  • MIT-licensed open source, self-hostable with local Postgres and vector DB
  • Adjustable word generation distance from close to home to makes you reach
  • Dig into words by clicking to generate six new words radiating from that one
  • Change your question mid-session and reword it with your kept and sparked words
  • Taste the stew to see your question rewritten with your choices highlighted
  • Ask for ideas that arrive as cards built from your kept and sparked choices
  • Turn ideas over to find analogies from different fields

What makes it different
  • All three tools—Notion, Excalidraw, ChatGPT—unified on one canvas, with the AI reading surrounding context before acting
  • AI outputs placed as editable nodes on the board instead of lost in a chat sidebar
  • Spatial thinking preserved: canvas keeps structure and relationships visible at once, unlike chat
  • Fully open source and self-hostable with no vendor lock-in or proprietary format
  • Recognition is easier than production: react to words instead of articulating ideas from scratch
  • Spark steers the generation hardest and is the most powerful control in the app
  • Your preferences are demonstrated through actions, not just declared
