SecondBrain is an intelligent virtual assistant powered by Python, LangChain, and OpenAI. Its purpose is to serve as a functional second brain to help manage a variety of workloads, increase productivity, and reduce cognitive overload. Right now, we are at in an experimental phase where we are conducting theory of mind experiments by getting SecondBrain to talk to itself - a necessary precursor to developing a true understanding of what someone else really wants is being able to create a simple mental model of them in your own head, called a Theory of Mind in psychology.
The concept of a "Second Brain" is a methodology for saving and systematically reminding us of the ideas, inspirations, insights, and connections we've gained through our experiences. By creating an external, digital repository of the things we learn, we can significantly reduce cognitive load, streamline our workflows, improve decision-making, enhance creativity and innovation, and boost mental health.
SecondBrain, the app, aims to take this concept to the next level by leveraging the power of language models and the LangChain framework. It serves as a personal assistant that not only stores and organizes information but also understands it, connects it, and uses it to assist the user in making decisions and solving problems.
LangChain
LangChain is a framework for developing applications powered by language models. It supports a range of modules, including models, prompts, memory, indexes, chains, and agents, enabling language models to interact with data and environments in complex ways. LangChain can be used to create applications that can remember interactions, answer questions, interact with APIs, extract structured information from text, and much more.
Language Models
Language models are AI models that can understand, generate, and do tasks with human language. They are trained on a wide variety of internet text, learning grammar, facts about the world, reasoning abilities, and also some of the biases in the data they were trained on. OpenAI's language models, such as GPT-3 and Codex, are leading examples of this technology.
Second Brains
A Second Brain is an external, digital repository where you store the ideas, inspirations, insights, and connections you've gained through your experiences. It serves as an extension of your own brain, reducing cognitive load and increasing efficiency. It is a methodology for offloading the task of remembering and connecting information to a digital tool, freeing your mind to focus on creativity and critical thinking.
The SecondBrain project is organized into several directories, each with a specific purpose:
-
./manager/: This directory contains the Python code for the manager. The manager is a LangChain agent that receives initial requests from the user and dispatches the researcher agents to assemble a response and host the conversation. -
./researcher/: This directory contains the Python code and Dockerfile for the researcher. The researcher is a LangChain agent that can be passed a number of Tools to perform searches, lookups or API requests needed to gather information for researched responses back to the manager and user. -
./tracing/: This directory sets up the LangChain tracing server for debugging agent execution chains. -
./workflows/: This directory controls the GitHub Actions workflows that build the images, deploy them to the container registry, and set them up for deployment.
These components work together to provide the functionality of the SecondBrain application.
