## Build Fluency Description
Most studying stops at recognition. You may remember a term or follow a definition, yet still struggle to explain the idea clearly in your own words.

Fluency is designed to close that gap.

The app helps you build a mental map of a subject by practicing explanation. Respond to prompts in writing or out loud, get structured feedback, and develop the kind of understanding that makes ideas easier to remember, use, and express.

Fluency is built on two simple principles:

- The best way to retain knowledge is to put it into your own words
- The best way to understand something is to explain it to someone else

Each session helps you:

- Clarify what you actually understand
- Notice gaps or weak connections in your thinking
- Strengthen recall through active explanation
- Build a clearer sense of how concepts fit together

Over time, Fluency helps you map the territory of a domain. Instead of isolated definitions, you build connected understanding: concepts, vocabulary, and relationships that make the subject make sense as a whole.

Domains include:

- Economics
- Psychology
- Game Theory
- Political Thought
- Western Philosophy

Whether you are studying for class, deepening your understanding, or following your curiosity, Fluency helps you move from recognition to real fluency, so you can think more clearly, explain ideas more effectively, and speak with greater confidence.
