Show HN: Keen Bean – Mac meeting notes that draft the spec while you talk

Keen Bean is a Mac application that automatically generates meeting artifacts—including task lists, decisions, draft specifications, and diagrams—in real-time during calls without requiring a recording bot or external servers. Unlike traditional meeting bots, it processes audio locally on the user's Mac and keeps all content private, storing outputs as editable Markdown and JSON files that users can export to tools like Obsidian. The app targets individual consultants, founders, and knowledge workers who need to produce documentation from meetings without sharing recordings or relying on shared workspace infrastructure.
