Paste one cell's gene counts, get a cell-type call with the marker evidence behind it, plus the C2S sentence and reversible rank-to-expression transform. Runs entirely in your browser.
Rank-based marker enrichment against canonical panels, in the browser. Each panel marker found in the cell adds 1/log₂(rank+1), so top-ranked markers count most; scores are normalized by panel size and softmaxed. This is annotation, not the C2S LLM, but it answers the same question with visible evidence.
