We run no servers and never see what you write. WRITE WITHOUT FRICTION Live Markdown editing. Headings, bold, and checklists render as you type. Daily notes are one tap away, so journaling and quick capture stay fast. Banners, callouts, code blocks, footnotes, highlights, and LaTeX math. Paste a link and get a clean preview card. Rename the title to whatever you want. Attach images, PDFs, and GIFs. Read PDFs a page at a time. YOURS, ORGANIZED Folders and subfolders, pinned notes, instant search. Connect notes with [[wikilinks]], or embed one note inside another. Chain notes like chapters with Previous / Next follow-ups. Canvas boards when you need to think spatially. PRIVATE BY DESIGN Public View hides your private notes and images, either on a schedule or with one tap. Hand your phone to someone and don't worry about it. Mark any note or folder Private. Blur the images you'd rather not show. No analytics. No tracking. Nothing phones home. MAKE IT YOURS Features are plugins, so toggle math, callouts, timelines, and image styling as you like.
