Compress notes into shorthand. Build custom dictionaries, study CompTIA packs, and abbreviate selected text anywhere. Margin turns walls of text into clean, student-style shorthand — instantly, and entirely on your device. Paste your notes and watch them compress in real time: "because" becomes b/c, "without" becomes w/o, "increases" becomes an up arrow, "the/a/an" filler disappears, and long unknown words lose their inner vowels (development becomes dvlpmnt). Capitalization is preserved, so "BECAUSE the Government" becomes "B/C the Gov." BUILD YOUR OWN DICTIONARIES Margin isn't a fixed list. Create your own toggleable dictionary packs, add unlimited rules (word to abbreviation), and strip filler words. Mix and match packs per subject. Export any pack as a file and share it with classmates, or import one they made. READY-MADE STUDY PACKS Ships with 400+ rules out of the box, including a full CompTIA Network+ pack that tags protocols with their default ports as you write (SSH becomes SSH [22], HTTPS becomes HTTPS [443], DHCP becomes DHCP [67/68]), maps OSI layers (Network layer becomes L3), and keeps acronyms like TCP, OSPF, and VLAN intact. Plus a general academic pack for essays, lectures, and meetings. ABBREVIATE ANYWHERE Highlight text on any website, right-click "Abbreviate & Copy," and the shorthand is copied straight to your clipboard. Great for condensing readings into notes. PRIVACY FIRST Your notes never leave your device. No analytics, no tracking, no data selling, and it's completely free. Dictionaries sync through your own Chrome account. That's it. Built for students, note-takers, and anyone who writes faster than they can type. Free and open — if it helps your studies, you can support development on Ko-fi.
