Secure Notes AI vs Enigmus

Advanced encryption protects every note you write, right on your device. Your private data stays hidden from everyone but you. The built-in AI runs entirely on your device. Ask questions, get summaries, pull insights from your notes -- all without anything leaving your phone. Precision search jumps you straight to the exact word or phrase you're looking for. Full offline support means your notes are always available, connection or not. And star your most important notes to keep them right at the top. No ads. No tracking. No cloud AI. Just your notes, your device, your privacy.

Enigmus runs large language models entirely on your device. Conversations never leave your iPhone, iPad, or Mac - no accounts, no servers, no network required after the initial model download. Hardware requirements: iPhone 13 or newer (A15 Bionic or later), an iPad with an M1 chip or newer, or any Mac with Apple silicon. Features - Ships with a small bundled model, so you can start chatting on first launch without downloading anything. - Download additional open-weight models from Hugging Face, including Qwen3.5/3.6 and Google's Gemma 4 families. The picker recommends models that fit your device's available memory. - Streaming responses with markdown and code-block rendering. - Reasoning-capable models show their thinking before the final answer. - Local chat history backed by SwiftData — conversations stay on the device. - Adaptive layout for iPhone, iPad, and Mac, with keyboard and pointer support on the larger screens. - Customize tint color, fonts, and haptics in Settings. Privacy All inference runs through MLX, Apple's on-device machine-learning framework. No telemetry, no analytics, no account. The only outbound traffic is the optional model download from Hugging Face's public CDN.
