Guide

Everything you need before you press start.

How to set up, what each of the seven steps asks of you, and what every number on the screen means. Read it once; the test itself explains as it goes.

Before you start

Six things that make it go smoothly.

Sixteen quiet minutes

The test pauses if you switch away, but it goes better in one sitting. Silence notifications.

Camera at eye level

Your face should fill the middle of the preview. A laptop on a desk is fine; a phone propped below your chin is not.

Light on your face

A window or lamp in front of you, not behind. A dark picture reads as blank and pauses the test.

A recent Chrome or Edge

The face check runs in your browser and needs a modern one. Safari and Firefox work, but the camera model is slower.

A microphone, optionally

For two short spoken answers at the end. Typing scores exactly the same, so this is a preference, not a requirement.

One screen, if you can

Looking at a second monitor counts as eyes off screen. Nothing fails, but the seconds add up on your record.

The seven steps

About sixteen minutes, start to finish.

  1. 1

    Pick your kind of work

    1 min

    Choose the field closest to what you do, or paste a job advert and the task is built for that role. The ready-made test starts instantly; a fresh one takes about thirty seconds.

    The ready-made one is a real test. It is just built already.

  2. 2

    Read what is recorded, turn on the camera, agree

    1 min

    Two lists: what we record and what we never do. Then the camera check: allow it, sit so your face is in the frame, and wait for the chip to say Eyes on screen. Enter your name and start.

    The name you type goes on your credential. Use the one you would put on a CV.

  3. 3

    Read the situation

    2 min

    A short brief, a deliverable, and the documents you have been given. Read the documents. Your AI teammate will quote some of them and skip others, and the difference is where the mistakes hide.

    Note which tools your teammate can open. You will want to ask what it actually checked.

  4. 4

    Do the work, with your AI teammate

    10 min

    Write your deliverable on the left. Ask your teammate anything on the right. It looks things up, has opinions, and is confidently wrong four times. Every reply shows what it opened before answering.

    When it sounds certain, ask for the evidence. 'What did the per-page numbers say?' is worth more than any prompt trick.

  5. 5

    Judge ten AI answers

    3 min

    Ten things an AI said, one at a time. Rate how far you would trust each one. Some are right but hedged, some are wrong but certain, two would be unsafe to act on.

    You are scored on whether your confidence matched reality, not on getting a right answer.

  6. 6

    Explain two of your own choices

    90 sec

    Two questions about decisions in your own work. Speak or type. This is the part nobody can paste an answer to, and it is how we know the author is the person in the chair.

    Name specifics. 'I rolled back because the checkout page alone was failing' beats 'I used my judgement'.

  7. 7

    Get your results, and keep them

    30 sec

    Six skills, each opening into the exact moments behind it. Untick anything you do not want to share, build the shareable version, and it is yours.

    Skills you never demonstrated say unproven. That is honest, not a bad mark.

What the numbers mean

Every count on your screen, explained.

These sit in a strip above your workspace, and the camera ones under your preview in the corner. They are counted openly and go on your record as numbers for a person to read. None of them fails anything on its own.

Tab switches
Times you left the tab or window for more than a moment.
Left full screen
Times you exited full screen during the test.
Copied out
Times text was copied from the test.
Seconds away
Total time the tab was hidden or unfocused.
Looked away
Stretches where your eyes were off the screen for more than a moment.
Eyes off screen (s)
Total seconds of those stretches, including eyes closed.
Camera blank (s)
Seconds the picture was black, covered, or the camera was off.
No face (s)
Seconds with nobody in frame.
Warnings
Two, for a problem that goes on: leaving the tab or full screen, no face, a second person, eyes away for a while, or a dark camera. A third ends the test and scores what you have done.

Eyes on screen: the camera sees one face, looking at the screen.

Looking away / Eyes closed: counted after a moment, stops when you look back.

Camera blank / off: the test pauses until the picture is back. Nothing is lost.

For employers

Three steps, no account.

Turn a job advert into a test

Paste the advert, or drop the PDF. We work out which six skills the role really needs and weight them. It usually rates judgment higher than the advert does, because adverts overdo the tools.

Open the employer view

Find who fits, and see the gap

Coverage, never a verdict: what share of the role each candidate has proven, and exactly what they have not. Every number opens into evidence quoted from the session.

Find who fits

Verify a credential a candidate sends you

Paste it. It is checked in milliseconds against our public key, offline, with no account. Change a character and it fails. You can also see whether anything was withheld.
