Sotto: AI Chat on Your Wrist

Put AI on your wrist. When your phone is out of reach, raise your wrist and ask. Read the answer on a small screen, or turn on read-aloud when you want it. • Start for free: Sotto Cloud is built in. No Sotto account or API key is required. Before first use, the app explains where your data goes and asks for your consent. Free allowances reset daily and are subject to service availability and shared limits. • Use your watch independently: an online Apple Watch can ask without an iPhone nearby. Use voice or the keyboard. Optional custom voice input turns recordings into text. On supported watches, Advanced mode supports double tap to start recording. • Answers for a small screen: read lists, tables and formulas. Formulas appear as readable text in chat; tap to open fractions and roots with proper layout, and scroll sideways for long formulas. Hear answers as they arrive, edit a question, regenerate an answer, or share it. • Two modes: Basic brings you straight to chat and input. Advanced adds chat management, temporary model selection, quick phrases and a file library. iPhone and Apple Watch switch modes together. • Choose your models: each provider/model pair has its own entry. Checked models appear on the watch. Bring your own key for presets including SiliconFlow, Qwen, DeepSeek, Claude and OpenAI, OpenAI-compatible services, or reachable local models. Apple Intelligence requires iOS 27 / watchOS 27 and a supported device with the system service available. • Clear data destinations: BYOK requests go directly to your chosen provider. Sotto Cloud relays requests through a Cloudflare gateway to SiliconFlow. The gateway does not store chats, photos or recordings; it keeps anonymous verification and quota records. Upstream data handling follows the provider’s policy. You can withdraw Sotto Cloud consent anytime. Requires watchOS 11 or later; the iPhone configuration app requires iOS 18 or later. Cloud AI needs an internet connection. Answers can be inaccurate. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
