OpusCut

What OpusCut is

OpusCut is a browser-based AI video toolkit for turning long videos into short clips, subtitles, and voiceovers. Users can provide YouTube or Google Drive links, or upload common video formats up to 10 GB. Its highlight tool analyzes speech, emotion, and narrative completeness to find standalone moments, reframe them vertically, and add captions. Caption styles include KTV, Opus Pop, and static options, with customizable brand colors and font uploads. The subtitle tool transcribes speech, aligns captions to individual words, burns them into video, and offers SRT export on paid plans. Text-to-voice includes Chinese, English, and Japanese voices from the ElevenLabs library. Other listed AI editing actions include titles and emojis, two-speaker splitting, and automatic audio synchronization. OpusCut also provides an MCP server to connect tools such as Claude, Cursor, and ChatGPT to OpusCut tasks. New accounts receive 50 free credits, and the service says no credit card is required to try it. The Free plan includes three downloads per month; paid plans add monthly credits and features such as unlimited downloads, no watermark, 4K downloads, and SRT downloads. Generated clips and caption files are kept for seven days by default, while original submitted videos are not permanently stored.

Who it suits

OpusCut suits creators who want to turn longer footage into vertical clips with captions, subtitles, or voiceovers in a browser. It can also fit teams that want custom caption styling or to connect AI tools to OpusCut tasks.

Limits

The Free plan provides 50 one-time credits and three downloads per month. Generated clips and caption files are stored for seven days by default, then automatically deleted.

Getting started

1. Visit opuscut.app in a web browser.
2. Create an account to receive 50 free credits; no credit card is required to try it.
3. Provide a YouTube or Google Drive link, or upload a common video format up to 10 GB.
4. Choose a free or paid plan based on the credit and download limits you need.
5. Use the editor to create clips, captions, subtitles, or voiceovers.

Verdict

OpusCut is a fit for browser-based short-form editing with highlight detection, reframing, captions, and voiceover tools. Look elsewhere if you need TikTok or Instagram links as supported input sources, or need SRT export without a paid plan.
