Each token of the model's answer is colored by how uncertain it was when it
chose that word. Calm green = near-certain. Hot red = a genuine fork. Hover any token to see the
ten alternatives it weighed. Runs entirely in your browser against any OpenAI-compatible endpoint.

⚠Temperature ≠ 1 distorts the signal. Logprobs are temperature-scaled — at 0 they
collapse to a point mass (everything green); above 1 the spread is artificially inflated.
