“We stopped maintaining a separate Notion mirror of every dashboard. Comma is now the review surface, and the actual report is the artifact. Reviews are anchored to the cells.”
“The MCP integration is unreasonably good. Claude writes the report, posts it, and resolves my feedback. I review one link.”
“I used to lose 20 minutes per readout to screenshot-and-paste. Now I share one link and reviewers comment directly.”
One continuous take. Real product, no mockups: drop in an HTML report, mark a line, drop a comment, watch a teammate drop their reply live, then hand out a link.
