besir is an iOS planning agent that connects the apps on your phone. Today a plan is spread across apps: an event a friend posted, a restaurant on a map, a booking in a reservation app, the time in your calendar, and you copy and paste between them yourself. besir sits in the middle. Share screenshots, snap a photo of a storefront, or just say what you want. Muse Spark Open reads the images, and Muse Spark turns everything into one plan for the day: events with real places, every travel leg checked with Google Routes, a departure alert for each leg, and a meal fitted into a free gap. When plans change, ask to move or swap something and see the before and after. Each piece is handed to the app that needs it (Apple Calendar, and simulated delivery, reservation and budget apps), filled in so you only check it and tap Confirm. Any partner that sends its own field list gets the same card, with no new app code. Tell besir a preference once, such as "I always take public transit", and it keeps it as a rule you can see and delete. Nothing is added to your calendar or sent to a partner until you confirm.
