AI Personalisation Powers Southeast Asia's Shopping Boom
Sea Group's Shopee is driving a 10% year-on-year lift in advertising conversion rates across Indonesia, Malaysia, and Thailand, leveraging Sailor2, a large language model trained on 400 billion tokens of Southeast Asian transaction data. The model powers real-time product recommendations across shopping feeds, video discovery, and seller matchmaking, embedding cultural nuance and local purchasing intent into every algorithm.
Indonesia's e-commerce market, valued at USD 71 billion in 2025, is the heartland of this AI-driven transformation. Seventy-nine per cent of Shopee users routinely engage with AI-powered features—from visual search to dynamic pricing suggestions—creating a virtuous cycle where algorithmic recommendations fuel transaction volume and, in turn, provide richer training data for Sailor2's next iteration.
The most compelling sign of AI's influence: video commerce adoption. Sellers using short-form video content on Shopee rose 75% year-on-year to 800,000 active storefronts. Video-powered transactions jumped 90% in the same period, accounting for 2.6 billion transactions across ASEAN. This shift reflects AI's ability to surface video content precisely when shoppers are most receptive—often in idle moments when they browse on mobile, precisely matching intent signals that traditional category browse patterns miss.
Malaysian Payment Gateways Embrace Alternative Fintech
Malaysia is witnessing a parallel AI wave in digital payments. Ant International partnered with Adobe in March to launch seven alternative payment methods for global merchants selling to Malaysian consumers, integrating wallets, instalments, and bank transfers into a unified checkout experience powered by machine-learning fraud detection and conversion optimisation.
For Malaysian consumers, the benefit is frictionless checkout: no more card-entry forms, no KYC delays. For merchants—especially small sellers from Thailand, the Philippines, and Vietnam exporting to Malaysia—it cuts payment failure rates by an estimated 15% according to Ant's internal benchmarks, unlocking an estimated USD 2.4 billion in transaction volume that would otherwise abandon cart.
Payment AI also reduces chargeback and fraud loss, a chronic pain point for ASEAN cross-border trade. Ant's models, trained on 8 billion transactions across Asia-Pacific, detect anomalies in real-time, flagging high-risk orders for verification without blocking legitimate transactions.
Thailand's Lifestyle App AI Makes Retail Discovery Personal
Thailand's e-commerce market is smaller than Indonesia's but growing faster. Rising from USD 12 billion in 2024 to USD 18 billion forecast for 2026, growth is driven largely by lifestyle and fashion retail moving onto mobile super-apps. Lazada and TikTok Shop have both deployed generative AI product description tools, dynamically crafting seller listings in Thai language with SEO optimisation, appeal narratives, and even style matching to user browsing history.
TikTok Shop's AI Agent, launched in Bangkok in February, automates the seller onboarding process: sellers upload product images, the AI writes descriptions, assigns categories, and sets recommended price ranges in minutes rather than the manual day-long process. By March 2026, TikTok Shop reported 23,000 active sellers on the platform—a 180% increase year-on-year—with AI-authored product listings converting at 1.8x the rate of manual ones.
For Thai consumers, TikTok Shop's recommendation engine now uses Gemini 1.5 Flash to read seller reviews and social comments in real-time, surfacing products based on contextual sentiment rather than transaction volume alone. This shifts purchasing power towards smaller, independent Thai sellers, undermining the traditional category-and-bestseller retail hierarchy that has favoured large brands.
The AI In Asia View
Sailor2, Ant's fraud models, and TikTok's agent tools are not simply automating rote tasks; they are remaking the topology of ASEAN retail. Smaller merchants—the 800,000 video sellers on Shopee, the 23,000 fresh merchants on TikTok Shop, the cross-border traders on Lazada—are gaining algorithmic parity with incumbent brands. This is democratisation by algorithm, and it is rewiring billions of dollars of consumer purchasing power.
The key metric to watch: seller profitability. When AI improves listing quality and payment success, smaller merchants earn higher margins, which incentivises new seller entry, which enriches training data, which improves recommendations. This virtuous cycle is already visible in Shopee's video metrics and TikTok Shop's seller growth.
