Inspiration
In our fast-paced digital world, we're constantly accumulating knowledge from various sources. We realized there was a need for a tool that could not only store this information but make it truly useful and accessible. Inspired by the concept of a "second brain," we created MindBlock to help people organize, retrieve, and interact with their personal knowledge base effortlessly.
What it does
MindBlock is an AI-powered personal knowledge management system. It allows users to upload various types of content - from notes and documents to web pages. Our app then processes this information, creating embeddings using OpenAI and storing them in Convex's vector database. Users can then interact with their knowledge base through a chat interface, asking questions and retrieving relevant information using LangChain's RetrievalQAChain.
How we built it
We built MindBlock using a modern tech stack centered around Convex:
Frontend: React.js for a responsive and intuitive user interface Backend: Convex for serverless functions, real-time data sync, and vector storage Authentication: Convex Auth integrated with Clerk for secure user management AI Integration: OpenAI for generating embeddings and powering our chat interface Retrieval System: LangChain's RetrievalQAChain for intelligent information retrieval File Storage: Convex's built-in file storage system for handling document uploads
Challenges we ran into
One of our main challenges was optimizing the vector search to provide accurate and fast results, especially as the user's knowledge base grows. We also had to carefully design our data structure to efficiently store and retrieve information while maintaining user privacy. Integrating multiple services (Convex, OpenAI, LangChain) seamlessly was another hurdle we overcame through careful planning and testing.
Accomplishments that we're proud of
We're particularly proud of creating a user-friendly interface that simplifies complex AI and database operations. Our implementation of Convex's vector store for efficient similarity search is another highlight. We also did it in a very short span of time.
What we learned
This project deepened our understanding of vector databases and their applications in AI-powered search. We gained valuable experience working with Convex's backend services, particularly in leveraging its vector store capabilities. The process of integrating multiple AI services taught us a lot about building scalable, intelligent applications.
What's next for Mind Block
We have exciting plans for MindBlock's future:
Integration with popular services like Notion and social media accounts for seamless data import Implementing more advanced NLP features for better content understanding and linking Developing a mobile app for on-the-go access to your second brain Enhancing the AI's capability to generate insights and connections within the user's knowledge base Exploring collaborative features for team knowledge management while maintaining privacy
These improvements will make MindBlock an even more powerful tool for personal and professional knowledge management.
