How it works

Three steps. No code. Your AI key stays yours.

1

Create a persona

Use the web wizard to shape your NPC: personality, speech style, backstory, and the lore of your sim. Roleplay-ready templates included.

2

Drop the object in-world

Place our scripted object in your sim and link it to your persona with one key. Your NPC starts talking to visitors immediately.

3

Bring your own AI key

Connect your own OpenRouter key: you choose the AI model per persona and control your spending directly — prepaid, no surprises. Step-by-step tutorial included.

Prices in EUR, billed via Stripe. Cancel anytime. Annual billing becomes available at launch. You pay your own AI usage directly to your provider (typically a few euros per month for a busy NPC — depends on model and traffic).

Built for roleplay. By a roleplayer.

Generic chatbots break immersion: they forget everything, ignore your setting, and talk like customer support. SimFolk NPCs stay in character, follow your sim's protocols, and speak your world's language — whether your setting is Gorean, Norse, medieval fantasy or anything else. Built by an active RP sim resident, not a tourist.

Lore-true

Feed your NPC your sim's rules and vocabulary. It greets, serves and trades the way your setting demands.

It remembers

Returning visitor? Your NPC recalls past conversations and picks up the thread. (Storyteller tier and up.)

Your model, your rules

Choose any AI model per persona through your own OpenRouter key — including models suited to mature RP settings, subject to the model provider's terms.
