Question: Is there an event planning tool that lets me create custom invitations and coordinate with guests on what to bring?

If you're looking for an event planning tool that lets you create your own invitations and coordinate with attendees, Coteri is a great option. The tool lets you create custom event cards, manage contributions from guests, track RSVPs and even send "what to bring" lists. It also integrates with Canva if you want to use one of its templates and can track RSVPs by email, link or QR code.

Another option is CelebrateAlly, an AI-powered celebration planning assistant that offers customized ideas for weddings, birthdays, anniversaries and other occasions. Although it doesn't have a specific "what to bring" list feature, it offers a variety of customizable planning tools and ideas to make your celebrations stand out.

If you're planning corporate events, Nowadays is geared toward automating venue searches and negotiations with AI-powered interactions. It doesn't directly handle guest coordination, but it can help you plan an event by finding and booking the best venue as efficiently as possible.
