An AI email assistant that writes replies and full messages inside Gmail, Outlook and Zendesk
Turn a short phrase or bulleted list into a complete, professional email, including cold outreach, applications and follow-ups.
Ghostwrite reads the incoming message and drafts a contextually appropriate full reply in a single click.
Switch between formal, friendly, concise and persuasive registers so the same content fits different recipients and situations.
Text is corrected for spelling, grammar and clarity as it is generated, so nothing goes out with obvious mistakes.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
