Build, deploy, and govern production-ready agentic AI workflows
A visual canvas where retrieval, branching, tool calls, human review, and model steps form a visible, testable execution path you can debug and hand off.
Create agents through chat or manual configuration, give them skills, tools, and knowledge, then ship them as apps, embeds, or reusable nodes inside workflows.
Build repeatable ingestion pipelines for documents, sites, and drives, with extraction, cleaning, chunking, indexing, and retrieval testing before you go live.
Install model providers, tools, data sources, and MCP integrations once and reuse approved plugins across every app in the workspace.

Voice-first AI assistant that runs your Google Calendar
Dictate meetings, reminders and task updates in natural speech and let the assistant translate them into Google Calendar changes without manual form filling.
Connect your Google Calendar so new voice-created events and edits land in the same calendar you already rely on across devices.
Set priorities and targets for the week ahead, then track progress as the days pass so long-running projects stay on schedule.
A pie-chart style breakdown of your day shows how hours are distributed across activities, making time leaks easy to spot.
