What the evaluation found
Pangram
Strongest category: Impact, Ethics, And Safety
Pangram projects an image of transparency and responsibility, publishing extensive documentation on its internal governance, fairness testing, and product limitations. However, the evidence supporting its key claims of accuracy and fairness comes almost entirely from the company itself, without formal, independent audits to verify them. This lack of external validation is significant, as independent users report frequent false positives and unreliable results that contradict the company's marketing.

Strongest category: Quality
Undetectable.ai demonstrates highly inconsistent performance, excelling at identifying simple, unedited AI or human writing but struggling significantly with more complex material. In controlled huby testing, the tool correctly identified all purely human-written documents but failed to flag two-thirds of AI-generated text that was edited or designed to be evasive. This performance gap extends to its rewriting feature, where the paid version can bypass some detectors while the free version is completely ineffective.
