Description
Koustuv Saha and co-authors compare AI answers with human answers to mental health posts in 2026 work. Online communities give peer support around the clock, and chatbots now promise the same at larger scale. Whether machine words match the feel of peer support was untested.
The team drew on more than 24,000 posts and about 139,000 human replies from 55 Reddit communities. Three leading chatbots answered the same posts for comparison. Machine replies ran longer, read more smoothly, and sounded more orderly. Human replies carried more varied words and personal stories. The authors favor blends that keep human warmth while using machine speed.
