NexaMind AI — Privacy-First Intelligent Workspace

NexaMind AI is an advanced, privacy-first intelligent productivity workspace and multimodal AI assistant built with Flutter and Dart, powered by DeepSeek V3 and R1 reasoning models.

The application integrates an encrypted on-device Drift/SQLite database with streaming conversational AI, deep chain-of-thought reasoning, on-device OCR document scanning, hands-free voice STT/TTS, and an autonomous multi-step AI Agent that orchestrates operations directly into local productivity modules. Built for prosumers, students, and professionals, it provides a 31-tool generative AI Studio alongside integrated offline-first task, note, reminder, study plan, and expense management.

Lead Flutter AI Engineer responsible for mobile client architecture, Riverpod reactive state management, on-device Drift SQLite encryption, DeepSeek LLM streaming integration, and multi-step agent tool execution.

• Flutter mobile client utilizing Riverpod for reactive state management and GoRouter for declarative navigation.
• On-device encrypted database using Drift ORM and SQLite ensuring zero unencrypted user data on disk.
• Streaming LLM client via Dio SSE connecting to DeepSeek V3 and R1 reasoning endpoints with markdown rendering.
• Autonomous multi-step AI Agent architecture executing tool calls directly into local tasks, notes, and calendar modules.
• Google ML Kit integration for on-device OCR document scanning, text recognition, and localized text-to-speech.

• Streaming Multimodal Conversational AI: Real-time token streaming with deep chain-of-thought reasoning from DeepSeek models.
• 31-Tool Generative AI Studio: Specialized utilities for document drafting, code assistance, study guides, and prompt refinement.
• Autonomous Multi-Step AI Agent: Executes tasks, schedules calendar reminders, and organizes notes automatically from conversation.
• On-Device OCR & Document Ingestion: Scan physical documents and PDFs with Google ML Kit for instant summarization and analysis.
• Hands-Free Voice Interaction: High-accuracy speech-to-text (STT) and responsive text-to-speech (TTS) audio narration.
• Offline-First Productivity Suite: Full task, note, reminder, study plan, and expense tracking fully operational without internet.

• Managing token-by-token UI re-rendering at 60 FPS while streaming long responses from DeepSeek reasoning models without memory leaks.
• Ensuring fast database queries across thousands of historical messages and notes using indexed Drift ORM queries.
• Coordinating autonomous agent tool-calling loops without triggering infinite execution states on device.

• Successfully built a comprehensive 31-tool privacy-first mobile AI workspace in Flutter.
• Full on-device encryption ensuring complete user confidentiality for all notes, chats, and productivity data.
• Public video demonstration showcasing multi-step agent operations and deep reasoning workflows.
