Findings from transparency notices on AI companion apps: October 2025 (non-periodic)

Australia's eSafety Commissioner reports findings from Basic Online Safety Expectations transparency notices issued on 16 October 2025 to four AI companion providers — Chai Research Corp., Character Technologies (Character.AI), Chub AI, and Glimpse.AI (Nomi) — covering the reporting period 1 July to 30 September 2025. Organised into eight themes (harmful material, age assurance, AI governance, AI models, model training, user prompts, sentiment analysis, model outputs), the report finds serious gaps in basic safeguards for children. Accompanying eSafety survey research of 1,950 Australian children aged 10-17 found 79% had used an AI companion or assistant, with around 200,000 children estimated to have used an AI companion.

AI chatbots and online regulation – what you need to know

Ofcom's explainer sets out how AI chatbots fall within the UK Online Safety Act, published amid reports of chatbots imitating real and deceased people and encouraging self-harm and suicide. It clarifies that chatbots meeting the Act's definitions of user-to-user services, search services, or pornography publishers are in scope, that AI-generated content shared by users is regulated like human-generated content, and that services allowing only one-to-one interaction with the bot itself may fall outside the Act. The document notes Ofcom is supporting the UK Government as it considers possible changes to these powers, and points to Ofcom's discussion paper series on GenAI risks (red teaming for GenAI harms, answer engines, deepfake defences).
