Turn Gmail and Outlook into a real-time webhook API
Get granular, standardized events such as inbox.added, inbox.read, sent.added, drafts.added, spam.added, label.added and catch-all deletion events for both Gmail and Outlook.
Advanced deduplication stops the same Gmail message from firing more than once, so downstream systems never process duplicates.
Failed deliveries are retried with exponential backoff for roughly 1.5 hours, and all events are stored for 30 days so you can replay any delivery via the API.
A single REST API sends emails, lists messages, manages labels and migrates users across Gmail and Outlook with encrypted credential storage.

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.
