AI-NATIVE WORLD BUILDING

The AI librarian
for your campaign world.

Describe your world in plain language. Nocera extracts every NPC, location, faction and item into a wiki that links itself — so the only thing you write twice is your villain's monologue.

Kaelen Vex, a half-elf rogue exiled from Silverbrook, runs a smuggling ring out of the Ember Docks. He answers to the Ashen Court, but secretly he's negotiating with the Velvet Compact to switch sides.
Kaelen sounds like a character with real tension built in — the kind of NPC who could become a crucial ally or a backstabbing problem.
  • On his position — is Kaelen actively trying to defect, or playing both sides?
  • On Silverbrook — what got him exiled?

01 / WHAT IT DOES

A wiki that
writes itself while you talk.

Four primitives, designed to disappear. You stay in flow with your story; the structure happens in the background.
01 AUTO-EXTRACTION

Tell it a story. Get a wiki.

Every name, place and faction you mention becomes a typed entity, with relations resolved and properties filled in.

02 STAY IN CONTROL

Lock what's canon.
Hide what's secret.

The AI never overwrites locked facts. Private notes stay yours.

03 FAST LOOKUP

Type a name.

02 / PREP IN MINUTES, NOT HOURS

A whole session, prepped
before the pizza arrives.

Most prep is searching for what you already wrote. Nocera drops that to seconds, so you spend the time on the part you love — making it up.

Works with D&D 5e, Pathfinder 2e, Blades in the Dark, Call of Cthulhu, Daggerheart, and any homebrew system.
