written for people who run creator partnerships. Every command is something you paste, and Claude can run any of them for you.

Where does my data go?

Nowhere. Results, notes, drafts and your brand files stay in the project folder on your computer. It reads public YouTube data only and never logs in.

Why do I have to confirm my email?

So we know the address is yours before we send anything to it. Press the button in the email, and the repo opens straight away.

Example output

crm/your-brand/notes/greenshelfstudio.md

A made-up creator and brand, to show the format. You get one note like this, and one draft, for every creator that passes.

Green Shelf Studio@greenshelfstudio · small-space plant care · UK
Advance82/100

Why: teaches plant care to renters in small flats, your exact buyer. Commenters ask real questions and she answers most of them. She ran a competitor's deal recently, so ask about exclusivity first.

Score, every point explained

Audience22 / 25 Views16 / 20 Relevance14 / 15 Contact15 / 15 Brand proof9 / 15 Geography9 / 10 Sponsored videos get fewer views than her other videos: −3

What the checks found

  • Comments: most are real questions or specific reactions ("which pot for a north-facing window?"). She replies to most. Very few brand-new accounts.
  • Audience geography: estimate, medium confidence: most of the audience in the UK. Target 50%: meets it.
  • Sponsors: worked with one of your competitors twice in her last 50 uploads, most recently a few weeks ago.
  • Email: collabs@greenshelfstudio.example, found in the description of her latest video. Not guessed.
  • Worth opening: "Repotting every plant in my flat" (entry video) and "5 plants that survive a dark bedroom".

Check first: ask for her audience screenshot before money moves, and ask when the competitor deal ends.

First message, drafted for you

SubjectGreen Shelf Studio x YourBrand || Paid Partnership
Hey Maya, I'm your name from YourBrand's creator partnerships team. Have you heard of YourBrand: yourbrand.com? Your repotting video stuck with me: the bit where you moved everything off the windowsill because the flat only gets morning light. That's exactly the moment our buyers get stuck, and it's the gap YourBrand closes. Why I'm reaching out: I'm curious to explore scoping a paid collab with you, something that could fit naturally into your small-space care videos. Happy to share some ideas, possible scope, possible rate, but I just wanted to get this on your radar first. One practical question: I saw your work with a competitor. If there's an exclusivity in place, just tell me until when and I'll come back then. No rush either way, just let me know. :)

Nothing is sent. You edit the draft, fill in the highlighted parts and send it yourself. The draft follows your own outreach structure and voice.
