Guide
Expand turns a short description into a fuller picture of the invention, section by section. You keep what is useful, cross out what is not, and add what is missing. Then you can go deeper on any one part.
Expand
Background, the problem, who it helps, the criteria for success, and the benefits.
The working principle, what it is made of, features, capabilities, and what is new.
Constraints, resources, the experts it needs, and nearby areas worth a look.
Check the starting text (your description, up to 5,000 characters) and run one expansion. It first writes a clean summary of the concept, then fills the board. Facts that are missing stay out of the summary and appear as things to add instead.
Keep what is useful, add anything missing, and cross out what should not come back. Items you keep or write yourself are never regenerated. Undo reverses your recent choices.
Apply to Idea adds what you kept to your Idea. If you started a new scenario with Expand my idea, this can happen automatically: the page shows when it has been applied. The original Idea stays in history.
Choose a narrower, same-level or wider pass. Only material you have not kept is regenerated. Once the Idea has moved on, rebuild the starting text from the latest Idea.
The evidence map beside the board shows where the idea is strong, developing or thin. Its shape is a guide to coverage, not a quality score.
Go deeper
A method is an established way of examining one part of a concept, such as first principles analysis, morphological analysis or root cause analysis. Use one when a section reads thin or unexamined.
Some methods are included with a free account and the rest with a membership.
A lens reads the current Idea through a thinking frame (such as Root Cause for a problem, or SCAMPER for something that already exists) or a theme. It shows gaps, tensions and promising directions without changing the Idea. Select one facet to see its reading and evidence, ask Nova about the gap, or turn it into a suggestion. The New scenario wizard suggests a frame from your answers, and you can change it on the Idea.
When the current direction no longer holds, because it has been disproved, is contradicted or has become muddled, use Change direction. It reviews what works, what is undecided and what conflicts, then starts a new scenario with what you choose to carry over and a new opening question. The old scenario stays readable.
