把一句話、會議紀錄或筆記變成真正基於你 Notion、Linear、GitHub、Granola 上下文的 PRD。
以 CPO 視角為文件在策略、結構、清晰度與完整性上打分，並給出可一鍵接受的行級修改建議。
直接從規格生成可點擊原型，指點即可微調元素並當天分享連結，或匯出到 v0、Lovable、Bolt、Cursor。
從文件、工單、程式碼和會議中提取上下文，再把成品推送到 Google Docs、Notion、Confluence、Linear、Jira、Slack 和 Teams。
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.
