Margin — Notes Abbreviator

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 ↑, "the/a/an" filler disappears, and long unknown words lose their inner vowels (development → 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 → 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 → SSH [22], HTTPS → HTTPS [443], DHCP → DHCP [67/68]), maps OSI layers (Network layer → L3), and keeps acronyms like TCP, OSPF, and VLAN intact. Plus a general academic pack for essays, lectures, and meetings. — ABBREVIATE ANYWHERE (Premium) — Highlight text on any website, right-click "Abbreviate & Copy," and the shorthand is copied straight to your clipboard. Perfect for condensing readings into notes. — FREE vs PREMIUM — Free: full editor, build dictionaries, and run up to 2 active dictionaries at once.
