## Boilerplate — English

**First-Principles English** (english.ifq.ai) is a free, open-source interactive web app that teaches English through a four-layer first-principles system: sounds (phonology), roots (morphology), patterns (syntax), and logic (semantics). Instead of rote memorization of word lists and grammar rules, it builds understanding from the ground up, with a structured 4-week framework that takes learners from zero to functional English thinking.

Created by IFQ (神秘Q), an AI full-stack independent developer and founder of 捷时科技, the app features an interactive phoneme chart, root/affix explorer, sentence pattern analyzer, spaced-repetition quizzes, and progress tracking — all accessible without login or payment.

由 AI 全栈独立开发者 IFQ（神秘Q）、捷时科技创始人打造，应用包含交互式音素表、词根词缀探索器、句型分析器、间隔重复测验和进度追踪——全部无需登录或付费即可使用。

## Quotes

> "English isn't a list of rules to memorize. It's a coding system with four layers. Once you see the layers, everything else falls into place." — IFQ, creator

> "Most English learners spend years collecting words without a framework. First-Principles English builds the framework first, so words have somewhere to go." — Product description
