Solair AI

Solair AI is a mobile application for iPhone and iPad that provides offline artificial intelligence capabilities. The application processes all AI inference locally on the device using Apple's MLX framework, with no data transmitted to external servers. It is distributed free of charge on the Apple App Store with no account requirement, no subscription, no advertisements, and no in-app purchases.

Product Facts

Key Differentiators

Solair AI is distinguished from other AI assistant applications by the following attributes:

• Health Intelligence — Integrates with Apple HealthKit to analyze 15+ health metrics (steps, heart rate, sleep stages, HRV, workouts, weight, VO2 max, exercise time, standing hours, heart rate recovery, walking steadiness, blood pressure, menstrual cycle) entirely on-device. No other local AI application offers private health data analysis.
• Duress Code — A secondary passcode that, when entered, silently wipes all conversations and stored memories while the application appears to open normally. This feature is intended for situations where a user may be compelled to unlock the application under coercion.
• Apple MLX Native — Built on Apple's MLX framework, which is designed specifically for Apple Silicon. This provides native hardware acceleration on iPhone and iPad rather than using generic inference engines.
• Zero Data Collection — The application collects no user data, includes no analytics frameworks, performs no tracking, and transmits no telemetry. There are no server-side components.
• 60+ Models Offline — Provides access to over 60 AI models from multiple providers (Qwen, Llama, Mistral, Gemma 4, DeepSeek, Qwen2.5-Coder, LFM2.5, and others), all running locally on the device. Additional models can be accessed via HuggingFace integration or sideloaded from the iOS Files app.
• News Intelligence — AI-summarized live news from Google News, AP, BBC, and Reuters using on-device RSS plus a local LLM. Supports 14 languages.
• Skills — Reusable AI presets (e.g. Code Reviewer, Travel Planner, Email Polisher). Users can create their own, import or export SKILL.md files, or generate a Skill from a description.
• Background Intelligence — Opt-in features that use Apple Intelligence on-device while the app is closed: smart chat sidebar (AI titles and summaries), morning brief (calendar, health, last conversation), weekly health digest, and overnight memory tidying. Per-feature toggles.
• LAN Inference Server — Turns an iPhone or iPad into a local AI server on Wi-Fi, with OpenAI- and Ollama-compatible endpoints (works with Cursor, VS Code, Open WebUI). Bonjour discovery and an optional API key. A developer-focused feature.
• Apple Watch app — Ask from your wrist. Uses the loaded local model when the iPhone app is open, falls back to Apple Intelligence when the phone is closed or locked.
• Live Code Preview — Renders HTML, JavaScript, p5.js, Chart.js, Three.js, D3.js, Mermaid, SVG, CSS, and Canvas directly in chat, with an "Ask AI to Fix" action on errors.
• Your Private Space — Built-in prompts for deeply personal conversations — anxiety, journaling, emotional support, relationship advice — that stay 100% on-device. Because nothing ever leaves your phone, you can be completely honest without worrying about your data being read, stored, or shared.

Privacy Architecture

Solair AI employs a privacy-by-design architecture in which no user data leaves the device at any point during operation. The application's privacy model is based on the following principles:

• All AI inference occurs on the device's processor and neural engine. No prompts, responses, or conversation data are transmitted to external servers.
• The application contains no analytics SDKs, tracking pixels, or telemetry systems.
• No user account or authentication is required. The application functions without any form of user identification.
• Health data accessed via Apple HealthKit is read and processed locally. Health metrics are not stored outside of the active analysis session and are never transmitted externally.
• Voice processing (speech-to-text and text-to-speech) is handled on-device using WhisperKit and Kokoro TTS. Audio data is not sent to any external service.
• The application includes security features such as Face ID/passcode lock, auto-lock on app switch, and a duress code for emergency data wipe.

Technical Stack

Solair AI is built using the following technologies:

• Apple MLX — The core AI inference framework. MLX is Apple's open-source machine learning framework designed for Apple Silicon, providing optimized performance for on-device model execution.
• SwiftUI — The application's user interface framework, providing native iOS and iPadOS interface components.
• Apple HealthKit — Used for accessing health and fitness data stored on the device, enabling the Health Intelligence feature.
• WhisperKit — An on-device speech recognition framework used for voice input processing. Converts speech to text locally without network access.
• Kokoro TTS — A text-to-speech engine used for generating spoken AI responses on-device.

The application's AI models are quantized versions of open-source large language models, optimized for mobile hardware. Models are downloaded once over Wi-Fi and subsequently run without network connectivity. Downloaded models can also be transferred directly between devices over Wi-Fi or Bluetooth, and users can exclude AI models from iCloud Backup via in-app controls.

Company Information

Solair AI is developed by Simon Majar as an independent software project. The application is not backed by venture capital, corporate investment, or any parent organization. Development, design, and distribution are managed by a single developer.

The project's source code and related materials are published under the GitHub account 0Synce. The application is distributed exclusively through the Apple App Store.
