"What if you didn’t have to decide whether something is a task, an event, a reminder or something else before you even start? With WhatsNext, everything starts with an Action. An Action can begin with nothing more than a title. Keep it simple or let it evolve as real life does. Share it with one person, several people or a Group. Leave the timing open, add a date when it matters, let someone take it on, or simply keep it visible until the right moment comes. The Action adapts to the situation — not the other way around. One flexible form for what people do together Use Actions privately with people you know, inside your Groups, or as part of a public Group in the Community. An Action can represent something you want to do, offer, remember, share, make happen or invite others to join. The same basic form works across different situations without forcing you into separate categories. Your Groups. One connected system. Friends. Family. Teams. Interests. Communities. Every Group has its own space for Actions, conversations and what is happening inside that Group. At the same time, WhatsNext brings together the Actions that are relevant to you across all your Groups. You don’t have to search through different places to understand what matters. What matters comes to you. Discover what’s around you Explore public Groups in the Community and find people around shared interests, activities and ideas. Join a Group, take part in its Actions, or create your own public Group and bring people together around something that matters to you. WhatsNext can work with the people you already know — and help you connect with people you haven’t met yet. Conversations stay connected Use Group chat, Action chat and direct chat in one place. Talk where things are actually happening, instead of separating the conversation from the context around it. Built around real life Real life doesn’t always begin with a perfectly defined task or event. Sometimes you only know what should happen next. That is enough. Start with an Action. Let it evolve. WhatsNext creates one connected system around the things people do together — private, shared or open to a Community. This is just the beginning. Meet WhatsNext.
