Proactive AI assistant and agent platform that works inline across apps, sorting email, briefing you in Slack and improving your writing everywhere.
Key features
- Proactive Inline Suggestions: Annotates text in real time wherever you write, pointing out where you could be clearer, more convincing or factually wrong without needing a prompt.
- Email Assistant Agent: Sorts incoming mail, clears clutter, follows up and pre-drafts replies in your voice using context from your calendar and connected apps, powered by Superhuman Mail.
- Customizable Grammarly Agent: Built-in Grammarly writing intelligence that learns which underlines you find useful and adjusts its feedback accordingly.
- Knowledge Checker and Daily Brief: A background researcher that searches your data sources for evidence behind claims, plus a daily report surfacing Salesforce deals, Jira tickets, tasks and meetings needing attention.

- Custom Agents and Agent Store: Build agents that trigger as you type, on a schedule or after events like a meeting ending, or add ready-made agents from Superhuman and partners.
- Many Surfaces: Works as inline underlines, a context-aware side chat, cursor actions on highlighted text, a Slack teammate you can @-mention, and a standalone Go app across desktop, browser and mobile.
