The phone layer that gives every AI agent a real device
Streamed, scalable Android devices that agents control through an API, removing the need to maintain physical handset labs.
An open layer that connects any AI agent to a phone, with strong published results on the AndroidWorld benchmark.
Describe the outcome you want; the agent reads the screen and decides which taps, swipes and text entries to perform.
Run many phones in parallel for testing, data collection or high-volume workflows.

Open-source workspace to build, deploy and govern AI agents
Create agents by describing them in Chat, arranging blocks on a visual canvas, or writing code and CLI commands, and deploy the result without rebuilding it.
Sync and auto-update documents from Notion, Google Drive, Confluence, Slack, GitHub and SharePoint so agents ground answers in current company knowledge.
Agents read and write structured data in Sim Tables and keep files and artifacts organized in one shared store across runs.
Trace every agent run block by block with success rate, latency, execution cost and failure details for debugging and reporting.
