為思維打造的工作室：以物件相連的筆記
把人物、書籍、專案與會議建模為帶屬性的類型化物件，而不必硬塞進資料夾。
一眼看到指向某條筆記的所有連結，並讓 Capacities 找出你寫過卻未連結的相關內容。
先隨手記錄，不必立刻決定歸屬，之後再連結與整理。
付費方案中 AI 助手與筆記協同工作，圖片、PDF 與網頁連結分析可把外部素材變成可用內容。
Open WebUI is an open-source, self-hosted AI interface that lets individuals and organizations run any model — local or cloud — inside a workspace they fully control. It ships as a one-command install, supports Ollama, OpenAI-compatible and Anthropic endpoints, and extends through Python tools, functions and pipelines.
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
免費 / 開源主要作為本地模型的輕量級 CLI 執行環境，而非功能齊全的聊天介面。
免費 / 開源Focuses on collaborative team AI workspaces and plugins, but shares similar open-source architectural goals.
專項更強強烈專注於重視隱私的文件聊天與本地 RAG 管道，但提供較少的通用聊天 UI 功能。
免費 / 開源提供可在離線時輕鬆執行本地模型的桌面原生應用程式，但缺乏 Open WebUI 以伺服器為核心的多使用者功能。
