DGAI Help

DGAI lets you chat with your GDAT data — privately. Ask an AI plain-language questions about your DNA matches, shared matches (ICW), chromosome segments, and your matches' family trees — and get answers that use your relatives' real names, without those names ever leaving your computer when a cloud AI is used.

What makes DGAI different

Ordinary AI chatbots would see every name in your database. DGAI doesn't send them. Before anything goes to a cloud AI, every person, surname, place, and group is replaced with a stable token (like [M1234] for a match or [S7] for a surname). The AI reasons over tokens; DGAI translates the answer back to real names locally, on your screen. See How Your Privacy Works for the full picture.

What you can ask

DGAI can answer questions like:

• “Who are my top 10 matches, and which ancestral line do they cluster on?”
• “Which of my matches share DNA with both Mary and her brother?”
• “Find matches whose trees contain the surname Hart in Ohio before 1880.”
• “What common ancestors do I share with my match on chromosome 7?”

See Using the Chat for more examples and how it works under the hood.
