An all-in-one AI super assistant for professionals and enterprises
A single chat interface that gives access to a broad catalog of frontier language models, with the ability to switch or compare models per prompt.
Describe a goal and the agent builds toward a deliverable such as a multi-page website, a slide deck, an app or a research report, using parallel sub-agents for larger jobs.
A persistent cloud environment for self-improving agents that can keep running scheduled or continuous work, such as monitoring and fixing bugs.
Creation tools for AI avatars, synthesized voice and generated video, covering marketing and presentation content alongside text work.

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.
