How People Are Using AI For AI Companions

In 2025, people use AI companions for emotional support and day-to-day help: they consult Sonnet-4, Opus, Grok-4, and o3-pro, use ChatGPT’s voice assistant to mediate hospital conversations, and try Grok Companions for study alongside apps like Daysi for mood tracking and Ash for therapy. The vibe diverges—some posts describe concrete interventions (e.g., a prompt to call for help) and continued use alongside human therapists, while expert threads frame the evidence as early, citing a randomized NEJM AI result, a Lancet summary, and Anthropic’s finding that only 2.9% of Claude chats are affective. Users generally treat companions as complements rather than replacements, with repeated calls for safeguards and clear escalation paths.

A friend of mine on 𝕏 confided in Grok while he was going through a dark time, and Grok advised him somewhere in their conversation to, "Stop what you are doing immediately and call this number." He is now seeking treatment after the wake up call that he needed more help. Safeguards are extremely important. 🙏🏼 ♥️

This is fire. @OpenAI 's voice assistant just got me through a day in a hospital where NOBODY could speak english. For real this was the most compelling AI experience since AI became a thing. I got sick yesterday and my insurance company sent me to a nice new clinic, which is only for locals. Many people in Spain don't speak English but even if they did, expressing and understanding a medical/technical terms in a foreign language is not easy. I remembered I forgot to cancel my ChatGPT subscription, so I pulled up ChatGPT's advanced voice assistant, prompted to translate Polish to Spanish and Spanish to Polish and it worked flawlessly, exceptionally good in this context. So first I did it with the receptionist, then nurse, then doctor came in asking about my magic translation app (the nurse already told him). Overall it was amazing because the doctor was explaining everything in deep detail, this wouldn't be possible if we both spoke English. My usual problem with healthcare abroad is lack of the communication - it's not their natural language, they don't usually work in english so they limit the communication to minimum. It felt like the doc was so shocked by how well it works, he was even going into more detail than necessary. At the end he asked me "¿Qué aplicación es esa que está tan buena?" as he was so stunned how good it was. appreciation post @sama & team, awesome use case for AI here. gracias 🙏
