Vesper:Chat · Spaulding Labs
Tell us your phone model, your iOS version, and what happened. Please do not send your API key.
Her mind is a language model of several gigabytes, and it downloads once, the first time you open the app. Use wifi, keep the app open and the screen on until it finishes. After that she works without a connection.
Double-tap her (on her, not the sky) and speak. When you stop, she answers. Or type in the box under her. The first time, iOS asks for the microphone and speech recognition; both are handled on your phone.
SYSTEMS › MEMORY. Swipe away a single fact or place, or use “forget everything about me” and hold the button for two seconds. It clears her facts, places, past talks and the conversation for that passenger. There is no undo. Deleting the app removes everything.
SYSTEMS › SHIP › [ RESTORE PURCHASES ]. It brings back what your Apple Account has bought (a character, her clothes, the outside model) after a reinstall or on a new phone. It never charges anything.
An optional one-time unlock (SYSTEMS › LLM) that lets her run on a model on your own computer (LM Studio or Ollama over wifi) or in the cloud with your own API key, instead of the one on the phone. You need your own server or key; the unlock does not include either. While it is on, her messages go to that provider, and only then.
AR needs a room with some light and a surface it can see, such as a floor or table. Move the phone slowly to let it look around. Allow the camera in iOS Settings if you said no the first time.
Vesper:Chat, version 1.0 (build 1). Needs iOS 26.5 or later.
