Outsourcing due diligence to a tool (or a single unified source) is the problem, not the solution.

For example, having a single central arbiter of source bias is inescapably the most biased thing you could possibly do. Bias has to be defined within an intellectual paradigm. So you'd have to choose a paradigm to use for that bias evaluation, and de facto declare it to be the one true paradigm for this purpose. But intellectual paradigms are inherently subjective, so doing that is pretty much the most intellectually biased thing you can possibly do.
