SenderStack

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.

AI email reply and compose

Generate replies, draft new messages, and produce multiple phrasing options from a Gmail sidebar without breaking your workflow.

Multi-model AI chat

Talk to several well-known AI models in one interface and pick the one that fits each research, writing, or summarization task.

Chat with PDFs and web pages

Upload documents or point the assistant at a page to extract answers, summaries, and key points instead of reading everything yourself.

Trainable AI personalities

Create custom personas for professional, casual, sales, or support writing and train them on your own tone so output matches your voice.
