I’m researching how a few companies have changed their subscription prices over the last several years. Current pricing pages are easy to find, but older prices tend to live in dated announcements, archived pages, or third-party coverage.

Has Perplexity been useful for this kind of historical price research? I’m curious whether it can surface sources from different years and make it clear which price applied when, rather than blending old and current information together. If you’ve tried this, what source types did you find most dependable?
