The whole flow, step by step.
It keeps colliding keys in the same bucket as a short linked list, and once a bucket grows large Java switches it to a balanced tree — so lookups stay fast even when keys collide.

A transcript that keeps up
It follows the speaker closely, so an answer is forming while the question is still being asked.
Excluded from screen capture on macOS, and Windows 10 (version 2004+) & 11. Transparent mode is also available when you want to see through the panel yourself.

What people say
From people who used extraMind in real interviews and meetings.
“What I like most is how quickly I can go from a screenshot to a structured explanation. It saves me the hassle of manually typing out an entire problem when I’m practicing technical questions.”
“ExtraMind is useful for exploring system design questions and comparing possible architectures. I can use AI to organize my thinking, identify trade-offs, and prepare a clearer technical explanation.”
“I like having AI assistance available without constantly switching windows. ExtraMind makes it easier to keep my workflow organized while I work through ideas and prepare for important discussions.”
“The combination of real-time assistance and screenshot analysis makes ExtraMind interesting. I can get help understanding a problem, explore the reasoning, and spend more time learning the concepts behind the answer.”
“I really like the Auto feature in ExtraMind. It makes getting help with straightforward questions so convenient. For scenario-based questions, I prefer to disable Auto and control when the AI responds. That flexibility makes the tool much more useful during interview practice.”
