Term of the day
AI bias
When an AI system's outputs are systematically unfair to some groups, usually because of patterns in its training data or how it's used.
The glossary.
The business words technical people meet at work, in plain English. What they mean, how you'll hear them, and why they matter to you.
Decode a sentence.
Paste the email that confused you. Glossary terms are highlighted; select one to see what it means.
How it works: a few lines of JavaScript match your text against the glossary, in your browser. No AI, and nothing you paste is sent anywhere.
