YouTube is quietly rolling out a new “Collabs” feature that looks and feels a lot like Instagram’s and TikTok’s co-author tools. In the latest test, a select group of creators can tag fellow contributors on a video, so that it shows up not only on the uploader’s channel but also surfaces in collaborators’ recommendations—exposing each participant to new audiences. The feature was first noted by a Google employee in the YouTube Help Community and later illustrated with a screenshot shared by influencer-marketing consultant Lindsey Gamble on Threads.

As seen in Gamble’s screenshot, when a creator adds collaborators, their names appear alongside the uploader’s on the video page. On mobile, if there are more than two or three contributors, YouTube truncates the list to “…and more,” which users can tap to reveal the full roster—with convenient Subscribe buttons next to each name. This mirrors Instagram’s Collabs tool, introduced in July 2022 to let up to two accounts co-author feed posts and Reels, and TikTok’s similar experiment spotted in mid-2024.

Early reports suggest the flow will follow Instagram’s and TikTok’s playbook: the uploading creator invites collaborators, who must accept before their handles are attached. That ensures no one can be tagged without consent—a key safeguard against spam or unwanted associations. What remains unclear is whether collaborators gain any back-end access (for instance, viewing analytics or editing captions), or if the feature is purely for front-end discovery. Given Google’s tendency to lock down who sees creator metrics, it’s likely this remains a one-way street—collaborators get credit and exposure, but nothing more.

Collaboration features have reshaped social-video dynamics. On Instagram, brands and creators have leveraged Collabs to co-launch product teasers or influencer campaigns, instantly pooling their follower bases into one post. TikTok, though quieter about its test, has shown glimpses of brand-to-brand co-posts that can double down on shared audiences. Now, with over 2 billion logged-in monthly users, YouTube stands to supercharge this model on a platform built for longer-form storytelling—potentially unlocking new co-marketing and co-creative possibilities for everything from music videos to how-to tutorials.

Despite the promise, there are question marks. How will YouTube handle revenue splits? If a collab video is monetized, does each collaborator get a share? On Instagram, sponsorship deals typically fall on the uploader, while TikTok’s policy remains murky. YouTube’s longstanding partnership program and AdSense ecosystem might require a more elaborate revamp to support multi-account payouts. And then there’s discoverability: will collab videos be equally prioritized in recommendations for each collaborator, or will the uploader—by default—get the algorithmic boost?

For now, only a small test pool has access. YouTube plans to gather tester feedback—on UX flow, moderation, and any glitches—before deciding on a wider rollout. If all goes well, expect an official announcement in the coming months, perhaps alongside other creator-focused tools in YouTube’s annual VidCon showcase.

As YouTube continues to zero in on creator retention and revenue diversification, adding collaboration features is a strategic move to keep top talent engaged and cross-pollinate audiences across its vast ecosystem.
