# Nota6 — Nota6 > Nota6 (iPhone/iPad app by 笑天 刘.) - Source: https://appshunter.io/ios/app/nota6/id6771324417 (this page in markdown: same URL + `.md`) - Developer: [笑天 刘](https://appshunter.io/developer/1845977493) - Category: Utilities, Productivity - Price: Free - Age rating: 4+ - Requires: iOS 17.0 · 11 MB - Languages: American English, Chinese (Simplified, China) - Released: 2026-05-27 - Data updated: 2026-07-20 - User reviews in markdown: https://appshunter.io/ios/app/nota6/id6771324417/reviews.md ## What is Nota6? 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. ## Version history (last 5 releases) ### 1.7.0 — 2026-07-16 1.7.0 adds Quick Edit and a smarter workspace sidebar. • Switch to Source, make a small Markdown correction, and save with Command-S on a hardware keyboard. • Nota6 preserves the original text encoding, BOM, and line endings. • Unsaved-change prompts protect edits when switching files or leaving Source. External disk changes require explicit overwrite. • Opening a file inside the workspace now expands and reveals it automatically. Files elsewhere appear as “Outside Current Folder” with an action to browse their containing folder. Built-in Library and sample documents remain read-only. ### 1.6.4 — 2026-06-04 1.6.4: • Pin files: long-press a file in the workspace sidebar and choose Pin. Pinned files appear in a "Pinned" section at the top of the sidebar, so the documents you reference most are one tap away. • Simplified Chinese localization: the app interface is now fully localized in Simplified Chinese on zh-Hans devices. ### 1.6.3 — 2026-06-03 1.6.3: • YAML frontmatter card: a leading --- ... --- block (title / author / date / tags) now renders as a clean header card instead of raw text. (The Open-in-Editor and sidebar Pin features added in 1.6.3 are macOS-only.) ### 1.6.2 — 2026-06-02 1.6.2 is a stability and robustness update: • Code containing a dollar sign (like "echo $5", or a fenced code block) now displays exactly as written, instead of being misread as a math formula. • Large files no longer freeze the app — files over 25 MB are declined with a clear message. • Markdown saved in legacy Chinese encodings (GBK / GB2312) now opens correctly. • Error messages are localized (English + Simplified Chinese). ### 1.6.1 — 2026-05-29 1.6 ships a built-in Reference Library — Nota6 is now useful the moment you open it, with no external files required. NEW: BUILT-IN LIBRARY • 12 curated documents bundled inside the app (English + Simplified Chinese), available offline • Markdown / GFM syntax references • Mermaid Diagram Gallery — 10 diagram types with source + rendered output • KaTeX Math Reference — symbols, matrices, common formulas • Code Highlighting Gallery — Swift, Python, Go, Rust, SQL, and more • Reading AI-Generated Markdown — strategies for handling agent output • CLAUDE.md & AGENTS.md spec, README patterns, Design Doc patterns • Nota6 Tips, iPad Keyboard Shortcuts, Themes Showcase • Entry points: a "Browse Library" button on the welcome screen, and a "Library" row at the top of the workspace sidebar ALSO IN 1.6 • swift-markdown parser (Apple's official AST-based CommonMark + GFM parser) — dense LLM-generated documents now parse correctly • View Source toggle (⌃⌘S on iPad) between rendered preview and raw markdown • Sidebar polish on iPad: capsule filter field, focus auto-clear when a file is selected • Numerous rendering and stability improvements ## More apps by 笑天 刘 - [失败的艺术](https://appshunter.io/ios/app/id6759132313) - [见证者教练](https://appshunter.io/ios/app/id6766876720) All apps by 笑天 刘: https://appshunter.io/developer/1845977493 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
