Using the Chat

What it's for: asking natural-language questions about your DNA data and seeing — and verifying — exactly what the AI receives.

The window

• Top bar: the database path box and … / Open buttons; the backend and model pickers (with ↻ to refresh models); the privacy badge; and the Privacy & Debug toggle.
• Privacy badge: Pseudonymized (green) when identities are tokenized, or REAL NAMES (local only) (orange) when you've enabled real-names mode with a local AI.
• Chat area: your messages, the AI's answers, and grey tool-call lines showing which data tool the AI used (e.g. ⏵ get_matches …).
• Input row: the “ask about your matches…” box and Send (Enter also sends).
• Status line: shows progress — e.g. “done · in 900 / out 1,200 tokens” after each answer.

Reading answers

Names in the AI's reply that DGAI restored from tokens are highlighted. Hover a reply to see a “Restored locally:” list mapping each token to the real name it became — your proof of what actually went to the AI.

The Privacy & Debug panel

Click Privacy & Debug to open a side panel with three tabs:

• What the AI sees — the exact outbound payloads (newest first). Everything here is tokenized; this is all the AI ever receives. Great for reassurance and for the curious.
• Token lookup — type any token (e.g. [M1234]) and click Reveal to translate it to the real value, locally. Unknown tokens report that they were never minted for this database.
• Settings — API key and endpoint, plus the two opt-ins: Send research notes / free text to cloud AI and Real names (localhost AI only). Changes apply the next time you press Open.

What you can ask

Behind the scenes the AI has a set of tools for your data — matches, shared matches, segments, chromosome overlap, ancestor trees, surname/place search, common ancestors, and ancestral hubs. That means you can ask things like:

• Overview: “Summarize this database and list my profiles.”
• Matches: “My top 15 matches over 100 cM, and their side (maternal/paternal).”
• Shared matches: “Who is in common with both [M1234] and [M5678]?”
• Segments & triangulation: “Which matches overlap chromosome 7 between 20 and 40 Mbp?”
• Trees: “Which matches have the surname Hart in Ohio before 1880?”
• Common ancestors: “What common ancestors do I share with my closest match?”
