Profile

Hi HN,Around summer/fall of 2025, I started using 'plan mode' quite a bit more. When I would cmd+click into a newly created markdown plan, macOS would open Xcode. This was slow, didn't have native rendered viewing, the list goes on. I started working on a markdown viewer to easily open, review plans before I sent Claude on their way. The Markdown Viewer was born! It came from inspiration from the great Preview Mac app.For Christmas our family got a Bambu A1 3D printer (fantastic btw!) and I wanted to easily preview 3d files before opening/sending to the printer, etc. Well, I started up a 3d viewer. Yaml, CSV, Text viewers all followed.As a responsible engineer, I started seeing patterns, so

Simple Viewers – Tiny native macOS file viewers is positioned in show hn launch, a segment that rewards a clear, focused offering.

The company is listed at the Show HN launch stage of development.
