It then identifies the clusters of cocnepts that are furthest apart from each other — they appear in the same context (your texts) but are not well connected.\n\n### 3. InfraNodus will then use the AI to generate a question / prompt that bridges this gap — touching upon relevant topics but connecting them in a new way.\n\n![structural gap infranodus](https://infranodus.com/images/front/infranodus-structural-gaps-ideas.jpg)"
