SecureThink

SecureThink is a premium, offline-first AI studio engineered from the ground up for absolute privacy, hardware-level security, and high-performance intelligence. Process your confidential documents, query encrypted knowledge bases, translate via camera, and orchestrate native agents—with zero server dependencies and zero subscriptions. Important: Minimum 6 GB RAM required (8 GB+ recommended) for smooth on-device AI model inference. Key Features: Dedicated Local Studio Workspaces Tailor your offline AI workflow across 5 specialized, context-isolated profiles: • 🌐 Global Translator: Instant text and in-app camera photo translation. Snap signs, menus, or documents for private, offline translation anywhere in the world. • 📚 Private Knowledge Base (RAG): Query your personal vault. Search confidential PDFs, DOCX, PPTX, and notes using hybrid on-device vector and keyword retrieval. • ⚖️ Contract & Legal Auditor: Review non-disclosure agreements, contracts, and commercial terms locally to identify risks without exposing sensitive business documents. • 🗣️ Language Coach: Practice conversation, grammar, and pronunciation with offline AI feedback and natural voice read-aloud (TTS). • 🤖 General Agent: Coordinate offline system actions including alarms, timers, calendar events, map navigation, and native apps. 100% On-Device & Fast Multi-Turn Performance Experience true privacy with edge AI models running directly on your physical hardware. Advanced warm KV cache reuse cuts follow-up response latency to milliseconds, delivering smooth, conversational interactions without re-processing context. Hardware-Backed Cryptographic Security All local session history, vector indices, and document chunks are protected using SQLCipher AES-256 encryption. Imported files are secured with envelope encryption (AES-GCM-256) backed by the hardware-isolated Android Keystore. End-to-End Local RAG (Retrieval-Augmented Generation) Import PDF, DOCX, PPTX, CSV, TXT, and Markdown files directly into your encrypted local knowledge base. Fast hybrid retrieval and on-device re-ranking ensure accurate, context-aware answers without sending raw text to third-party services. In-App Camera Intelligence & Multimodal Vision Capture photos directly in-app or attach short video clips. On-device chronological keyframe extraction and offline OCR enable edge models to interpret real-world scenes, inspect visual documents, and read results aloud with clear audio playback. Zero-Server & Zero-Knowledge Architecture SecureThink operates with zero server storage. We do not own, operate, or maintain any centralized servers storing your queries or documents. If you delete the app, your data is permanently removed. Privacy Shield & Local PII Redaction for Cloud Mind Optional Hybrid Cloud Gateway allows connecting custom OpenAI-compatible endpoints, local desktop models (Ollama/LM Studio), and Streamable HTTP MCP tools. Built-in Privacy Shield automatically redacts Personally Identifiable Information (PII) before transmission. Local Agent Automation & Offline Tools Run native automation skills including alarms, timers, device state checks, launching apps, sharing summaries, and map navigation—all executing 100% offline with clear user confirmation cards. Purchase once and unlock a complete, secure local AI workspace with no ads, no hidden subscriptions, and no unwanted data tracking.
