AI 文件生成器教學：用 AI 幫你寫辭職信、求職信、推薦信
1. 導言
無論你係準備辭職、搵新工、定係需要寫推薦信畀同事，正式文件嘅撰寫往往係最頭痛嘅環節——唔知點樣開頭、用咩語氣、點樣表達先得體。我哋嘅免費 AI 文件生成器專為解決呢個問題而設：揀文件類型、輸入基本資料，AI 就會幫你生成一份完整嘅文件，慳時間之餘仲保證專業得體。而且 100% 純前端運算，你嘅資料唔會離開瀏覽器，保障私隱。
2. 背景與概念解釋
AI 文件生成器嘅背後技術係大型語言模型（LLM），通過分析海量正式文件嘅結構同用語，學習唔同文件類型嘅寫作模式。當用戶輸入關鍵資料（如公司名稱、職位、原因等），AI 會根據這些資料自動生成結構完整、語氣合適嘅文件內容。
市面上嘅 AI 寫作工具通常需要將資料上傳到雲端伺服器處理，有數據外洩風險。我哋嘅工具採用純前端技術，所有資料處理喺你嘅瀏覽器內完成，確保個人資訊唔會外流。
3. 實際應用場景
- 職場離職與轉職：需要寫辭職信但唔知點開口？輸入公司名同最後工作日，AI 幫你生成專業辭職信。
- 求職與面試準備：寫求職信時唔知點樣突出自己？輸入應徵公司同職位，AI 幫你組織亮點。
- 團隊管理與表揚：要寫表揚信畀表現優秀嘅同事，但唔知點寫先夠真誠？AI 幫你打好草稿。
4. 使用步驟
- 選擇文件類型：從下拉選單選擇你需要嘅文件類型（辭職信、求職信、推薦信、警告信、表揚信、感謝信、投訴信、道歉信）。
- 輸入基本資料：根據提示填寫相關資訊（如公司名稱、職位、原因等），欄位會隨文件類型自動變更。
- 選擇語氣：選擇「正式」、「輕鬆」或「暗黑」三種語氣，配合不同場合同個人風格。
- 生成文件：點擊「生成文件」，AI 會喺數秒內產出完整文件。
- 複製或下載：滿意內容後可以一鍵複製或下載為 .txt 檔案。

Free AI Document Generator Guide: Write Resignation, Cover & Recommendation Letters with AI
1. Introduction
Whether you're preparing to resign, looking for a new job, or need to write a recommendation letter for a colleague, formal document writing is often the most challenging part—not knowing how to start, what tone to use, or how to express yourself professionally. Our free AI Document Generator solves this problem: select a document type, enter basic details, and AI generates a complete document for you, saving time while ensuring professionalism—all with 100% client-side processing to protect your privacy.
2. Background & Technical Concept
AI document generators leverage Large Language Models (LLMs) that analyze vast amounts of formal document structures and language patterns to learn writing styles for different document types. When users input key details (company name, position, reason, etc.), the AI automatically generates well-structured content with appropriate tone.
Unlike many AI writing tools that require uploading data to cloud servers—creating privacy risks—our tool uses client-side processing. All data stays in your browser, ensuring your personal information never leaves your device.

- Team Management & Recognition: Need to praise a high-performing colleague but don't know how to sound sincere? AI drafts it for you.
4. Step-by-Step Usage Guide
- Select Document Type: Choose from 8 types (resignation, cover letter, recommendation, warning, praise, thank you, complaint, apology).
