How It Works

Document Processing

When uploading a file, the system:

1. Splits your document into segments (small sections)
2. Encodes each segment into numerical vectors for similarity search
3. Extracts entities and relationships to build a knowledge graph
4. Stores the data so it can be retrieved when you ask questions

Retrieving Discussions

When sending a question:

1. Your query is converted into a numerical vector
2. The most relevant segments are found using similarity search
3. Linked entities and their connections are retrieved from the knowledge graph
4. All context is sent to the AI to generate a response
