Perplexity embarked on a significant growth initiative over the past year, offering its premium AI service, Perplexity Pro, free of charge to customers of Indian telecom giant Airtel. This extensive experiment, which saw the earliest free subscriptions begin to expire recently, serves as a crucial test case for whether bundling paid AI services can cultivate a loyal user base and generate sustainable revenue after a promotional period concludes.

The partnership, initiated in July 2025, provided Airtel’s 360 million subscribers with a complimentary 12-month Perplexity Pro subscription, typically valued at approximately $200. While new redemptions ceased on January 16, the year-long access meant that the initial wave of users reached the end of their free period last month, necessitating an opt-out from auto-renewal to avoid charges. The impact was immediate and substantial: Perplexity recorded 5.9 million app downloads in India in July 2025, a staggering 625% increase from the previous month and surpassing the total downloads accumulated in the entire first half of that year. This momentum continued, with 56 million downloads during the seven months the offer was active, a more than nine-fold increase over the preceding period. Monthly active users more than doubled to 8.9 million in July, peaking at 22 million in October.

India, with its vast population, over a billion internet subscribers, and affordable mobile data, has long been a critical market for global technology companies and is now a major source of users for generative AI services. However, translating this immense scale into revenue has proven challenging. Following the closure of the free Airtel subscription window in January, Perplexity’s downloads sharply declined, falling over 90% between February and July compared to the preceding six months. Despite this, the retention of active users has been notably resilient; monthly active users stood at nearly 14 million in July, a 37% drop from the October peak but still more than five times the average from the first half of 2025.

More strikingly, the decline in downloads has not been mirrored by a drop in spending. Perplexity’s in-app purchase and subscription revenue in India between February and mid-August rose approximately 60% from the period when the Airtel offer was available. This trend persisted even as the earliest Airtel subscribers began losing their free access, with average daily revenue showing further increases. While this suggests some users may be willing to pay after experiencing the premium service, it’s also possible that a portion of this revenue increase stems from users who did not cancel their auto-renewing subscriptions in time. This experiment by Perplexity precedes similar moves by other AI giants, with OpenAI offering a free ChatGPT Go plan and Google partnering with Reliance Jio for its AI Pro subscription, positioning Perplexity as an early indicator of the viability of this monetization strategy in India’s price-sensitive market.

Key Takeaways

• Perplexity's year-long free premium AI offer with Airtel in India led to a massive surge in app downloads and active users, peaking at 22 million monthly active users.
• Post-offer, downloads sharply declined, but active user retention remained strong, and surprisingly, in-app purchase revenue significantly increased.
• The experiment provides early insights into the challenges and potential of converting free users into paying subscribers in a price-sensitive market, setting a precedent for similar initiatives by OpenAI and Google in India.

Editor’s Analysis & Impact

Perplexity’s extensive free AI subscription experiment in India offers critical insights into the monetization strategies for generative AI in emerging markets. The initial surge in users underscores India’s immense potential as a growth engine for AI adoption. However, the subsequent sharp drop in downloads highlights the challenge of sustaining organic growth once promotional incentives cease. The unexpected increase in revenue, despite declining downloads, suggests a complex interplay of successful conversions and potential auto-renewal defaults. This case study will be closely watched by competitors like Google and OpenAI, who have launched similar initiatives. The long-term success hinges on whether users genuinely perceive enough value to pay, rather than simply failing to cancel. This experiment will shape future business models for AI companies targeting large, price-sensitive consumer bases globally.

Frequently Asked Questions

Q: What was Perplexity's AI experiment in India?
A: Perplexity partnered with Indian telecom giant Airtel to offer a free 12-month subscription to its premium AI service, Perplexity Pro, to Airtel's 360 million customers. This aimed to rapidly expand its user base and test the viability of converting free users into paying subscribers.

Q: Did the free offer successfully convert users into paying customers?
A: While downloads significantly decreased after the free offer ended, Perplexity's in-app purchase and subscription revenue in India actually increased. This suggests some users are converting, or at least not canceling their auto-renewing subscriptions, indicating a potential for monetization, though the exact conversion rate of former free users is not definitively known.

Q: What are the broader implications of this experiment for other AI companies?
A: Perplexity's experience serves as an early test case for the 'freemium' model in large, price-sensitive markets like India. Its results will inform strategies for other major AI players like OpenAI and Google, who have launched similar free subscription offers, on how to effectively acquire users and eventually monetize them in these crucial growth regions.
