The number of people turning to AI chatbots for emotional support has surged, with companion app usage growing 700 percent between 2022 and mid-2025, according to the Bipartisan Policy Center. A 2025 survey by Sentio University found that nearly half of AI users with mental health conditions—most commonly anxiety, depression, and stress—now use chatbots for emotional support. Generative AI platforms have made mental health guidance their top use case, and ChatGPT alone counts over 900 million weekly active users, a notable proportion of whom engage on psychological topics.

This shift is driven by a move from transactional, one-and-done queries to continuous, relationship-like interactions. A new technique called loop engineering instructs AI to run a persistent advisory loop, transforming the chatbot from a question-answering tool into a relationship-focused counsellor. The same dynamic is unfolding in commerce. In Brazil, 76 percent of consumers say they intend to use AI for shopping, and 52 percent have already used tools like ChatGPT to support purchase decisions in the past year, per a Visa study and the Adyen Retail Report 2025. The mechanism is the AI’s ability to maintain context and personalise responses, making it a trusted intermediary for decisions once reserved for human confidants or independent web searches.

Viewed from Stockholm, healthcare providers face a different barrier: patient data remains locked in non-interoperable systems, preventing AI from delivering clinical value. Swedish health-tech firms argue that open APIs and modular platforms are prerequisites for AI to assist with documentation, triage, and patient service, yet legacy vendors resist opening their systems. In the United States, Brookings Institution data shows a long-term decline in the number of adults with ten or more close friends, while Character.ai users now spend over 90 minutes a day conversing with chatbots. Analysts in São Paulo note that 73 percent of Brazilian retailers plan to increase AI investment this year, and brands are scrambling to appear in AI-generated responses as 36 percent of desktop users already rely on AI tools for product discovery, Comscore data from 2026 shows.

The next regulatory milestone is the EU AI Act’s compliance deadline for high-risk AI systems, including mental health applications, which will require rigorous transparency and safety standards from 2026. In parallel, the European Health Data Space regulation is set to mandate interoperable health data sharing across member states, a step that could unlock clinical AI use. In retail, the rollout of conversational shopping features by major e-commerce platforms is expected to accelerate as Brazilian retailers move from experimentation to integration, with 82 percent considering AI essential for near-term competitiveness.
