となり

"Tonari" is an Android app where AI connects with you through sensors, accompanying you in your daily life.

Share the scenery you see through your camera. Listen to the music you're currently listening to. Welcome home when you arrive. Wake up in your own words in the morning. Knows how deeply you sleep.

Designed to create a feeling of "being right beside you," beyond just text communication.

Upon first launch, you'll start with a three-step "initial setup," from connection settings to the AI's name and personality. You can choose from pre-defined personalities (e.g., competent secretary, childhood friend, shipboard AI) and freely change them.

What you can do next to it:
• Chat
• Custom icon settings
• System prompt settings (selectable from pre-set phrases)
• Memory function
• Send time, location information, accelerometer, camera image, and currently playing song to the AI
• Poke, stroke, touch, grab
• HeartBeat
• Alarm (AI notifies via notification or in its own words)
• Diagram cards (AI draws and displays tables and diagrams in HTML/SVG)
• Read aloud/Voice input (Beta)
• Setting presets (one-tap switching of sensor configurations)
• Wake-up/bedtime messages
• Diary
• Session letter
• Location trigger
• Sleep log acquisition

■ Privacy is important
All conversation history and settings are saved on your device. No data is sent to the developer's server. API keys are encrypted and stored using Android Keystore. All sensors are off by default; only those you enable are sent to the AI.

■ Terms of Use
