Scatter launches as an AI mind-map study app with bring-your-own API keys

Jakub Fleites-Jonczyk released Scatter, a source-available desktop browser app that builds AI-powered mind maps from a topic, chat or image, with marked terms expanding into connected nodes on an infinite canvas. Users bring their own API keys for OpenRouter, OpenAI, Anthropic or local servers such as Ollama, and projects, sources and keys stay in the browser with no app server in between. The app splits a main model for explanations and chat from a cheaper secondary model for term marking and previews, and sends at most the parent and grandparent nodes as context to limit token costs.
