A general-purpose AI agent that executes tasks, not just answers them
Give the agent a goal and it plans the steps, chooses tools, and works through the task in a cloud environment without constant supervision.
Produces finished artifacts such as slide decks, functional websites, small games, and formatted documents rather than raw text.
Runs broad, multi-source investigations and compiles the findings into a structured report.
Generates images, video, and music as part of a larger task or as standalone outputs.
An AI email assistant that drafts, summarizes, and perfects your messages in place
Turn a handful of keywords or bullet points into a full, sendable email, and generate replies framed as positive, negative, or neutral depending on the situation.
Condense long email chains into the key points so you can catch up fast and respond without re-reading every message.
The assistant rewrites and corrects your message for grammar, spelling, and phrasing before you hit send.
Follow-up suggestions combined with open and click tracking tell you which threads are urgent, and the assistant can draft the follow-up for you.
