Donor-facing AI assistant

A chat assistant in the donor portal that answers donor questions about their giving — "how much have I given this year?" "when's my next recurring charge?" "can you cancel my January donation?" Phase 1 is read-only Q&A, Phase 2 enables actions (cancel, update, refund), Phase 3 becomes proactive ("your tax statement is ready"). Cuts donor support volume dramatically while improving the donor experience.
