EveryTool4U Markdown Preview

Write Markdown beside a live browser preview and export HTML.

A free browser editor with Markdown source on the left and rendered output on the right. Formatting shortcuts, tables, task lists, and fenced code blocks help you check README files and short drafts. Copy or download the resulting HTML without an account. Rendering happens in your browser; the tool does not save your text, so keep a separate copy of your work.

Caliu

Keep Markdown notes offline with tags, sync, and source editing.

A local-first notes app for Mac, iPhone, iPad, and the web, with Android available in beta. Write in a rich inline editor or switch to raw Markdown, organize notes with nested tags, and work offline. The Mac app can connect a folder of plain Markdown files and pick up external edits. Core writing, tags, sync, and Markdown export are free. Caliu Pro adds server-backed version history, API access, and additional export formats; history needs an internet connection. Pro PDF export is available on Apple apps, while HTML export also works on the web.

Header

Keep Markdown notes, meeting minutes, and research together on your Mac.

Meeting transcription can run locally on macOS 26 or with an optional Whisper model; earlier systems and some languages may use Apple's servers.
