Open Markdown Files Locally — Asterive

Open and render Markdown files locally in Asterive without uploading the source or creating a note until you explicitly import it.

Asterive opens .md, .markdown, .mdown, and .mkd files in a local browser viewer.

The Markdown source remains in the current tab and is not uploaded or saved as a note automatically.

Installed compatible desktop PWAs can register Asterive as a Markdown file handler.

Import is a separate explicit action that opens a note draft for review.
