Markup vs Compare Text

Markup reads and edits your Markdown beautifully — and it works with the folder of notes you already have, on your iPhone and iPad. POINT IT AT YOUR FOLDER — OR A GITHUB REPO • Open any folder of .md files from iCloud Drive or Files — the same vault you use on your Mac. Nothing to import, no lock-in. • Open a GitHub repo as a vault and read the whole thing offline. • Open several vaults and switch between them. READ LIKE A PAGE • High-fidelity rendering: syntax-highlighted code, LaTeX math, Mermaid diagrams, tables, task lists, and GitHub-style callouts. • Light / Dark / Sepia themes, adjustable text size and width, Dynamic Type. • Wikilinks, backlinks with context, a per-document outline, and tags. FIND ANYTHING • Full-text search with tag: and path: filters; fuzzy Quick Open. EDIT WITH EASE • A focused Markdown editor with smart lists, auto-closing brackets, table formatting, and inline [[wikilink]] and #tag autocomplete. • Insert images straight into your vault. Export or share as PDF, HTML, or Markdown. iPAD • Open documents in tabs; edit with a live rendered preview beside the source. • Hardware-keyboard shortcuts. HTML, TOO • Open and read .html and web bundles, with scripts off by default for safety. PRIVATE BY DEFAULT • No account required, no telemetry, no tracking. Your notes stay on your device and your iCloud. Signing in to GitHub is optional and only used to fetch the files you ask for. English and 简体中文, switchable in-app.

Sometimes you just need to know what changed. Maybe you tweaked a paragraph and want to see exactly what's different. Maybe someone sent you a "slightly updated" contract. Maybe you're staring at two config files that are supposed to be identical but clearly aren't. Compare Text does one thing well: it puts two pieces of text next to each other and shows you what's different. Deleted bits turn red on the left, new bits turn green on the right, and a small counter tells you how much changed at a glance. It works on anything you can paste or open — plain text, code, JSON, emails, contracts, notes. A few things that make it nicer to use: • Paste straight from your clipboard, or open a text file • Ignore case or extra spaces when those don't matter to you • Wrap long lines so nothing runs off the edge • Line numbers, so it's easy to say "look at line 12" • Not sure where to start? Tap Sample to see it in action And it stays with you. No account, no ads, and your text never leaves the phone — the comparison runs right on your device, even offline. It's the same Compare Text tool people use on the web, just sized to fit in your pocket.
