iKnow open-sources a read-only viewer into macOS's hidden personal knowledge graph

JeremyCMorgan · x · 2026-11-12

iKnow (556 stars, Apache-2.0) opens macOS's local knowledge graph — who you know, inferred relationships with confidence and provenance, photo faces, location predictions — which Apple barely documents. A single-process, no-dependency web app shows what's recorded, inferred, and which system components read it, plus a manual for letting agents query it.
