The AI writer that verifies facts against real sources before it writes a single sentence
Retrieves real sources, tests every claim against them, and discards what does not hold up so the writer only works from verified material.
Every source is clickable, with verified and filtered counts shown so you can see exactly what was kept and what was cut.
Post, blog, in-depth blog, case study and white paper, each with its own enforced length target and structure.
Voice, audience, positioning, proof points and a banned-words list are applied at generation, and you can watch output change when you change them.

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.
