An illustrative use case

A question to bring back to the text.

A text dismisses opponents as people who do not care, without addressing their objections. Ask learners to separate a claim about motives from a response to the argument.

Understand the limits

Arbitir analyzes writing, not a student’s cognitive ability. It is not an automatic grading system or proof of AI use. Follow your institution’s rules for handling student work; reports can retain limited quotations.

Arbitir checks a defined set of tactics expressed in text. It cannot guarantee detection of every cognitive bias. Long sources may be shortened to account limits; check the words analyzed.
