Substack, initially known for newsletters, is expanding its platform by introducing video creation and editing tools, highlighting the growing importance of video content for online audience engagement. This shift in focus suggests a change in Substack’s business model, potentially pitting it against major video-centric social media platforms such as YouTube, TikTok, and Instagram. This move also positions Substack in direct competition with platforms like Patreon, where users can charge subscriptions for diverse content formats.
