Goodline: Markdown Writer

Goodline gives your writing room to breathe. Open a Markdown document and focus on the words, with formatting tools, an outline, and a clear view of your work. Write in plain-text Markdown files you can keep in Files or iCloud Drive. Work with tables and images, find your way through long drafts, and export your writing. Your documents stay yours. Turn Markdown into slides with Marp editing and a live preview. Add Mermaid diagrams in fenced code blocks, view speaker notes, and prepare local slide images and presentation packages. Your original Markdown stays editable. Use Listen to hear a document or selected passage. Choose an installed Apple system voice, preview it, adjust the speed, and pause, resume or stop. Goodline prefers a matching-language enhanced or premium voice when one is installed. Listen uses no paid speech API; voice quality depends on your installed voices. Try writing features free for 14 days by confirming the free in-app purchase. A separate one-time unlock keeps editing available afterward. There is no subscription or automatic charge. Reading, copying and exporting existing documents remain available without the unlock. Some features depend on system version, device capabilities, Apple Intelligence availability and iCloud settings.
