Frequently Asked Questions
What is CapCut?
CapCut is a free video editing app from ByteDance — the company behind TikTok — available on web, desktop, and mobile. It combines a beginner-friendly interface with pro-level tools and an AI suite, and is widely used for producing short-form vertical video for TikTok, Instagram Reels, and YouTube Shorts.
How does the Soku AI integration work?
The integration is workflow-based rather than a live API sync. Soku AI generates the creative concept, hook, and script; you produce the finished edit in CapCut with auto captions, text-to-speech, and templates; then Soku deploys the creatives across Meta, Google, and TikTok and measures which ones perform — feeding that insight back into your next round of edits.
Does CapCut have a public API?
CapCut does not expose a broad public video-editing API for developers. Integration into an ad workflow is handled through exports (platform-ready MP4s), shared templates, and the CapCut for Business ad tools rather than a live data connection.
How much does CapCut cost?
CapCut has a capable free tier. Paid plans (2026 web-app pricing) are Standard at $9.99/month and Pro at $19.99/month, or $179.99/year for Pro (about $15/month). App-store subscriptions run slightly higher due to platform fees.
Can I use CapCut for commercial ads?
Yes, but commercial use — including paid promotions, brand content, and ads — generally requires a Pro or commercial license. CapCut's free built-in music library is not cleared for commercial projects, so use Pro or CapCut for Business assets, which include commercial-use rights, when running paid campaigns.
What is CapCut for Business?
CapCut for Business is a marketer-focused extension of the platform. It adds AI ad-script generation, thousands of commercially licensed business templates, URL-to-video conversion, and AI-generated presenters — all aimed at producing ad and branded content at scale.
How is CapCut different from Canva or Descript?
CapCut is purpose-built for fast, trend-driven short-form video with native TikTok DNA, thousands of video templates, and AI avatars. Canva is a broader design platform with lighter video tools, and Descript specializes in transcript-based editing of video and podcasts. CapCut's free tier and short-form focus make it the go-to for high-volume social ad production.
What AI features does CapCut offer?
CapCut's AI suite includes Auto-Edit (automatic assembly of raw footage), auto captions in 130+ languages, text-to-speech with 269 voices, AI avatars, script-to-video, one-click background removal, retouch, and smart auto reframe across aspect ratios.
Can CapCut help me test more ad creative?
Absolutely. CapCut makes it cheap and fast to produce many caption, hook, and length variants of a video. Paired with Soku AI, you can run those variants as a structured test, identify the top performers, and scale the winners across every channel.
