SenderStack is an AI writing and email productivity platform available as a Chrome extension and a web workspace. It drafts and replies to email in your own voice, lets you chat with multiple AI models, translate and summarize documents, and build simple automations that remove repetitive busywork from your day.
Generate replies, draft new messages, and produce multiple phrasing options from a Gmail sidebar without breaking your workflow.
Talk to several well-known AI models in one interface and pick the one that fits each research, writing, or summarization task.
Upload documents or point the assistant at a page to extract answers, summaries, and key points instead of reading everything yourself.
Create custom personas for professional, casual, sales, or support writing and train them on your own tone so output matches your voice.

智慧收件匣與 Priority 會突顯重要聯絡人郵件，並將電子報與通知歸類收納，讓主收件匣保持清爽。
AI 助理可尋找、摘要並處理收件匣中的任任郵件，AI 寫作助理協助撰寫郵件，Auto-Drafts 還能預先草擬回覆。
可翻譯收到的郵件、快速取得長郵件串摘要，無需逐行閱讀即可抓住重點。
支援共用草稿、加入私密留言、指派郵件負責人並追蹤進度，方便與同事協作。
具備更強大的團隊協作功能（含共用郵件匣與內部聊天），但對獨立消費者的 AI 寫作功能著墨較少。

Great at summarizing multi-message email threads and extracting action items, but offers fewer overall customization settings than Spark.
