Meet Jeff.
He runs my life.

Jeff is a self-hosted AI assistant that manages my email, budget, car, home, calendar, and texts — all running on open-source models on a Mac Mini under my desk. Here's what that looks like.

› "what did I decide about the NAS migration?"
Mar 12, 2026 0.94 relevance
Decided to keep Qdrant on the NAS but move Postgres to the Mac Mini for speed. Migration planned for next weekend.
Mar 8, 2026 0.87 relevance
Benchmarked Qdrant on NAS vs Mac Mini. NAS is fine for recall latency (<200ms). Not worth moving.
