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.

The AI productivity suite with agents, email, and docs that work wherever you do
Superhuman Go brings AI agents into the tools and tabs you already use, with inline suggestions and context-aware chat.
Auto drafts, split inbox, auto labels, and auto archive keep your inbox manageable with minimal manual filing.
Collaborative documents that hold text, tables, data, and workflows in one connected surface.
Describe what you need in chat or use a visual builder, then share agents with teammates or a company directory.
