Originally unveiled by Google Labs in December, Jules is positioned as a reliable, automated coding assistant that can manage a broad suite of time-consuming tasks on behalf of human users.

Explore historical events through multiple lenses – political, economic, social, and cultural. Direct your AI research assistant to focus on specific date ranges, if relevant. Ask it draw from diverse sources across countries and perspectives. Ask for comparisons across countries, regions or time periods

Google launches AI Mode in Search for US users, allowing people to chat with AI directly and ask complex questions.

Announcing a partnership with PayPal, Perplexity will now let users in the U.S. make purchases directly in the chatbot. This will include booking flights, buying products, and getting your hands on concert tickets without having to leave the Perplexity platform.
