What is Kit (formerly ConvertKit)?
Kit handed page-building to an agent, then went back to cleaning up the subscribers list
The Kit MCP crossing from reading a creator's list to building and editing landing pages remains the defining recent release. Since then the work has been ordinary interface repair on the subscriber surface: the Subscribers page was reorganised around search and filtering, and bulk actions became a floating menu that follows the scroll instead of sitting at the top of the list. Creator Network connection requests and custom favicons round out the window.
What is Gumloop?
Gumloop 13.1 lets live artifacts drive agents through the SDK and opens outputs in Office.
Gumloop ships a numbered release every few days. In October it gave agents a real browser (12.0), agent-owned secrets, team sharing and embeddable AI artifacts, then 13.0 rebuilt the agent harness for longer work and added organization-wide evaluations. 13.1 lets scripts in live artifacts message, create and list agents, artifacts, skills and teams through the Gumloop SDK, opens agent-made files in Google Workspace or Microsoft Office, and lets agents on a call run long tasks in the background while they keep talking.

Kit handed page-building to an agent, then went back to cleaning up the subscribers list
◆ Current state
The Kit MCP crossing from reading a creator's list to building and editing landing pages remains the defining recent release. Since then the work has been ordinary interface repair on the subscriber surface: the Subscribers page was reorganised around search and filtering, and bulk actions became a floating menu that follows the scroll instead of sitting at the top of the list. Creator Network connection requests and custom favicons round out the window.
◆ Where it's heading
The Kit MCP is the axis, and it has already made its jump — from read-and-analyze in May to producing the published artifact in July. What follows is consolidation: the manual surfaces are being tidied so the things an agent can do and the things a creator does by hand sit on comparable footing. Nothing in this window extends the MCP itself, which makes the current period a pause rather than a redirection.
◆ Prediction
Expect the MCP surface to extend to more of the artifacts Kit publishes now that landing pages have proven the pattern. The subscriber-page work reads as a finished cleanup rather than the start of a larger rebuild.
Gumloop
7.5MKT AUTO
Gumloop 13.1 lets live artifacts drive agents through the SDK and opens outputs in Office.
◆ Current state
Gumloop ships a numbered release every few days. In October it gave agents a real browser (12.0), agent-owned secrets, team sharing and embeddable AI artifacts, then 13.0 rebuilt the agent harness for longer work and added organization-wide evaluations. 13.1 lets scripts in live artifacts message, create and list agents, artifacts, skills and teams through the Gumloop SDK, opens agent-made files in Google Workspace or Microsoft Office, and lets agents on a call run long tasks in the background while they keep talking.
◆ Where it's heading
The product is moving from building agents to operating them at org scale, and artifacts are turning into small apps that can control agents themselves. Model access is also being made easier to manage, with families, deprecation dates and fallback visibility.
◆ Prediction
Expect more of the SDK exposed to artifacts and further evaluation and Insights controls at the usual weekly pace; the entries don't show pricing changes.
