WaifuAI is an AI waifu chat you open in any browser. Pick an anime character, say hi, and she answers in her own personality. The hosted version comes with a free AI model and free voices, so there is no subscription to pay for and no account to create.
Most AI waifu chatbots are a profile picture next to text. In WaifuAI your companion is an animated Live2D character who blinks, moves and reacts while you talk. Choose from more than 50 Live2D models, or add your own.
Your AI waifu reads her replies out loud, with several voices and languages to choose from, including Kokoro voices that run on your own device. Hold the microphone button to talk back instead of typing.
Write her persona: who she is, how she talks and what she likes. She keeps memory of your conversations, so she remembers you between sessions. All of it is stored in your browser, not on a server.
Ask her to draw something, or for a selfie, and she sends you a picture. The background follows the story too: move the chat to a beach at sunset and the scene changes with you.
She understands and answers in many languages, including Russian, Japanese, Spanish, German and Chinese. Pick your language in the settings and she replies in it.
