Overview

• Google says the features are available starting today and will reach all users over the coming week.
• Video Overviews now generate narrated slide summaries in 80 languages based on a user's notebook content.
• Non-English Audio Overviews move from brief highlights to full-length discussions matching the English experience, with a shorter option still available.
• Overviews are grounded in uploaded sources, pulling visuals and synthesized summaries directly from users’ documents rather than the open web.
• The mobile app adds in‑app output language selection, response‑length controls and guiding prompts, with Google reporting a 95% reduction in buffering.
