What students learn

Classroom use cases

Warm-up: Fallacy Quiz

Fallacy Trainer →

10 minutes at the start of class. Students quiz themselves on fallacy recognition, then compare answers. The Trainer generates a new question each time — no two sessions are the same.

Group exercise: Analyze a text

Text Analyzer →

Project a news article, political speech, or advertisement. Run it through the Analyzer together. Students discuss which aspects were flagged and why — moving from intuition to structured critique.

Assignment: Steelman the opposition

Steelman →

Students take a position they disagree with and must use the Steelman app to construct the strongest possible version of it. Builds empathy, rigor, and argumentation skills simultaneously.

Reference: Aspect presentations

Aspect Directory →

Assign one aspect per student. Each researches it in the directory, finds a real-world example, and presents it to the class. Works as a semester-long project or a single lesson.

Why TellDear for education

Getting started

No account needed for browsing the Aspect Directory or using the Fallacy Trainer.

AI-powered apps (Text Analyzer, Steelman, etc.) work in free mode out of the box. For better results, students can add their own API key from any supported provider. A shared class key works fine too.
