Nota6 vs PicToolbox

Reader-first Markdown app for the AI era — with a built-in Reference Library so it's useful the moment you open it. BUILT-IN LIBRARY (12 references, all offline) The welcome screen has a "Browse Library" button. Tap it and you have 12 curated documents available immediately, in English and Simplified Chinese: • Markdown / GFM syntax references • Mermaid Diagram Gallery — 10 diagram types (flowchart, sequence, class, state, ER, gantt, pie, mindmap, timeline, git graph), each with source + rendered output • KaTeX Math Reference — symbols, operators, matrices, common formulas • Code Highlighting Gallery — Swift, Python, TypeScript, Go, Rust, SQL, and more (190+ languages bundled) • Reading AI-Generated Markdown — four shapes of agent output and how to read each • CLAUDE.md & AGENTS.md spec — how AI-instruction files work • README Patterns, Design Doc & RFC Patterns • Nota6 Tips & Tricks, iPad Keyboard Shortcuts, Themes Showcase These aren't placeholders — they're useful reading material for anyone who works with AI coding assistants and the .md files they produce. WHAT MAKES IT DIFFERENT FROM A BROWSER • Mermaid diagrams, KaTeX math, syntax-highlighted code, all rendered offline. No network requests during rendering. Safari Reader can't do Mermaid; Nota6 can. • Auto-refresh on file change with smart scroll anchoring: when an external editor rewrites the file, the preview re-renders in place and stays at the same heading even if the document length shifts. • Open files from anywhere via the system share sheet, Files, iCloud Drive, or the "Open in Nota6" action. iOS-NATIVE INTEGRATIONS • Shortcuts / App Intents: "Open Markdown File" and "Export Markdown as HTML" are first-class Shortcuts actions. Automate from Siri or your iPad keyboard. • iCloud sync: your theme, font, width, and Custom-theme colors follow you across iPhone, iPad, and Mac. • Workspace full-text search (⌘⇧F) across an entire folder of .md files. • Bookmark self-heal: if AI tooling renames or moves files in your workspace, Nota6 reattaches by content fingerprint instead of breaking. • Deep links: nota6://open?path=...&heading=... jumps to a specific heading. READING EXPERIENCE • Quick Edit: switch to Source, correct raw Markdown, and save with Command-S on a hardware keyboard. Nota6 preserves the original encoding, BOM, and line endings, and warns before overwriting external changes. • 5 themes: GitHub · Paper · Notion · Terminal · Custom. Custom lets you pick body + monospace fonts and 4 colors (background, text, heading, code block) right inside the app. • 4 font sizes, 3 reading widths, Light / Dark / Auto appearance. • Outline panel with live filter and scroll-synced active heading; floating breadcrumb when the outline is closed. • Per-file reading-progress dots in the workspace sidebar. • Click-to-zoom for Mermaid diagrams and images; long-press to Copy or Save as PNG. iPAD HARDWARE KEYBOARD Full shortcut set: ⌘O · ⇧⌘O · ⌘F · ⌘P · ⌥⌘O · ⌘R · ⌘[ / ⌘] · ⌘W. Press-and-hold ⌘ for the discoverability HUD. EXPORT PDF or self-contained HTML via the system share sheet — straight to Files, Mail, Slack, Notion, or any other destination. PRIVACY No analytics. No third-party SDKs. No network requests unless the document itself references remote images. Rendering libraries (KaTeX, Mermaid, highlight.js) are bundled offline. English + Simplified Chinese.
