Psychic | 🦜️🔗 LangChain

This notebook covers how to load documents from Psychic. See here for more details.

1. Follow the Quick Start section in this document
2. Log into the Psychic dashboard and get your secret key
3. Install the frontend react library into your web app and have a user authenticate a connection. The connection will be created using the connection id that you specify.

Use the PsychicLoader class to load in documents from a connection. Each connection has a connector id (corresponding to the SaaS app that was connected) and a connection id (which you passed in to the frontend library).

!poetry run pip -q install psychicapi langchain-chroma

[notice] A new release of pip is available: 23.0.1 -> 23.1.2
[notice] To update, run: pip install --upgrade pip

from langchain_community.document_loaders import PsychicLoader
from psychicapi import ConnectorId



google_drive_loader = PsychicLoader(
    api_key="7ddb61c1-8b6a-4d31-a58e-30d1c9ea480e",
    connector_id=ConnectorId.gdrive.value,
    connection_id="google-test",
)

documents = google_drive_loader.load()

We can now convert these documents into embeddings and store them in a vector database like Chroma

from langchain.chains import RetrievalQAWithSourcesChain
from langchain_chroma import Chroma
from langchain_openai import OpenAI, OpenAIEmbeddings
from langchain_text_splitters import CharacterTextSplitter

text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
texts = text_splitter.split_documents(documents)

embeddings = OpenAIEmbeddings()
docsearch = Chroma.from_documents(texts, embeddings)
chain = RetrievalQAWithSourcesChain.from_chain_type(
    OpenAI(temperature=0), chain_type="stuff", retriever=docsearch.as_retriever()
)
chain({"question": "what is psychic?"}, return_only_outputs=True)
