Use it to plan a project, compare options, explore a research question, or structure what you are learning. SEE HOW IT WORKS Explore a prepared example before signing in. Tap through the factors behind a release decision, challenge an assumption, and see a practical next step. The example works without a cloud request. MAP YOUR QUESTION Start with a rough sentence.

TEST YOUR THINKING Look for weak assumptions, missing information, and cases that could change your conclusion. Import source material and keep track of what has actually been tested. AI suggestions are not verified evidence. ASK ABOUT YOUR STUDY Chat with AI using the context of your map. Review proposed additions before adding them to the graph.
