NPCAgent [v0.9.2] By DigitalDreamer

You are not the main character here. Join as PersonX and you are a fourth person in someone else’s town. They talk about you once you leave the room, they make plans that do not involve you, and they carry on whether you show up or not. The NPCs need a language model to think, so pick an engine in the top bar. Three call an API. The fourth downloads a model once, runs it inside your browser, and after that you can pull your network cable and keep playing. Run logs upload as bug reports unless unticked.

If you’ve ever got SillyTavern up and pointed at your own backend, that dropdown will feel familiar. Difference is nobody here is roleplaying with you. They’re busy living. Worth saying straight: how good this gets depends on the model you point it at, more than on anything I wrote. A small local one holds the JSON together and not much else. Something stronger and they start scheming at each other. If a model refuses to answer, switch engine.
