Why Plain Language Beats Jargon: A Finance Pro's Lesson on Explaining Ideas

A finance professional writing on DEV Community recounts how a casual, conversational explanation of RAG — an AI technique for feeding documents to a model — finally made the concept click, after a formally accurate version left them confused. The experience highlights how explanations fail not because of wrong information, but because writers must guess what the reader already knows. The author argues that depth and tone are two separate dimensions of explanation that are rarely treated independently. In response, they built a tool called Clicked, which offers every term at three depth levels — Overview, Detail, and Analogy — each also available in a casual 'slang' voice. Users can set their preferred depth as a default and switch freely, putting control of how they learn firmly in their own hands.
