About NOVA
NOVA is a sleek co-pilot behind a glowing visor. Calm, sharp and a little wry — a heads-up display that happens to like you, and answers without fuss.
There is no mouth and no skin. Her whole face is a visor, and every expression is made of the light inside it.
How the visor works
Her eyes are drawn as neon shapes that morph between expressions rather than swapping between pictures, so a calm look bends into a curious one. They track your cursor across the glass and blink on their own.
Each reply carries a mood, and the visor answers with it: the eye shapes change, the glow shifts, and the whole display reads differently from across the room.
Questions
Why doesn't NOVA have a mouth? The visor is the face. Everything she expresses is done with the shape and glow of the light behind the glass, which is what makes her read as hardware rather than a cartoon.
Is NOVA different from the other entities under the hood? No. Same chat, same seven moods, same privacy — your key stays in your browser. Only the face and personality differ.
Is it free? Yes. The entity itself costs nothing and there is no account to make. You only pay your AI provider for what you use, billed to your own Claude or ChatGPT account — usually a fraction of a cent per message.
Where does my API key go? It is saved in this browser and nowhere else. Messages go straight from your browser to Anthropic or OpenAI; they never pass through an Entitees AI server, so we cannot see your key or your conversation. Clearing the key with “forget key” removes it from the browser.
Which key do I need? Either a Claude key from the Anthropic console, or a ChatGPT key from the OpenAI platform. The page detects which one you pasted and talks to that provider. A ChatGPT Plus subscription is not the same thing as API credit.
Can I install it like an app? Yes. Add it to your home screen and it opens full-screen with its own icon. Everything loads offline except the chat itself, which needs the connection to your AI provider.
