We search the internet for sources and explicitly prioritize websites that have been identified by educators that are trustworthy and we exclude sources from websites that are known to include bias (e.g. Reddit), however, different teachers might have different opinions on what is credible (e.g Wikipedia). To view and edit sources, add "with cited sources" to the end of your prompt, Diffit should provide the sources it's using. You can also always ask Diffit Chat to update the readings to include sources.
