Many people use ChatGPT as a secondary search engine, but there are times when you’ll want to go deeper than a quick Q&A prompt. You might be looking to learn a new skill, tackle something for work, help with your child’s homework or simply explore your curiosities.

Now you can do it all on one AI platform, instead of jumping between Google, ChatGPT, YouTube, podcasts, books, journals, encyclopedias and more.
