Use AI with judgment. Build proof you own.
For people using AI at work, or moving into tech from a nontechnical role. Practice real calls, get coaching with receipts, and save proof you can defend.
Inside Datum
Practice the call. Keep the proof.
Datum is not a copilot, course warehouse, or job board. A target role becomes short workplace challenges, coaching with visible AI receipts, and proof held in a private field book.
Target: AI operations coordinator. First move: inspect one real workflow and name the decision the role is responsible for.

Target role
Name the room you are trying to enter.
Choose one specific role in software, AI applications, data, automation, or related work. Datum turns that target into a route instead of another feed to refresh.
Compare two model outputs, choose the safer route, and explain the tradeoff in words you would use with a team.

Practice
Train the call, not the autocomplete.
Short workplace challenges turn frontier concepts into work you can inspect. Practice is tied to the role you chose, not a warehouse of courses.
A coaching note with the source, the model receipt, the uncertain part, and the next question you should answer yourself.

Coach
Get help with the decision in front of you.
Coach works through the choice without hiding the model behind it. Every answer shows what was sent, what stayed on your device, and what still needs verification.
The work, the decision, the evidence, and the line you can explain without handing authorship to a model.

Proof
Save an example you can defend in a room.
Finished practice becomes proof you own. Datum helps you choose the evidence and check the claim, while every resume bullet remains yours to write.
Datum feature · Trace
The route remembers the work, not your behavior.
Trace is the continuity feature inside Datum. It keeps sources, coaching receipts, changes, confirmations, and unresolved context attached to the proof. It does not create a public profile, score activity, or turn system inference into your decision.
The sovereignty contract
Your proof is not inventory.
AI use stays visible
Coach shows what left your device, which model answered, and what still needs checking.
The work stays yours
