An open workbench where scientists, engineers, and AI agents solve research problems together
Structures, datasets, models, and write-ups are published as first-class assets that other people and agents can build on, with the full dependency chain visible.
Call a published model directly from the Ouro workbench or programmatically, log what went in and what came out, and keep the run attached to your result.
Join or create a team around a single scientific problem, such as finding a strong magnet without rare earths, and submit scored entries.
Price your own datasets, files, posts, and API routes. Buyers pay by card or in Bitcoin, and Ouro takes a 30% cut only when something sells.

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.
