What the research found
Reviewing the evidence on how general-purpose chatbots and AI companions handle suicide risk disclosures, researchers at Crisis Text Line found that nearly all existing safety tests rely on single-turn, researcher-scripted prompts rather than the indirect, gradually-disclosed way teens actually talk, and that chatbot performance degrades sharply on exactly those realistic patterns. No study has yet measured what happens to real teens' suicide risk after they talk to a chatbot. The authors lay out a research agenda to close that gap.
The riskiest population is using the least-tested product feature, and providers still have no real-world evidence of harm or benefit to act on, only lab-style tests that don't resemble how a struggling teen actually opens up.
