AI Usage Disclosure
Tonari Days is built by us: the app, Tonari's animation and personality, her reactions and the design are our own work. AI tools help in some places. Her illustrations and the room backgrounds were drafted with image AI, then split into parts, edited and animated by us. The background music was made with a music AI and chosen by us. Her voice is a synthetic voice designed from a written description, not a copy of any real person. Her lines were drafted with AI help and checked one by one by us. While you use the app, a translation model and a voice model run on your own PC. They only translate the text you pick and read it aloud. Nothing is generated on our servers, and there is no free AI chat. Name of AI model included with the game: Hy-MT2 (translation model) and Irodori-TTS (voice model), both running locally on the player's PC. Voices for languages other than Japanese will use Qwen3-TTS, also running locally, added in an update.
