AI-Generated Highlights Take Substack Livestreaming to the Next Level
The most exciting part of the latest Substack livestreaming updates is the introduction of AI-generated highlight clips. After a livestream ends, Substack uses artificial intelligence to scan the video and automatically generate short, impactful segments. These clips can then be shared on Substack’s native Notes feature and other platforms like YouTube Shorts, helping creators repurpose content without spending hours editing.
Once creators link their YouTube accounts, the top-performing two clips will be auto-uploaded to their Shorts feed. This seamless cross-platform promotion not only boosts visibility but also saves creators time and effort. For publishers who want to test their clip performance before uploading, Substack provides real-time feedback so they can fine-tune which content is worth sharing. This smart use of AI meets current SEO and engagement trends by focusing on short-form, high-impact content that drives reach and retention.
Substack Livestreaming Updates Include Guest Invites and Promo Tools
Another noteworthy improvement in the Substack livestreaming updates is the addition of flexible guest invitation options. Creators can now invite guests to their livestreams via email or SMS, making it easier to bring collaborators or audience members into the stream—even if they don’t have a Substack account. This is a small but significant change, especially for guest speakers or audience participation segments.
Additionally, Substack now automatically generates promotional assets once a livestream is scheduled. These assets are tailored for platforms like Notes, YouTube, and other major social networks. By eliminating the need for manual content creation, Substack enables publishers to focus on engaging with their audience rather than worrying about logistics. These assets are designed with shareability in mind, boosting discoverability on social channels and aligning with helpful content signals that Google prioritizes in 2025.
A Shift Toward Full-Fledged Video Publishing on Substack
The Substack livestreaming updates are part of a broader shift in the company’s strategy to become a multi-format platform. While originally built for long-form newsletters, Substack has gradually embraced podcasting, video uploads, and now livestreaming with robust feature sets. Earlier this year, Substack introduced a scrollable video feed and live audio options—features that hint at a TikTok-style interface, optimized for content discovery.
With this latest round of updates, Substack is clearly positioning itself as a creator-first platform that values versatility and ease-of-use. The livestreaming tools are now available to all publishers, with the AI highlight feature currently live on iOS and coming soon to Android. As more creators turn to video to engage audiences and build communities, Substack’s commitment to video innovation sets it apart in an increasingly crowded creator economy.
Why Substack Livestreaming Updates Matter for Creators in 2025
In a digital landscape where video content dominates engagement metrics, Substack’s new features couldn’t have arrived at a better time. The AI-driven highlights, integrated YouTube Shorts sharing, flexible guest invites, and automatic promotional tools reflect what today’s content creators need: simplicity, speed, and reach.
For creators focused on growing their audience while maintaining quality and efficiency, these Substack livestreaming updates offer real value. They also align with Google’s E-E-A-T principles—enhancing experience, demonstrating expertise, building authority, and reinforcing trust by streamlining audience interaction and multi-platform content delivery.
As 2025 unfolds, expect more creators to explore Substack’s video potential—not just as a supplement to newsletters, but as a core part of their content strategy.
