Built for writers

Not a code editor with a chat panel. Margink is designed for prose.

Contextual AI

Your assistant reads your project structure, style notes, and previous chapters.

No more copy-pasting context into every conversation. Margink automatically detects your project, loads relevant files, and builds a briefing that follows your writing session.

Markdown native

Visual styling while preserving raw markdown underneath.

Bold, italic, and headings are rendered visually as you type, but the file is always plain text. No proprietary format, no lock-in. Works with any other markdown tool.

Multi-tab

Multiple files, each with its own conversation and context.

Work on chapter 3 while referencing your worldbuilding notes in another tab. Each tab has independent chat history and AI context, persisted between sessions.

Themes

Four atmospheres crafted for long writing sessions.

Writer's Desk (warm dark), Parchment (warm light), Midnight (cool dark), and Desert (earthy warm). Each with carefully tuned contrast ratios for readability.
