What's New in Growth Hacking/Growth Marketing?
Strategies
YouTube Expands Voice Replies, Superchat Goals, AI Creation Tools and More
YouTube's year-end feature update introduces new ways to boost engagement: expanded voice replies, auto-dubbing preferences, launch of its Create app for iOS, Superchat goals for vertical livestreams, AI-powered image editing (“Nano Banana”), auto-generated Shorts clips from long-form videos, comment summaries, and testing changes to the Shorts “dislike” button all potentially enhancing growth and creator-audience interaction.
The Future Of Content In An AI World: Provenance & Trust In Information
Discussions with Emily Anne Epstein suggest publishers must compete for trust (not just attention): transparent editorial standards, clear sourcing, and a “blockchain” approach to information provenance will be crucial. Content marketers must provide depth, context, and verifiable value as AI dominates first-layer information delivery. Insightful for digital trust strategies.
Luma releases a new AI model that lets users generate a video from a start and end frame
Luma, the a16z-backed AI video and 3D model company, released a new model called Ray3 Modify that allows users to modify existing footage by providing character reference images that preserve the performance of the original footage. Users can also provide a start and an end frame to guide the model to generate transitional footage.
Google Adds AI Content Detection Tools to Gemini
One of the side effects of the rapid rise of AI-generated content online is that it is also impacting sharing activity, due to questions about the authenticity of the visuals being presented. You don’t want to be that person, sharing clips that everyone else sees as clearly AI, which is making users more skeptical, and more hesitant to forward things that could be fake.
