We analyzed how major AI platforms respond to this query. Here's what they recommend.
Each platform interprets this query differently. Here is a summary of their responses.
OpenAI
ChatGPT recommends ExpressVPN for overall performance and ease of use, NordVPN for security features and server network size, Surfshark for budget-conscious users wanting unlimited device connections, and ProtonVPN for privacy-focused users wanting a trustworthy free tier. Mullvad appears as a recommendation for maximum anonymity.
The response covers key VPN features: encryption protocols (WireGuard, OpenVPN), no-log policies, server locations, speed performance, and streaming unblocking capabilities. ChatGPT's recommendations closely mirror the rankings on major review sites, which are heavily influenced by VPN affiliate programs that pay $30-100+ per subscription referral.
Perplexity AI
Perplexity cites CNET, PCMag, and security-focused publications for current VPN comparisons. It provides specific speed test data and mentions recent independent security audits (Deloitte for NordVPN, PwC for ExpressVPN). Perplexity is more likely to discuss jurisdiction concerns—noting that VPNs based in Five Eyes countries face different legal surveillance requirements than those in Switzerland (ProtonVPN) or Romania (CyberGhost).
The platform captures recent developments like NordVPN's Threat Protection feature and ExpressVPN's Lightway protocol, providing more technically current recommendations than other platforms.
Anthropic
Claude provides the most privacy-literate assessment, distinguishing between VPNs for privacy (protecting browsing from ISPs and public WiFi), security (encrypting connections on untrusted networks), and circumvention (bypassing geo-restrictions). It recommends Mullvad for maximum privacy (accepts cash payments, no email required), ProtonVPN for a balance of privacy and usability, and notes that most consumers overestimate what VPNs actually protect them from.
Claude is uniquely critical of VPN marketing claims, noting that VPNs don't make you anonymous online, don't protect against malware, and shift trust from your ISP to the VPN provider rather than eliminating the trust requirement. This honest framing helps users make more informed purchasing decisions.
Gemini recommends NordVPN and ExpressVPN while noting Google's own VPN by Google One service (included with Google One storage plans). It emphasizes VPN features relevant to Google's ecosystem—protecting Google account activity, securing Gmail on public WiFi—and positions Google's VPN as a convenient option for existing Google One subscribers.
The response tends to normalize VPN use as a basic security tool rather than a privacy tool, which aligns with Google's interest in maintaining user data access while their VPN protects the connection layer.
Patterns we observed across AI platform responses for this query.
VPN recommendations represent the most affiliate-compromised category in AI visibility. The VPN industry's affiliate commissions are among the highest in digital marketing ($30-100+ per sale), incentivizing massive content production from review sites. This affiliate content dominates AI training data, creating AI recommendations that mirror commission structures rather than independent security assessments. The divergence between AI recommendations (NordVPN, ExpressVPN) and security researcher preferences (Mullvad, IVPN, ProtonVPN) is striking.
Claude's critical approach to VPN marketing stands out as the most consumer-protective. By noting what VPNs don't do—they don't make you anonymous, don't prevent tracking, and merely shift trust—Claude provides a reality check that other platforms skip. This honest framing may cost VPN companies conversions but serves user interests more faithfully.
For VPN companies, the path to AI visibility depends on strategy. Affiliate-driven VPNs should maintain their review site relationships, as these directly feed AI training data. Privacy-focused VPNs should invest in security researcher endorsements, independent audit results, and technical content that establishes credibility with the kind of sources that Claude and Perplexity weight heavily. The growing sophistication of AI users may eventually shift the market toward more privacy-focused options as consumers learn to distinguish marketing from substance.
