What it does
Persuasive writing mixes three kinds of sentence so smoothly that you cannot feel the joins. A number, then a "so", then a "clearly", and by the end you believe the opinion because the number was true. The text might be right. You just cannot tell where the weight is. This prompt sorts every sentence that carries weight, with a quote beside each label, by how it is written rather than by whether the AI agrees. It flags lines that use fact words ("studies show", "experts agree") without a source or a number. It traces the chain from the facts to the main claim and shows where that chain leans on an opinion or an unsourced fact. You get the three to six facts to check first, with how to check them, and a count of each kind.
You give it
- The text in full
- The main claim, if you can tell (advised)
- What you need to decide (optional)
You get
- Every weight-bearing sentence labelled with a quote
- Opinion dressed as fact, flagged
- The chain the main claim rests on and the facts to check first
- A count of facts, inferences, opinions and predictions
