It involves two steps: document ingestion and similarity search.

During ingestion, relevant documents are provided to the model as training data. In similarity search, the model compares the user's query with the learned representation of the documents to retrieve relevant information.

This enables the model to generate more informed responses by incorporating external knowledge.

It costs nothing. All document processing is performed locally using an open-source embedding model.

Chat with confidence!

No. We DO NOT store or analyze the content you type. We do not upload your documents to our server. Your OpenAI API key is securely stored in the Apple Keychain, which adheres to industry standard encryption methods.

You can also customize the API endpoint to your proxy server.
