AI email replies, multi-model chat, and workflow automations in one workspace
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.

Automate your email with AI
A conversational agent that organizes your inbox, identifies what matters, drafts replies, writes scheduling emails and runs multi-step workflows from a single prompt.
Plain-language AI filters and scripts that automatically label, archive, star or sweep messages so you reach inbox zero faster.
Ask questions in natural language and search across your own messages — or your whole team's emails and attachments — to get answers rather than links.
Shared threads, private comments, assigned next steps and shared labels give a team one live view of important conversations.
