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.
