AI is in every professional's toolkit — worldwide. Critical judgment is not.

Lawyers, policy analysts, HR professionals, and domain experts across the US, UK, India, Europe, and beyond are using ChatGPT, Gemini, and AI tools every day: for research, drafting, analysis, and decision-making. But AI makes mistakes that look convincing. Fabricated citations, wrong facts, incorrect reasoning.

One missed hallucination in a brief, a policy note, or an HR report can have real consequences. No AI course teaches you to catch these. Lacuna does, through deliberate practice on real scenarios, with live feedback.

This is AI critical thinking training built for professionals across sectors and jurisdictions. Not generic AI education, but hands-on judgment training tailored to your domain, role, and the laws that govern your work.

of professionals report using AI tools in their work, but fewer than 1 in 5 have received any training on evaluating AI output

documented real-world AI hallucination cases in law, healthcare, and government — all available to practice on in Lacuna
