Plan «ДА» is a wedding-planning service and full-service agency based in Moscow and the Moscow region. Its free online planner helps couples bring the key parts of a wedding together in one place, without registration to begin. After answering seven questions about their city, date, guest count, budget, and preferences, users receive three wedding concepts, each with a suggested venue, team, and preliminary estimate.

The planner includes a budget that recalculates when users change services or prices, payment planning, guest lists, seating arrangements, schedules, and task checklists. An integrated AI assistant answers questions using information from supplier listings and explains how choices affect the estimate. Prices are identified as estimates or supplier-confirmed amounts, and users can browse venue and vendor categories independently.

For couples who prefer hands-on support, Plan «ДА» also offers wedding organization, including venue and supplier selection, preparation, and day-of coordination. The agency provides a free initial meeting. Wedding professionals can also list profiles, work samples, and prices to receive inquiries.
