Mac Markdown App for AI Agent Specs

Review AI-agent specs like a PR: comment on lines, agent fixes over MCP, you accept changes.

In plain English

This Mac app is for people who write instruction files that tell an AI helper what to do. You read the file as simple text, comment on a line, and the helper sends a fix back for you to accept or reject, a bit like marking a classmate's paper. Buyers already use AI coding helpers, and they pay because those files are fiddly to review by hand. The back and forth of comments and fixes is built into the app, yet a person still does a lot. Whoever runs it focuses on how the app feels to use, talks with builder communities, and answers support questions.
