Google, Wolfram Alpha, and ChatGPT all interact with users via a single-line text entry field and provide text results. Google returns search results, a list of web pages and articles that will (hopefully) provide information related to the search queries. Wolfram Alpha generally provides answers that are mathematical and data analysis-related.
ChatGPT users should be wary that their personal data might've been leaked online, following the dump of more than 100,000 ChatGPT account credentials on the dark web. As reported by The Hacker News and according to Singapore-based cybersecurity company Group-IB, the credentials for users that logged into ChatGPT ranges from its launch (in June 2022) through May 2023, meaning that it's still an ongoing event. The U.S., France, Morocco, Indonesia, Pakistan, and Brazil seem to have contributed the most users towards the stolen credentials.
