by Isham Faizal

Shows a generated reply token by token and highlights which earlier tokens influenced the one you tap. It is a simplified picture of how language models decide what to look at.

Maker notes the visualization is highly simplified; works from fixed example prompts rather than your own text.

Source checked 2026-10-16. Descriptions summarize the maker's own account, not independent testing.
