Overview

Voice Writing Assistant is a personalized AI tool that helps improve your writing while maintaining your authentic voice. Unlike generic AI writing assistants, this tool:

• Learns from YOUR writing samples
• Preserves YOUR vocabulary and style
• Integrates directly into your writing workflow
• Keeps your content private and secure

Architecture

This project consists of two main components:

1. FastAPI Backend: Handles retrieval, generation, and caching
2. Chrome Extension: Provides seamless integration with Notion

Tech Stack

• Vector Search: Leverages RAG (Retrieval Augmented Generation)
• Language Model: Uses Together AI's Mistral 7B
• Performance: Redis caching for sub-second responses
• Integration: Works directly in Notion (more platforms coming soon)
