Coluracetam — Markdown Reader

Quick Look preview & editor

Only for Mac

$4.99

Mac

Press space on a Markdown file in Finder — and read it as a rendered document. macOS has never known what to do with a .md file. Coluracetam fixes that at the system level: a Quick Look extension renders your Markdown the instant you hit space — GitHub-styled, light and dark, no app launch — and rendered thumbnails make a folder of notes look like notes instead of a wall of gray syntax. Open the app itself and it is the same rendering, byte for byte, with everything a real Mac document app should have. READ, WRITE, OR BOTH Switch between a clean rendered preview, a split view that renders as you type, and a distraction-free source editor. Selection, Find (with match counts), and printing work the way Mac apps should, in every mode. AT HOME ON THE MAC • Quick Look: rendered Markdown previews and thumbnails right in Finder — press space, no app launch • Live preview with real text selection, clickable links, and a copy button on code blocks • Split editing — the preview follows every keystroke • Line numbers with click-and-drag line selection, and Go to Line (⌘L) • Native Find in both the preview and the source (⌘F) • Tabs, printing, and PDF/HTML export • Right-click a folder in Finder to create a new document there, or turn any selected text into a document via Services • Shortcuts support: Create Markdown Document, with folder and initial content • Keep on Top, window opacity, and quick size presets for floating a note over your work • Files stay yours: plain Markdown on disk, edited in place, with external changes reloaded live FAST BY DESIGN No web view, no bundled browser — just native AppKit text rendering. Parsing runs off the main thread and layout is viewport-lazy, so multi-megabyte documents open in a blink, scrolling stays smooth, and typing never lags. PRIVATE BY DEFAULT No accounts, no telemetry, no network access. Coluracetam collects nothing.

PDF import — open any PDF and it becomes a Markdown document. • Open a PDF from Finder (or drag it onto the app) and it converts instantly, headings and links intact • File → Import PDF… for the same flow from inside the app • Japanese and other CJK documents supported • Scanned, image-only PDFs are detected and refused with a clear explanation instead of importing garbage Conversion runs entirely on-device — nothing ever leaves your Mac.
