Ask HN: Building a Personal AI Avatar. What Technical Are Essential?

4 points by peefy 13 hours ago

Technical: How to reliably structure/unify unstructured cross-channel data (chat texts, call transcripts, email threads) into a consistent "single source of truth"—without losing context like timelines or speaker intent? Scenario: Can it avoid dropping critical details (e.g., a client’s verbal budget limit from a call vs. written feature requests in email)?

Technical: What’s a pragmatic way to balance personalization (needing access to private data) with security (preventing leaks of family chats, work contracts)? Scenario: Is end-to-end encryption + local data processing feasible for a non-enterprise user, or will it kill usability?

Technical: How to make the avatar’s "memory" actionable (not just a archive)—e.g., linking past interactions to current tasks? Scenario: Can it auto-pull a 6-month-old chat about a friend’s allergy when I’m planning a dinner, instead of me manually searching?
