Hey HN,In this age of agentic coding I've found myself spending a lot of time reviewing markdown files. Whether it's plans or documentation that I've asked my agent to generate for me, it seems that I spend more time reading markdown than code.I've tried a few different solutions to make it easier to read such as Obsidian however I've found their Vault system to be quite limiting for this use case and I've found TUI solutions to not quite be as friendly to read as I've wanted so I made Marky.Marky is a lightweight desktop application that makes it incredibly easy to read and track your markdown files. It also has a helpful cli so you can just run marky FILENAME and have the app open to the md file that you pointed it at. I've been using the daily over the past week and I really enjoy it so I figured I'd share it.Here's a video if you want to check out a demo: https://www.youtube.com/watch?v=nGBxt8uOVjc.I have plans to add more features such as incorporating agentic tools such as claude code and codex into the UI as well as developing a local git diff reviewer to allow me to do local code review before pushing up to git.I'd love to hear your thoughts and any feature suggestions you may have :)

Feature requests: Ability to open markdown files outside of vaults, CLI for quickly opening files, TUI (terminal user interface) version, Windows and Linux support
