A Argument Lab

Submit a claim and walk through a Socratic analysis. The kernel decomposes your argument, maps its structure, scans for reasoning flaws, and challenges you with targeted questions.

Probe

Enter a claim, statement, or argument below. I'll analyze its logical structure, check for hidden assumptions, and scan for reasoning flaws.

Try something like: "Vaccines cause autism because my neighbor's child developed symptoms right after being vaccinated."

⚠️ Limited mode — you're using free open-source models as a fallback. Results may be slower, less reliable, and significantly less accurate than frontier models. For the best experience, create an account and add your own API key. How to get an API key

Argument Map

Argument Map

A visual diagram showing an argument's logical structure — claims, premises, and how they connect.

An argument map displays the logical skeleton of a text: Claims (main conclusions), Premises (supporting statements), Counters (opposing points), and Rhetorical elements (persuasion techniques). Edges show how parts relate: Supports (reinforces), Rebuts (contradicts), Qualifies (limits scope), or Annotates (adds context). This visualization helps identify weak points, hidden assumptions, and the overall strength of an argument at a glance.

Detected Aspects

Aspect

A specific reasoning error, cognitive bias, manipulation technique, or argumentation pattern in our taxonomy.

Each of TellDear's 452 aspects represents a distinct reasoning pattern — from formal logical fallacies (ad hominem, begging the question) to cognitive biases (anchoring, confirmation bias) to propaganda techniques (loaded language, false dilemma). Every aspect has a definition, real-world examples, verification steps for AI detection, a formal logic pattern, and links to related aspects.
