YouTube adds AI creator tools, from A/B testing to live dubbing

YouTube on Wednesday unveiled a slate of new creator tools, many of which use AI to test different tactics on videos and find what makes them perform best. A new Ask Studio feature lets creators share draft videos with AI to get personalized feedback based on their past content and viewer comments; it proposes alternative titles and thumbnail options, analyzes a channel’s analytics to explain how videos have performed, and offers advice on improving metrics. Ask Studio is expanding to YouTube’s mobile apps as well.

YouTube already lets creators A/B test titles and thumbnails, and starting in 2027, the feature will let creators upload and test three different cuts for Shorts. A new Dynamic Thumbnails feature lets creators upload multiple thumbnails and leaves it to YouTube to determine which one to show each viewer based on what’s most likely to spark their interest. Creators can apply these tools to their existing catalog too — with permission, Ask Studio can autonomously monitor thumbnail performance on older videos and create tests to refine them.

On the shopping side, YouTube will use AI to auto-tag products, which the company says will help creators earn money through affiliate programs; it’s also expanding its Amazon affiliate program beyond the U.S. Some creators remain skeptical of letting AI touch their content, worried that a single AI-generated mistake could damage their credibility — a bar these tools will need to clear to win them over.

YouTube is also expanding how creators go live. Early next year, the platform will pilot auto-dubbing on live videos, translating a creator’s speech into other languages in real time. It’s also launching a “live showdown” feature that lets creators co-host streams together, including pairing with other creators currently streaming through “live creator matchmaking.” “Co-hosts can kick off friendly head-to-head matchups, where viewers send chats, gifts, and Super Chats to push their creator’s score forward on-screen in real time,” YouTube Live product manager Barbara MacDonald wrote in a blog post.

YouTube also shared viewing data alongside the announcements: more people are watching YouTube on household TVs, and more than half of the platform’s top 100 creators now count “living room” as their most-watched interface. Microdramas on YouTube surpassed 6.5 billion views in the first half of 2026, with watch time up 50% year-over-year, while microdrama viewing on TVs specifically rose 90% year-over-year.

Why it matters

YouTube is betting that AI-assisted production tools and a stronger TV push — not just algorithm tweaks — are what keep creators, and their audiences, on the platform rather than rivals.
