tbh, this is a tricky one. i haven't seen a single tool that perfectly tracks every citation from perplexity or gemini accurately across the board. they often pull from such a wide range of sources, some paywalled or internal, that it's tough. most people i know just manually check the main links provided if accuracy is really important, or try to reverse-search key phrases if the source isn't clear. wish there was an easier way, tho!
