Source Evaluator

Evaluate argumentation quality — not factual accuracy.

⚠️ 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

This is not a fact-checker

TellDear evaluates how a text argues, not whether its claims are true. A high-quality score means the argumentation is transparent and logical — the claims may still be wrong. A low score means the text uses problematic reasoning patterns — the claims may still be true.

Longer texts (500+ characters) yield better results. 0 / 5000
