There are 8 kinds of human knowledge.
Most conversations, yours and AI's, stay in the two that are easiest to put into words.
8 shows you all 8, and helps you move the conversation toward the ones you rarely reach.
The empty rows are not missing data. They are potential insights.
These are not categories we invented. They are grounded in how the brain organizes knowledge, distinguishable processes and networks, most of which never surface in conversation.
Your brain offers up What and How first because they are the easiest to put into words. Other kinds of knowledge — systemic Why, context-dependent When, embodied Body, episodic Story — are structurally harder to reach without a prompt. 8 acts as the bridge.
Not a personality type. Not a label. A live picture of which kinds of knowledge you and AI actually use, right now, in a conversation you are already having.
The scan command shows the distribution, names the types that are absent, and offers two paths to bring them into the conversation: a bridging question for the AI to pursue, and one you can ask yourself. 8 makes the gaps visible and proposes where to go next. The conversation follows.
Most AI conversations end and the thinking disappears. 8 turns a live session into a durable, structured record. One command. The session trajectory, the dominant and absent Knowledge Types, the key shifts, the best next entry point, all in a form you can review later, resume from, or carry into the next session. save is the bridge between live insight and continuity over time.
Paste the prompt into your AI assistant (Claude, Gemini, ChatGPT) and start talking. The 8 Knowledge Types light up as you speak.
As you talk, 8 tracks two signals quietly. Friction (ƒ) tells you when the conversation is stalling. Direction (Δ) tells you whether you are moving toward knowledge that is harder to reach or easier.
After a few minutes, type "scan" to see where you have been. Type "trace" to see the shape of the whole conversation. The commands are simple. The patterns are yours.
When you're done, type "save" and the session becomes a durable record. Type "synthesize [artifact]" and the conversation becomes whatever you need: a summary, an email, a plan. Type "focus [type]" any time to move the conversation into a type you want to explore — like Body, Why, or Story.
Surprise — You discover you have been thinking with only 3 of 8 kinds of knowledge. Every conversation. For years.
Curiosity — What would happen if you went to the knowledge types you rarely visit? What is there?
Relief — The stuck feeling has a location. Nothing is wrong with your thinking. You just haven't gone there yet.
Agency — You can see the pattern now. Seeing it is what changes it.
