Airtel's free Perplexity Pro AI offer is ending, and users are being notified about renewal. The offer was a special 1-year subscription worth up to Rs 17,000 bundled with Airtel postpaid, prepaid, and Wi-Fi plans last year. Users who signed up are receiving a message stating: “Your annual Perplexity subscription is due for renewal. If you do not wish to continue, please cancel your auto-renewal mandate before the renewal date to avoid any additional charges. To unsubscribe, open the Perplexity app, Visit Profile Section and Click View Details to Unsubscribe." The offer required users to add a valid payment method to continue the trial, with the company stating, “Your card will only be charged after your trial offer ends, and your subscription will renew automatically unless cancelled beforehand." Users who never added payment details can ignore the message, while those who did should cancel the subscription before being billed.
