THE SESSION JOURNAL

The chronicle writes itself.

While other tools make you take notes after every session, Omnis records the history as you play. Every change to your world during a live session is captured automatically — no separate notes required, ever.

Auto-logging

Start a session. Every entity edit — NPC locations, item ownership, faction control, status changes — is automatically captured as a WorldEvent. You never write what happened.

Plain English

Events are recorded as readable sentences, not database entries. 'Kaelen moved to The Sunken Citadel' — not 'locationId changed.' Your chronicle reads like a story.

Every entity remembers

Every NPC, location, item, and faction carries its complete history across every session. See exactly when anything changed, who was involved, and what session it happened in.
