Product Overview
WitNote 2.0.1 is a major rewrite of an existing Mac App Store app. The product remains one App Store record, but the implementation now uses a native Swift macOS workspace and a local MLX inference route.
The center of the product is still the user's Markdown files: a selected folder becomes a working knowledge space for writing, reading, conversion, and review. AI stays beside the document instead of replacing the document as the source of truth.
The bundled Qwen3 0.6B 4-bit model gives a new user a ready local starting point. Additional model downloads are optional network actions and remain subject to the source model's own license and notice files.
- Version
- 2.0.1 A major Swift-native rewrite of the existing Mac App Store product.
- Core
- Markdown workspace User-selected folders, editable documents, previews, and exports remain the center of the workflow.
- AI
- MLX + Qwen3 A bundled lightweight model supports a quick local start; other downloaded models are disclosed separately.
- Privacy
- Local-first User-selected folders, Markdown documents, and exports stay local by default. Local inference does not send writing to a hosted AI service by default; model downloads, StoreKit, and user-opened external links are explicit network actions.
Why It Matters
Each product page is written for users, reviewers, and builders: what it solves, what it does not solve, and what can be reused.
Native Mac structure
The rewrite moves the main workbench, file access, model management, settings, purchase restore, and window behavior into a Swift-native macOS architecture.
Privacy with explicit boundaries
Local files and local inference are separated from model downloads, StoreKit, and any external page the user chooses to open.
Core Experience
Markdown workspace
Choose a local folder, edit Markdown documents, preview the rendered result, and keep the source files available to Finder and other tools.
Local knowledge workflow
Folder organization, search, notes, versions, and document context make the local directory useful as a lightweight knowledge base.
MLX local AI
The native app includes a Swift MLX runner and a bundled Qwen3 0.6B 4-bit starter model for local writing assistance on supported Macs.
Reading and conversion
PDF, Word, and EPUB workflows are positioned as supporting capabilities for bringing material into Markdown, bilingual reading, notes, and export.
Release discipline
The 2.0.1 release treats package signing, model notices, clean-start behavior, IAP restore, metadata, and App Review evidence as one connected acceptance chain.
Design Principles
Keep the public promise reproducible
The product page only describes the native Mac build, bundled model, and verified workflows that the submitted package can actually reproduce.
Separate product code from model rights
MLX, Qwen3, and any user-downloaded model remain credited through package notices and source terms instead of being presented as one proprietary asset.
Make publishing part of engineering
Privacy wording, support links, purchase recovery, model downloads, package integrity, and App Store metadata are tested against the same release candidate.
Build Diary
The new WitNote diary entry explains the 2.0.1 Swift-native rewrite, local Markdown architecture, MLX model path, model-management lessons, legal boundaries, and the release checks that connect engineering to App Store publishing.
