Show HN: Tufte Editor – Local Markdown Editor with Tufte CSS Live Preview A split-pane Markdown editor that renders live preview with Tufte CSS. Sidenotes, margin notes, epigraphs, full-width figures, and BibTeX citations with autocomplete — all in standard Markdown extensions. Documents are .md files on disk. Images are regular files. Exports to standalone HTML with Tufte CSS baked in — my use case is writing essays and uploading them directly to my personal site. Zero dependencies, no npm install, no accounts, no build step. Just `node server.js`. ~7 files total. Full disclosure in the README: I'm a researcher, not a JS developer, and the code was AI-generated. Contributions and code review welcome. https://ift.tt/izTJvIY February 15, 2026 at 05:22AM
