The AI email assistant that sorts your inbox and drafts replies in your voice
Incoming mail is sorted into categories like To Reply, Newsletter, Cold Email, Calendar and Notification as it arrives, using default rules or categories you define yourself.
Emails that need a response get a draft written in your tone and referencing your real calendar availability and CRM context, ready to review and send.
Stop cold outreach from ever reaching the inbox, see which newsletters you never read, then unsubscribe and archive them in bulk.
Dashboards reveal who emails you most, which senders dominate your inbox and how your habits change over time so you can act on it.
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.
Industry standard collaborative whiteboarding with massive template libraries, but less streamlined for rapid AI diagram generation.
