鎖定 macOS 的本機優先 Markdown 研究工作台
並排雙欄閱讀器，讓 PDF 與 Markdown 編輯器同時呈現，邊讀邊把標記與註解寫進筆記。
從 PDF 中繼資料產生 BibTeX 或 APA 引用，每條引用都連結回原始標記，幾個月後仍能一鍵回到出處。
Premium 功能，依含義而非精確關鍵字檢索文獻庫，由裝置端模型驅動，內容不上傳。
筆記與文獻之間的雙向連結建立視覺化關係圖譜，並可匯出為 Neo4j 友善格式。
即時 AI 答案引擎與研究工作區，將聯網引用與前沿推理模型結合。
跨數百個來源執行多步驟迭代式網路與文件研究，交叉核對事實並產生結構化、帶引用支持的分析報告，可匯出為 PDF 或分享為互動式 Perplexity Pages。
讓 Pro 與 Max 訂閱者在 Perplexity 自有 Sonar 模型與頂級外部模型（包括 Claude 4、o3-pro 與 Gemini）之間動態切換，或並排比較多模型推理結果。
提供專屬專案工作區，使用者可上傳本機 PDF、試算表與文字檔，設定自訂助理指令，並執行結合私有文件檢索與即時網際網路搜尋的查詢。
將 Perplexity 從被動的問答擴展到代理式執行，透過 Comet 生態把高層使用者請求轉化為已完成的工作流程、多分頁瀏覽器操作與自動化資料綜合。

利用 Google 龐大的搜尋索引提供即時解答，但提供的是標準聊天介面，而非深度的研究動態。
Integrates real-time social data search for breaking news, but leans more toward casual chat than structured research.
提供具代理能力的多來源研究與網頁生成功能，但相較於 Perplexity 乾淨的解答引擎，可能會顯得較雜亂。
專項更強Offers a comprehensive free index of academic literature, but lacks conversational chat synthesis for general web queries.
專項更強與 Perplexity 廣泛的一般網路搜尋不同，它專注於經同儕審查的科學論文，以提供基於證據的解答。
Combines privacy-focused web search with AI summarization, though it requires a paid subscription for full access.
Jenni is an AI research and academic writing workspace that helps students, researchers, and academics read, write, and cite in one place. Bring in PDFs or import a Zotero or Mendeley library, and Jenni's autocomplete suggests sentences grounded in your own sources, with every suggestion linked to the exact page and paragraph. A built-in writer, AI chat, citation engine covering 10,000+ styles, and a Reviews tool for catching weak or unverified claims make it a full environment for producing cited papers.
專項更強Analyzes scholarly article citations to verify scientific claims, making it superior for academic literature reviews.
