For more than ten years, I've done 100% of my writing in Emacs, and I've used Claude Code to build all kinds of Rube Goldberg architecture to support my thinking, writing, research, and personal knowledge systems, including an org-mode exporter that outputs Emacs org-mode to Markdown that Astro can render.
I built a writing streak visualizer, multiple writing tracker variants, and a writing-momentum app: tools that make the invisible parts of writing, consistency, drift, momentum, avoidance, visible enough to act on.
I built Prolific, a writing momentum system with command-line check-ins, publishing workflows, and native macOS Swift popups that ask whether I'm actually doing creative work or just cleverly avoiding it. Every 10 to 20 minutes, a floating window appears on my screen with single-keypress interaction, so it takes about one second to respond. It also runs morning check-ins, pomodoro work sprints during work sessions, and end-of-session reflections to close the day.
For rapid idea capture, I made h3-workflowy, a terminal-based outliner inspired by Workflowy: full-screen, auto-saving, and keyboard-driven, with undo/redo, drag reordering, and clipboard-friendly exports, so I can capture thoughts fast and shape them later.
