Switch between Markdown and Preview in the same tab.

Your files, close at hand.

Open one folder or several. The sidebar keeps their files in view and updates as things change on disk.

Switch without losing your place
Tabs keep their own edits, selection, and scroll position. Move any tab to a new Mac window.
Write in Markdown
Switch to Preview to see headings, tables, fenced code, and local images. Open images in their own tabs.
Edit ordinary text files
Use syntax coloring, line numbers, and regex find and replace. Textley preserves supported file encodings and line endings.
