Memoiz - Mood Tracker Demo

31 March - 7 April 2023
Lablab.ai: Build your AI Startup Hackathon. Episode 2

Ever thought of "I wish I could Google my own brain?" The future is now! Memoiz is a semantic search tool for your database that allows you to search for your data using natural language. Paired with a powerful language model, Memoiz can chat with you and help you find what you are looking for.

This current demo is an example of how Memoiz can be used. It is a mood tracker database where you can log your mood and Memoiz will help you remind you of your past days.

Team: We Have Absolutely No Idea

Why & How we are building Memoiz

Extracting information from a large database can be difficult, especially when you don't know what to look for. That's exactly why ChatGPT and friends were born to assist Google. However, these models are not to be used for personal data. Sometimes, you just want to know what you did last week, or last year. Sometimes, you just want to know what kind of person you were. And, sometimes you want a deep analysis on your thought and past.

Here is how Memoiz works. First, you have your primary database. This is where you store all your text data. Then, you might have a secondary database. This is where you store the embeddings of your text data. (It is possible that both can be on Redis Stack) When the text data is "archived", its content will be embedded by Cohere Embed, turning into a (seemingly but not) meaningless 4096-dimension vector saved into the Redis server. When the user starts chatting with Memoiz, the chat history will determine the keywords for semantic search on the Redis server. The closest vectors will be treated as a context for the text generation prompt. The text generation prompt will then be sent to the Cohere Generate model for the chat response.

In the next steps, we plan to develop a larger-scale mood tracker with a more powerful language model. We also plan to share a public API for developers to use Memoiz in their own projects.

Database Setup

For members

We use MySQL on PlanetScale as a primary database. Please connect to the PlanetScale via the CLI

Login to your PlanetScale account

pscale auth login
pscale org switch wahni
pscale connect hackathon dev

or

yarn pscale

Put mysql://localhost:3306/hackathon in the .env file

Then,

npx prisma db pull

to pull the database schema from PlanetScale.

Optionally, you can use the npx prisma studio to view the database schema.

For non-members

Please set up your MySQL database and put the connection string in the .env file

Redis Server

To serve locally, run

docker run -p 6379:6379 -it redis/redis-stack-server:latest

And put REDIS_URL=redis://localhost:6379 in the .env file

Authentication Setup

Please put in Discord OAuth2 credentials in the .env file And set up NEXTAUTH_SECRET according to the .env.example file.

docker run -p 6379:6379 -it redis/redis-stack-server:latest
