# Project export: Trayc This document was generated by HackStack to give an AI agent context about a hackathon project. Sections are labeled with their provenance; content marked as truncated was cut to keep this document small. ## Project metadata - Hackathon: Cal Hacks 12.0 - Tagline: Capture life, relive it. - Devpost: https://devpost.com/software/trace-75sgha - GitHub: https://github.com/vedevpatel/trayc - Team: 1 GitHub contributor(s) — Ved Patel (6 commits) ## Devpost submission (written by the team) ### Inspiration In our fast-paced lives, we have countless conversations and experiences that fade from memory. We were inspired to create a tool that helps anyone capture and recall the meaningful moments they might otherwise forget, from a busy professional needing to remember key discussion points to a grandparent wanting to cherish family moments. Trayc acts as a seamless, AI-powered extension of your own memory. ### What it does Trayc is an AI-powered memory companion that automatically documents your life's conversations and locations, creating a searchable map of your experiences. Here’s how it works It Listens & Locates: Trayc passively hears your conversations and notes your location throughout the day. It Connects the Dots: The AI seamlessly links every conversation to its specific location on an interactive map. It Talks Back: You can chat or speak directly with Trayc to ask questions about your past. Just ask, "What was I talking about when I was at the park yesterday?" It Replays Your Moments: Simply click on any point in the map to instantly see a summary of what you were discussing the last time you were there. ### How we built it We used Groq for the speed, Vapi for the intelligent voice agents, Python for the backend, Typescript and React for the frontend, and ChromaDB for the vector database. ### Challenges we ran into The location data wasn't being properly captured and passed through the entire pipeline. The problem was processing Vapi transcript events in real-time, so we used event listeners collecting transcript segments during calls, processing on call end with proper speaker diarization. Designing two rag systems: One for reading on screen for text-based input and one for hearing over the phone for audio input. ### Accomplishments we're proud of We were able to store location data corresponding to conversation data in a vector database We achieved sub-second retrieval using Groq. We're proud of building a system with privacy and user control at its core, from the architecture to the UI. We used ChromaDB, which has all safety protocols. Finetuned and engineered the AI to distinguish between a casual chat and an important work discussion ### What we learned We gained technical experience in real-time audio processing and vector databases. We also learned that the most impactful AI applications are those that intuitively augment human capabilities. We also learned that building trust is as important as building features when creating a product that handles sensitive personal data. ### What's next Trayc has an exciting journey ahead of it! This includes features such as the following: With Augmented Reality hardware, Trayc will be able to have a deep understanding of your brain and personality, and identify locations and/or situations where you tend to forget things. Trayc will provide a fun and interactive way to remember everything you need to know at any time.

Trayc will provide a fun and interactive way to remember everything you need to know at any time. The ultimate goal for Trayc is to learn about you and your personality over time, and identify situations and/or locations where you forget things, and intelligently guide you in your life. It will provide real-time information, assistance, help recall memories and conversations, and also provide feedback for users.
