What Makes Secret AI Your Trusted Private AI Assistant and Offline LLM Chatbot:

[True Privacy & Security – Local AI Processing]
All conversations and image analysis happen directly on your device using local LLM models and offline AI technology. Works without internet connection – perfect for airplane mode, underground areas, or locations without WiFi. Your private data never uploads to external servers, cloud services, or third-party AI providers.

[Custom AI Characters – Personalized Chat Experience]
Create and interact with completely custom AI companions tailored exactly to your preferences. Personalize every detail of your experience: design unique avatars, set custom background images, choose specific names, and even style chat bubbles and input boxes for a truly immersive chat environment. Prompts use the same {{user}} and {{char}} macros as character cards elsewhere.

[Tools, Skills & MCP – AI That Gets Things Done]
Your local AI model can use tools. Connect an MCP server, or write your own Skills as portable SKILL.md files. Every tool call opens up in the chat to show what went in and what came back. Tools stay off until you switch them on, and you approve each one the first time it runs.

[Siri Shortcuts Integration – Voice AI Assistant]
Use Siri to chat with AI without touching your phone! Set up shortcuts to ask questions or analyze images just by talking to Siri.

[Powerful Local LLM Performance – Offline AI Engine]
Optimized AI engines support both CPU and GPU acceleration with popular model formats including GGUF, MNN, and MLX. Choose from various offline AI models based on your device capabilities for optimal local LLM performance.

[High-Quality AI Models – Local LLM Library]
Access leading open-source models like Qwen3.5 VL, Gemma 4, LFM2.5 VL, MiniCPM 5, DeepSeek R1 0528, gpt-oss, Llama 4, Phi 4, Mistral, and other advanced local AI models – download directly from Hugging Face for enhanced offline AI chat experiences.

[API Integration Options – Custom AI Backend]
Connect to your self-hosted LLM API service, Ollama, or local LLM servers within your network for enhanced AI capabilities while maintaining complete privacy.

[Private Image Analysis – Offline Vision AI]
Process and analyze images completely on-device with no external transfers or cloud processing. Your photos remain 100% private and secure with local AI vision capabilities.

[Anonymous Usage – No Registration Required]
Use Secret AI completely anonymously with no account creation, email verification, or personal information required.

**Some premium features (such as GPU acceleration, unlimited chat sessions, MNN models, and advanced image analysis) require a one-time purchase or subscription. Basic offline AI features are available for free.**

AI power belongs in your hands, not in someone’s cloud. Secret AI keeps your secrets secret.
