TikTok's Smart Split AI makes short, captioned vertical clips from chosen parts
When I first saw TikTok’s newest AI-driven tool, I thought it might finally ease the grind of turning long videos into bite-size clips for the feed. Brands and influencers are clearly racing for more engagement, and the whole process of trimming, captioning and re-formatting has become a real choke point. The feature, now live in the TikTok Studio Web management platform, lets you pick the moments you want to showcase.
From there the AI decides how long each snippet should be, adds subtitles and flips the frame to a vertical layout. It’s rolling out worldwide, which hints that TikTok expects a surge in demand for quick, captioned vertical snippets across its user base.

You select what parts of the video you want turned into shorter clips and Smart Split will handle the rest including choosing the length, generating captions, and even reframing content vertically. It's now available globally through the TikTok Studio Web management platform. AI Outline is a tool designed to be used before anything is even recorded.
As the name implies it uses AI to generate an outline for a video based on a prompt or by selecting a highly searched topic on the platform. The outline includes automatically generated video titles, hashtags, hooks, and script ideas, which creators can edit and refine to match their own style. But unlike Smart Split, AI Outline is getting a more limited release.
It is only available starting today for TikTok creators over 18 in the US, Canada, and "select markets," with a broader rollout happening in the coming weeks. TikTok creators who offer a subscription fee that provides access to perks like exclusive content currently receive 70 percent of TikTok's revenue share after fees. But creators who meet criteria including having at least 10,000 followers, 100,000 views in the last month, and who posted at least three subscription-only videos last month, will be able to unlock extra monthly rewards boosting their revenue share to up to 90 percent.

Will creators jump on the new workflow? TikTok says its Smart Split can shave a few minutes off editing by automatically trimming, adding captions and reformatting long videos for vertical viewing. The tool works on any clip over a minute; creators pick the parts they want to keep while the AI suggests a final length.
It also spits out captions without any typing, which could make videos more accessible. Right now it’s live on the TikTok Studio web platform, bundled with other updates rolled out at the U.S. Creator Summit, a revised revenue-share model for subscription-based creators and an AI Outline planning aid.
Still, it’s unclear how well the AI will spot the most engaging moments or whether the auto-generated captions will pass community standards. Some creators might like the time-saving angle, but the reliance on algorithmic choices could feel like a loss of creative control. As the feature spreads worldwide, TikTok will probably watch adoption numbers and user feedback to tweak the system.
