Have had a few pet projects in the past around RSS aggregation/news reading, which could fact-check the sources/article while reading, also determining the biases from the grammar and linguistic patterns used by the journalist for the article. Same could be applied to comments.

Wonder if such a feature had value for a reader app for Lemmy? I feel a definitive score is toxic. But, if it were to simply display the variables to look out for it can help make a objective decision yourself?

Another application of this, is also pulling just the objective statements in the articles for faster reading.
