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.
A personal writing workspace for the book only you can write
Start from author and book interviews, spoken thoughts and selected writing so your manuscript is grounded in your own experience, purpose and intended reader.
Get help shaping outlines, chapters and research trails while keeping every change open to your own review and approval.
Work in a browser editor with chapters, notes beside your draft, and a wording review that flags patterns for you to consider.
See separate states for voice, originality, accuracy and continuity, presented honestly as review signals rather than measured scores.
