Unless otherwise stated in a separate written agreement or speaker release, Underline does not claim ownership of speaker presentations, slides, posters, abstracts, papers, or research materials.

Event organizers, venues, speakers, sponsors, societies, publishers, institutions, or other third parties may change, postpone, cancel, modify, or restrict events, sessions, speakers, formats, livestreams, recordings, access windows, or related services.

Underline is not responsible for event changes, cancellations, postponements, travel costs, hotel costs, lost opportunities, or other losses caused by third-party event decisions, force majeure events, technical disruptions outside Underline's reasonable control, venue issues, speaker non-attendance, organizer decisions, or other circumstances beyond Underline's control.

Refunds for event registration or Customer event services are governed by the applicable event registration terms, Customer agreement, invoice, or written event policy.

16. AI-Powered Search, Recommendations, Summaries, and Transcripts

The Services may include AI-powered search, recommendation, transcript, translation, summarization, question-answering, citation, metadata, or discovery features.

AI-generated or machine-generated outputs may be incomplete, inaccurate, outdated, or not reflect the full context of the underlying Content. You should verify important information against the original source Content and other authoritative sources.

AI-generated outputs, search results, recommendations, transcripts, translations, and summaries are provided for research, discovery, accessibility, and convenience. They are not professional advice, medical advice, legal advice, clinical guidance, engineering advice, financial advice, or a substitute for independent expert judgment.

You may not use AI features or outputs to bypass access restrictions, reconstruct restricted Content, create unauthorized derivative works, systematically extract Content, or build competing products.

Content available through the Services may discuss scientific, medical, clinical, technical, legal, financial, policy, or professional topics. Such Content is provided for educational, scholarly, research, informational, or conference-related purposes only.
