I asked versions of this question to a few different models but I never found an accurate answer.

I would like to compare the various free and paid AI subscription plans, primarily from the most popular vendors like ChatGPT, Claude, Google, etc.

I can find countless static webpages, YouTube videos, etc. that compare subscriptions, but their information quickly becomes out-of-date, or isn't detailed enough.

I'm looking for a tool that grabs the latest information on what each plan provides (features, models, context windows, etc.), and compares them across different subscriptions. I imagine this information would be obtained from API calls or scraping. The comparison tool should not rely on AI to get its information.. I want the latest facts (ideally checked at least once a day).
