6. 個人經驗與觀點
「記得以前寫大學論文嗰陣，最煩嘅嘢唔係搵 reference，而係 數住自己寫咗幾多字。成日差少少先夠字數，要夾硬塞嘢入去，但又唔知塞咗之後 total 幾多。後來用呢個工具，一貼就知幾多字，仲有閱讀時間同 keyword density，寫作變成一件有數據支持嘅事。字數統計唔係『數數吓』，佢係一個 將文字量化為數據 嘅工具。一篇 500 字同 2000 字嘅文章，深度完全唔同。呢個工具俾你嘅，就係 用數據去驗證你嘅寫作策略 嘅能力。」

6. Personal Insights & Expert Advice
"Back when I was writing university essays, the most annoying part wasn't finding references—it was counting my word count. I'd always be a bit short and have to pad things out, but had no idea what the final total was. With this tool, one paste tells me the word count, reading time, and keyword density—writing became a data-backed process. Word counting isn't just 'counting'—it's a tool that quantifies text into data. A 500-word article and a 2000-word article have completely different depth. This tool gives you exactly that ability to validate your writing strategy with data."
