What is it?

Tinta is a Markdown and Mermaid viewer for Windows, written in native C++ and rendered with Direct2D and DirectWrite. It ships as a single executable of about 2.5 MB that starts quickly and needs no installer, so it works well as the default app for .md and .mmd files when you mainly want to read documentation and diagrams.

Beyond viewing, it includes an edit mode with a side-by-side preview, search and find-replace, a table of contents, and a folder browser. Mermaid diagrams are rendered natively across 22 diagram families, and LaTeX math is supported. Documents can be exported to HTML, DOCX or PDF, and PlantUML diagrams render through a PlantUML tool the user already has installed.

Tinta offers 10 themes, tabbed windows, review annotations stored as HTML comments in the file, and a UI available in several languages. It can be installed from the Microsoft Store, via winget or Scoop, or run as a portable exe.
