Steelman — Find the Strongest Counterargument

See the most persuasive counterarguments to any article you're reading, powered by your own AI API key.

Reading an article and only getting one side of the story? Steelman shows you the most persuasive counterarguments to what you're reading — the opposing view, argued at its strongest, not its weakest. How it works 1. Click the Steelman icon while reading any article. 2. Steelman reads the page and asks AI for the 3 most persuasive counterarguments to its claims. 3. The counterarguments appear in a side panel, each with its reasoning. Why Steelman is different Most reading tools summarize — they compress what you already believe. Steelman does the opposite: it expands your view by surfacing the strongest opposing case, so you can form a more complete opinion.
