   NodeLand▲533

   Hello, HN! Have you ever considered that you might be a visual thinker?

    I built Asterode to make AI more productive on the go. It focuses on continuity: switching models mid conversation, branching chats, a global memory layer, and keeping useful context without constantly starting over. IT's available on Android and iOS. I’d really appreciate thoughtful feedback.
