About Supercut

Supercut is a video editor you talk to. You drop in a clip, type the edit you want, and get the cut back. The part that makes it unusual is what does not happen: your video is never uploaded. Every frame is decoded, edited and exported on the machine you are sitting at, which is why it keeps working with the network unplugged.

Who builds it

Supercut is built and run by an independent developer, operating from Singapore. It is not a ByteDance product, it is not affiliated with CapCut, and there is no venture money behind it. That matters for a practical reason rather than a romantic one: a small paid product has no reason to build the upload pipeline that a large free one needs, and no second business that your footage would be useful to.

Support is answered by the person who wrote the code. Write to support@supercut.cc and that is who replies, usually within one business day. There is more on how to reach us, including press and security, on the contact page.

What we hold to

The footage does not move

Every decode, edit and export runs in your browser through FFmpeg compiled to WebAssembly, or through a native binary in the desktop app. There is no upload step, no render queue and no bucket with your files in it. The one network call an edit makes carries your prompt text and clip metadata, never a frame.

The model plans, it does not watch

When you type "crop this vertical and burn in captions", the model receives that sentence plus the duration, dimensions and filename of your clip. It returns a structured operation. A deterministic mapper turns that operation into FFmpeg arguments. The pixels are never part of the conversation.

Deterministic where it counts

The 43 editing operations are ordinary FFmpeg work, not model output. That is why the same prompt on the same clip gives the same result twice, and why a bug in an edit is a bug we can fix rather than a phrasing to retry.

Paid product, not an ad product

Supercut is funded by people buying it. There is no ad network, no data broker and nothing to sell, which is a large part of why the privacy claim is cheap for us to keep.

Three names, one product

If you have seen this product under another name, you saw the same product. The engine never forked.

  1. 1
    CapCutGPT

    It started as a single question: could you edit a video by describing the edit, without uploading it anywhere? The first version answered that, and capcutgpt.com is still live running the same engine.

  2. 2
    UnoCut

    The name had to change. CapCut is ByteDance’s product and this has never been affiliated with it, so a name that borrowed theirs was misleading whatever the intent. UnoCut was the rebrand, along with a command-first redesign of the editor.

  3. 3
    Supercut

    The current name, and the one the product ships under: a web app at supercut.cc, a Mac App Store release, and notarized desktop builds for macOS and Windows that add a screen recorder and a local MCP server.

What Supercut is not

  • Not a cloud editor. There is no render farm, so there is nothing to queue behind and nothing to leak.
  • Not a collaborative editor. Projects are yours, on your disk, and there are no shared timelines.
  • Not a mobile app. It runs in a desktop browser, or as a desktop app for macOS and Windows.
  • Not a good fit for very large files on a low-memory machine, because a browser tab has a heap and a 4K feature film will exhaust it.

For agents and researchers

Every page of this site is published as plain text so you do not have to parse the markup: llms.txt for the index, llms-full.txt for the whole corpus, the Markdown catalog for one page at a time, and ai.txt for what you may do with it. There is a hosted MCP server at supercut.cc/mcp and a full index of developer resources at supercut.cc/docs.
