锦囊AI vs CodeHouse

JinNang runs entirely on your iPhone — your conversations never leave the device. No account, zero data collection. • On-device inference: chat with no network connection (internet is only needed to download models) • A lightweight model is built in; download 7B / 9B-class models for more capability • 11 device tools: calculator, date/time, files, system, battery, translate, Safari, clipboard, reminders, location, contacts • LaTeX math rendering, knowledge base Q&A, and Gomoku / Chess with AI commentary • Tunable context window, temperature, thinking budget, and memory profile • Sampling follows each model's official recommendation (Qwen3 / Qwen3.5 / DeepSeek-R1 / VibeThinker) • Privacy by design: no tracking, no data collection — your data stays on your device • Requirements: tested on iPhone 15 Pro Max (8GB RAM); 12GB+ devices have more headroom for large models. • Pro unlocks 4B / 7B / 9B-class models, the chess coach, parameter tuning, and custom prompts.

CodeHouse is an offline encrypted vault secured by FIDO2 hardware security keys (YubiKey). SECURITY FIRST • Hardware-grade encryption: private keys never leave your security key; all cryptographic operations happen inside the key's secure chip • Fully offline: no accounts, no cloud — your data stays on your device • No backdoors: without your key, the vault cannot be opened — not even by us. That is the point • Layered protection: vault PIN + key FIDO PIN + physical touch, all required • Brute-force proof: the key's chip enforces a hardware PIN retry counter and locks itself FILE MANAGEMENT • Encrypt any file: documents, photos, videos, audio • Folder hierarchy with multi-select, batch move and batch delete • Global search: find any file across the entire vault instantly, with full paths • In-app preview: TXT/Markdown editing, PDF and Office preview, audio/video playback, image viewing • One-tap import from your photo library MULTI-KEY & CROSS-PLATFORM • Authorize multiple security keys, each with its own PIN — perfect for backups or family members • Clear key list showing type, authorization time, and source device • Vault files work seamlessly across iPhone, iPad, and Mac FREE & PRO • Free: full encryption, one vault (CodeHouse.vault) • Pro (one-time purchase): unlimited vaults, custom names, multi-key authorization, and everything else PRIVACY PROMISE CodeHouse collects nothing. No analytics, no ads, no tracking. Your files and keys belong to you alone. Note: keep your security keys and PINs safe. With a no-backdoor design, data cannot be recovered if all authorized keys are lost.
