TikTok announces two new AI tools for creators: Smart Split and AI Outline
TikTok just dropped a whole host of new tools and features — including new monthly rewards and so, so much AI.
Long videos are great for YouTube, but they might not be ideal for short-form video. Enter: Smart Split, an AI-powered editing tool that takes your longer videos — think podcast videos and hour-long video essays — and clips them into shorter videos.
"If you've ever spent hours trimming down podcasts into clips… this one is for you," Kim Farrell, the global head of creators at TikTok, said at TikTok's 2025 U.S. Creator Summit.

The tool, which is available globally on TikTok Studio Web, automatically clips, reframes, captions, and transcribes users' longer videos into multiple short videos. To use the tool, creators still need to do a bit of work. You'll have to upload videos that are longer than one minute and select which parts you want clipped. Then, either decide how long you want the videos to be or let Smart Split automatically choose the length. You can also choose the caption formatting and reframe the content if necessary.
The platform also launched AI Outline, an AI-powered tool that gives creators video titles, hashtags, hooks, and outlines. Simply enter a prompt or select a topic on Creator Search Insights to get an outline that breaks a video down into six parts. After you get the AI response, you can ask it to edit the response — i.e., ask for it to give you another hook option or make the script better fit your audience. AI Outline is available for creators 18 years or older in the U.S., Canada, and select markets.
It's not surprising that TikTok would continue to lean into AI — it seems every social media platform is. Earlier this month, Twitch announced a new AI-powered tool that automatically creates clips from livestreams, kind of like the Twitch version of Smart Split. Meta has its own array of AI-powered tools for creators, like AI tools on Edit, AI Studio, and the "infinite slop machine" that is Meta AI's Vibes.
