What does Mainframe do?
Cobot was an AI agent platform built by Mainframe that brought multiple AI agents into a single shared workspace where teams could accomplish tasks together. Launched in early access beta in early 2025, it aimed to accelerate team productivity by letting you collaborate with AI agents side by side. Think of it as a virtual room where you and your team could assign tasks to different agents, have them work simultaneously, and manage the results in one place. The tool was designed to make AI feel less like a solo assistant and more like a collaborative team member.
Cobot worked by providing a shared space where you could interact with multiple AI agents at once. Instead of switching between different AI tools or chatbots, you could bring agents together to handle different parts of a project. The exact mechanics aren't detailed in the shutdown announcement, but the core idea was to create a collaborative environment where humans and AI agents could work on tasks in parallel. It was part of Mainframe's broader vision of "generative computing" — new ways to interface with AI.
Unfortunately, Cobot is being shut down. As of November 2025, billing has been paused, and the service will end on November 30, 2025, after which all user data will be deleted. The team at Mainframe decided to focus on a different, more specific problem. For the teams that tried Cobot during its beta, it offered a glimpse into a future where AI agents work alongside humans in a shared digital space. If you were looking for a tool to coordinate multiple AI agents for team projects, Cobot was an interesting experiment — but it's no longer available for new users.
