專為團隊打造的協作式收件匣與郵件管理
多人可處理同一收件匣，擁有清晰的指派、內部狀態與誰在回覆什麼的可視性。
直接在郵件串中討論並準備回覆，讓上下文不脫離原郵件，也不遺漏任何人。
可將任意郵件轉為指派任務，並查看每位同事今天、明天與下週的工作安排。
透過規則、規則範本與工作流自動化重複的路由、標籤與跟進工作。
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。
提供極速的鍵盤導向電子郵件管理功能，但缺乏 Missive 以團隊為核心的共用收件匣與內建內部聊天頻道。
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。
專項更強Automates email triaging and executive scheduling effectively, but is structured as a virtual assistant rather than a collaborative team inbox.
