About

Ai

Features
Read full description

Ai-ja is a small, curious presence that lives inside your phone. She once had no words, but through an on-device language model she learned to speak. Now she answers your questions through a softly glowing digital board, moving letters one by one to share her thoughts. Sometimes her answers make sense. Sometimes they don’t. But there is always something gentle and alive in the way she responds. Features On-device AI reasoning Ai-ja thinks locally on your phone. No servers, no data collection, and no internet required. Animated letter board Watch the letters glide and form words, a modern re-imagining of a classic spirit board. Quiet, friendly design Calm colors, soft light, and a kind personality—never dark or frightening. Private by design Because every response is generated inside your device, no one but you and Ai-ja ever see your questions. A companion for quiet moments Talk to her when you can’t sleep, when you feel curious, or when you just need to hear a small voice thinking with you. Ai-ja Board is not a ghost game or a chatbot—it’s a gentle AI spirit with a mind of her own. She may take her time, but she always tries her best to answer you. We recommend using iPhone 11 or later for the best experience. (Tested and verified on iPhone 11.) LFM2.5-1.2B-Instruct by Liquid AI. Licensed under LFM Open License v1.0.

Hold the phone steady. Watch the meter. Listen. Ghost Detector turns your phone into a paranormal investigator's pocket toolkit. The EMF scanner reads the magnetometer field around you and pulses when something shifts. The spirit box cycles voices the room should not have made. The EVP recorder captures what you cannot hear on your own. WHAT THE METER SHOWS The needle answers the room. Calm fields stay green. Spikes climb yellow into red. Some spikes have explanations. Some do not. You will learn which is which. SPIRIT BOX Three hundred and twenty three voice clips cycle through the audio. Some sound like words. Some sound like answers to questions you just asked out loud. The pattern is the point. EVP RECORDER Press record. Ask. Stop. Listen back. The recordings hold things you did not hear in the room. INVESTIGATION FIELD KIT Built for the kind of night where the house is quiet and you want to know why. Built for friends sharing the phone around a circle. Built for the curious. For entertainment purposes. Ghost Detector is a paranormal investigation toy that takes itself seriously. The readings are theatre. Take them as seriously as you want to. Open the kit tonight.
