Your AI Needs a Judge

Last Wednesday's mastermind surfaced a great use case for improving your AI usage in measurement.

Jordan Hill, one of our MeasureU mentors, walked us through how he uses a tool called Jev.

Here's the plain version: Jev is an AI model that acts like a referee for your other AI activities. You give it your rules, it checks each answer AI returns against them, and tells you pass or fail. Fast, cheap, no installation required.

Jordan still uses regular AI for most of his work. Jev just checks it. He said it gave him real confidence that the AI wasn't going off-script, and he also uses it to make sure his AI agent picks the right tool for each job.

Another member showed something even simpler. She runs her morning news feed through Jev against her own criteria to filter out the noise. One morning it kept 2 articles and skipped 43. She read what mattered and moved on.

One easy way to try it is OpenRouter, a unified interface for every AI model, Jev included.

If you haven’t heard of Jev yet, no worries. It was just released to the public on September 15.

Why are people jumping on the Jev train so fast? Because practitioners who use AI every day but care about their professional reputation have been dying for checks like these to build into their process.

This is the pace of the conversations happening inside the MeasureU community right now. I’m going to work harder to use this Monday newsletter to surface the ideas that matter most to you.

Has AI been inconsistent for you? If so, there's probably a check you can build around it too.

To Your Measured Success!

P.S. MeasureSummit is this Wednesday and Thursday, October 7–8, and it's free to register.

P.P.S. My favorite AI model release of 2026 is Claude Opus 5.5, hands down. It’s the best AI model I’ve worked with and can one-shot my most complex ideas into something useful like no other.

Coming Up This Week at MeasureU

Quiet the Noise: Build a PPC Operating System, Not a Prompt Library (with Alina Popa)

Tuesday, October 6, 10:00 AM – 12:00 PM EDT

Turn the weekly PPC grind into a Monday queue: a structure your account keeps, so you spend your time on decisions, not on retrieval. Alina Popa walks you through her working system file by file, and you leave with the templates, the method files, the three Google Ads scripts, and two finished example accounts to copy the shape from. The session: Two hours, one working system. A guided demo of the files, the scripts, and the workflow, then 30 minutes of Q&A on your own account. When: Tuesday, Oc

The AI Tracking Audit (with Jordan Hill)

Tuesday, October 6, 1:00 PM – 3:00 PM EDT

A tag fires twice. A trigger stops matching after a site update. None of it announces itself, and finding it by hand takes hours. On October 6 you build a complete AI-assisted GTM audit from zero, checkpoint by checkpoint, with Jordan Hill. Then the teardown Q&A: attendee containers get audited live, with feedback on the results and a fix plan. You leave with a prioritized findings list for your own container and a process you can run again. The session: Two hours on your real setup. You build y
