Article 4 of the EU AI Act wants my team trained. LiteracyKit drafted the curriculum I couldn't.

A 'serious incident' under the EU AI Act needs a response plan. We had a panic, not a plan.

I built the FRIA trigger call as a rule, not a model. A model would have demoed better.

I almost signed an AI vendor without checking the EU AI Act. So I built the checklist I wished I had.

I couldn't say in one sentence what to tell users when we used AI. So I built a drafter.

Our incident plan was one line: escalate to legal. Article 26(5) says who to call, and in what order.

I kept deferring the DPIA because I wasn't sure it was required. Article 35 lists the triggers, and three inputs settled it.
