🕸️ Moriarty's Web
🕷️ A Professor Moriarty tool — The spider at the centre of the web
Paste an essay, a proposal, a policy memo, or a fraught email thread, and get a visual map of the argument: the central claim, every premise supporting it, the strength of each connection, and the logical fallacies in the weave — each one named, explained, and quoted. It takes a master of webs to untangle one.

What it does
The argument as a web
Claim at the centre, premises hanging by threads — solid, dashed, or dotted by strength.
Fallacies named and quoted
Ad hominem, false dilemma, hasty generalisation — each pinned to the exact sentence.

How to use it
-
1
Paste the argument — yours or someone else's.
-
2
Untangle: the web draws itself with a soundness score.
-
3
Open the fallacy chips, then export the analysis.
A high soundness score doesn't mean the claim is true — it means the argument for it is well built. The professor insists on the distinction.
