Measure the structural quality of any argument
We often confuse confidence with quality. An argument can feel compelling because of emotional resonance, rhetorical skill, or confirmation bias — even when its logical structure is weak. Without a way to objectively evaluate argument quality, we cannot distinguish between persuasive reasoning and genuinely sound reasoning.
Argument Strength scores your reasoning across six dimensions: Clarity (how precisely the idea is expressed), Precision (specificity vs. vagueness), Assumption Load (how many unverified premises it depends on), Logical Consistency (internal coherence), Nuance (acknowledgment of complexity), and Evidence Basis (grounding in verifiable claims). Each dimension is scored individually, and an overall strength score is calculated.

Provides concrete ways to strengthen your argument
"Renewable energy is always better for the economy than fossil fuels."
42/100 — The claim has clear intent but suffers from overgeneralization, high assumption load, and lack of nuance about economic trade-offs across different contexts.
Nuance (25/100) — The word "always" eliminates all context-dependency, ignoring cases where transition costs, grid reliability, or regional economics complicate the comparison.
Qualify the claim by specifying conditions: "In markets with mature renewable infrastructure and declining fossil fuel reserves, renewable energy increasingly outperforms fossil fuels economically."
Knowing how strong your argument actually is — not just how strong it feels — is the difference between persuasion and intellectual honesty. Argument Strength gives you an objective measure so you can improve before you publish, present, or decide.
