Hey Product Hunt,

I built MarkView because Markdown is quietly becoming a default document format in the AI era.

ChatGPT, Claude, Cursor, and Claude Code all produce Markdown constantly: specs, notes, plans, documentation, tables, and handoff docs. That works great for technical people, but it gets awkward when you share an .md file with someone who is not living in GitHub or an IDE all day.

Raw Markdown is fine for simple notes. But once a document has tables, code blocks, task lists, or diagrams, it gets hard on the eyes. The syntax starts competing with the content.

That leaves a weird gap when you want to send someone a Markdown document and tell them how to read it. VS Code, Obsidian, and Notion are great tools, but they are a lot to install just to open one file. Typora is a nice option, but it is paid. Markdown preview websites can work, but now someone has to upload a file or paste content into a form, which adds friction and may not be appropriate for private docs.

I wanted something simpler: a free, focused viewer I could send along with a Markdown file, without asking someone to install a whole developer workspace, pay for an editor, or copy their document into a website.

MarkView is that simple answer: a native desktop app for opening and reading Markdown files cleanly, like Acrobat Reader does for PDFs.

What it does:

- Opens .md files by double-click, drag-and-drop, or File > Open

- Renders tables, code blocks, task lists, images, front matter, and Mermaid diagrams

- Works on macOS, Windows, and Linux

- Keeps files local, with no account and no upload step

It is a viewer, not an editor. The goal is simple: make Markdown documents easy to send to anyone.

I would love feedback from people who share Markdown files with clients, coworkers, students, or less technical teammates:

What would make a Markdown viewer trustworthy enough for you to send along with a file?
