Start a 7-day trial

Everything on: planning, memory, the flywheel, the API and the MCP server. No card. Your key is shown once, on this page.

Questions or suggestions? Send a message in the Discord.

By taking a key you agree that the moments your characters' brain was unsure about (features and candidates, never text) train the shared brain every studio starts from. Raw sentences leave your machine only when you send them.

One trial per email. We use the address to identify the licence and to tell you before it ends. Nothing else, no list.

Your key — copy it now, it is not shown again.
Then, in a terminal:
  1. lw init writes a manifest you edit like code.
  2. lw dev --mock runs a town with no engine.
  3. lw trigger theft --char hulda fires a real event and prints the chain.
  4. lw watch and lw why hulda show what everyone is doing, and why.

Trial ends . Then $20 a month, only if you subscribe with lw licence subscribe; nothing is charged unless you do. When the trial ends, your characters lose the ability to plan and to be emergent; reflexes keep running, so nothing breaks, until a studio licence is active. Docs: Characters SDK · the lw CLI.
