Singtel x Perplexity (CAST) Frequently Asked Questions
What exactly can I get when I redeem this reward?
You’ll get a 12-month subscription of Perplexity Pro (worth ~SGD270) for every mobile line you have under Singtel, for free! Search smarter with an AI-powered tool that gives real-time answers to your questions with information from across the Internet, all in a single response.
Do note that you can only redeem one subscription per email.
What is Perplexity AI?
Perplexity is an 'answer engine,' combining a search engine with an AI chatbot-style interface. When you ask Perplexity a question, its technology searches the web for the most relevant sources of real-time information and then summarises the details into one single, clear answer. There’s no need to go through lines of search results — just ask a question and it does the work for you.
You will receive an email from us if you are eligible.
