RESEARCH WITH YOUR BROWSER AND FILES Ask about a web page, summarize a document, or bring a photo into the conversation. Keep your research and follow-up questions together in one chat. MAKE SOMETHING YOU CAN USE Create and edit images with a compatible image service. Build a small website, a useful calculator, or a game, then save it to Home and open it again whenever you need it. TALK IT THROUGH Speak your request and hear replies with supported voice services. Follow a task in chat, pick it up from history, and see the tools Senko uses as it works. YOUR TOOLS, CONNECTED Connect services such as GitHub, Notion, and Home Assistant. A built-in terminal, skills, and custom AI providers give you more control when you need it. Use the managed Senko service or configure a compatible provider. Managed AI features may require a paid subscription and have usage limits. Your own providers may charge separately. Availability depends on your device, permissions, and chosen services. Online AI requires an internet connection. Check important results and actions before relying on them.
