Turn long videos into TikTok-ready clips with AI
FastClip scans your YouTube video, finds the moments that stop the scroll, and delivers up to 10 vertical 9:16 clips with animated karaoke captions — all in under a minute. Paste your link and get clips ready to post on TikTok. No editing experience needed.
Built for creators who think TikTok first
Every clip is optimized for the way TikTok actually works — strong hooks, animated captions, full-screen vertical format.
The hook is always at the start
TikTok viewers decide in the first two seconds. FastClip's AI reads the transcript of your full video and picks the moments with the strongest opening line — a bold statement, a question, a punchline — and starts each clip right there. No more burying the best part three seconds in. The clip earns the watch from frame one.
Animated captions that hold muted viewers
Most TikTok views happen with the sound off. FastClip burns in karaoke-style captions that highlight each word as it's spoken, keeping muted viewers in for the whole clip. You pick the caption style — bold pop, clean CapCut look, punchy Hormozi — and tweak the text in the browser editor before you download. The captions come with every clip automatically, no extra step.
9:16 vertical and ready to upload
Every clip comes out at 1080×1920, cropped to fill the phone screen with no black bars. What you download goes directly onto TikTok — no re-cropping, no format converting, no extra app. The browser editor lets you trim the start and end, adjust the caption style, and fine-tune the look before you export, all without leaving the tab.
YouTube to TikTok in three steps
Paste a link and your TikTok clips are ready in about a minute.
Paste your YouTube video link
Drop any YouTube URL into FastClip — podcast, interview, vlog, tutorial, stream highlight. The AI downloads the audio, transcribes every word, and identifies the moments most likely to perform well on TikTok based on what's actually being said.
AI cuts up to 10 clips with captions
FastClip trims each moment into its own 9:16 vertical clip and adds animated karaoke captions synced word-by-word to the speaker. You get a batch of ready clips in about a minute — not one clip at a time. Each clip starts on a strong line and ends before the energy drops.
Edit in the browser and download 1080p
Open any clip in the built-in editor to change the caption style, fix a word, trim the edges, or reframe the video. When it looks right, export 1080p and it's ready to drop on TikTok, Reels, or YouTube Shorts. No installs, no rendering wait — everything runs in the browser.
Why FastClip for YouTube to TikTok
Other AI clipping tools clip a video. FastClip delivers TikTok-ready content.
One video, up to 10 TikTok clips
FastClip doesn't stop at one clip. It scans the whole video, finds every strong moment, and delivers a full batch in a single run. A one-hour interview can become ten clips in the time it used to take to find and cut one. You can post daily from a single piece of long-form content without recording anything new.
Works on any kind of YouTube content
Podcasts, vlogs, interviews, gaming streams, educational videos, cooking shows — FastClip finds the clippable moments regardless of the topic. The AI reads the words, not just the waveform. If someone says something interesting, the AI flags it. Paste the link and find out which moments are worth clipping before you spend time editing manually.
Browser editor — no app to install
Every clip opens in a full browser editor: trim the start and end, switch caption style, reposition the text, adjust the volume. Changes are instant. When you're happy, download the 1080p file. No Premiere, no CapCut download, no After Effects. The whole flow — from YouTube link to polished TikTok clip — happens in a single browser tab.
Frequently asked questions
Can I turn any YouTube video into TikTok clips with FastClip?
Yes. Paste the YouTube URL into FastClip and the AI finds the most engaging moments in the video — hooks, punchlines, stories — and cuts each one into a vertical 9:16 clip ready for TikTok. It works on any public YouTube video: podcasts, vlogs, interviews, tutorials, gaming streams. The AI reads the full transcript and picks the parts most likely to stop the scroll.
What makes a TikTok clip different from a regular short-form video?
TikTok rewards clips that hook the viewer in the first two seconds and keep them watching to the end. FastClip starts every clip at the moment with the strongest opening line, adds karaoke-style animated captions so muted viewers stay engaged, and frames the video in a tight 9:16 crop that fills the phone screen. That combination — strong hook, animated text, full-screen format — is the standard for TikTok-ready content.
Do the clips have subtitles ready for TikTok?
Yes. Every clip comes with animated karaoke captions generated directly from the audio using AI transcription. The captions highlight each word as the speaker says it, in the same style top TikTok creators use. You can change the look (bold pop, clean CapCut style, punchy Hormozi) and fix any word in the browser editor before you download.
How is FastClip different from doing it manually in TikTok's editor?
TikTok's built-in editor cuts one clip at a time and has limited subtitle options. FastClip processes the entire long video at once, finds up to 10 of the strongest moments automatically, and delivers them all pre-captioned in one run. What takes an hour of manual trimming and caption-syncing in TikTok's editor takes under a minute in FastClip. You still get a browser editor to tweak each clip before downloading, so you keep full control.
